12" touch screen lcd for $150 (modified 0 times) piperpacer Profile Found this 12" touch screen lcd for $150 at software and stuff. Might be good for a HTPC project. Its a refurb Planar so it should be decent. http://www.softwareandstuff.com/MON10121.html 07-02-2004 11:54:51

RE:12 (modified 0 times) Musicman50 Profile Yep I just found that earlier today and ordered one myself. These retail all over the internet for $400-$600, so it's a steal.. Better get one quick, they may only have a few, and they will go fast at that price. It has a serial interface to support the touch screen, and the drivers are on their website. Plano only shows one model at 12.1 inch, but it has controls on the front, and the one photo at softwareandstuff.com looks different. Assumming it comes with the drivers for win 95/98, if not I'm sure they could be had at the plano website. ~phil 07-03-2004 14:41:07

RE:12 (modified 0 times) zmoz Profile Interesting, appears to be the same LCD as the computer terminals talked about in this thread: http://www.linux-hacker.net/cgi-bin/UltraBoard/UltraBoard.pl?Action=ShowPost&Board=bnews&Post=701&Idle=0&Sort=0&Order=Descend&Page=0&Session=zmoz.108890486934940 As much as I've searched, there is very little info about this LCD available. It appears to have only been used in various industrial/kiosk applications. All my monitors say "Made by CTX" on the back, but I've seen the exact same monitor with Planar's name on it. If these are indeed the same monitors, don't expect too much picture quality. It is a deal though, hell, I sold about 20 of those monitors without the touchscreen for $150. 07-03-2004 18:38:32

RE:12 (modified 0 times) BigDog Profile | Email Anyone order any of these yet and get them? I ordered a couple and was out looking for drivers for the touchscreen, any links to were to download them? 07-07-2004 06:58:38

RE:12 (modified 1 times) BigDog Profile | Email Just got the two I ordered, one worked one didn't :( So I will see how good the 90 day warrenty is.... These monitors are "used", I'm not sure were the "Refurbished" condition could be applied but they were not packed in orginal packing or checked out that well. No vga cables came with it and it required a VGA cable with male ends on each end. The display is a CTX PV600, the touchscreen controller is what appears to be a standard ELO MicroTouch controller so drivers shouldn't be an issue (it has a RG45 jack on the back which is labeled "Touch Pen", I hope regular finger/stylis functionality works). The max display mode appears to be 640/480 which should work well for HTPC as prev. mentioned, the appearance seems good, the display quality is good at 90 degrees but it really declines at just a few degrees off that. This might be a decent display if you are making a mobile PC for your car if it's a a swivil pivot that you can align correctly to view it. Stay tuned for further details as such as how good the seller's warrenty service is... :) Also meant to add that this is small monitor! perfect if you are looking for something for your work bench in which you don't want to lose a lot of space. 07-12-2004 18:52:50

RE:12 (modified 0 times) Rockhammer Profile | Email max resolution is 640x480...ugh. What kind of shape is the screen surface in? A lot of used touch screens are pretty scratched up. Please keep us posted on your progress. 07-14-2004 06:31:30

RE:12 (modified 0 times) BigDog Profile | Email Arg.. I meant 800x600 on the resolution, sorry about that; the defective monitor I have to send back has something wrong with it and it ONLY works in 800x600, when it is connected to a PC, the screen is all garbled until the higher res mode kicks in. The touch screen works good with the latest 3M Microtouch driver set, I was worried at first if touchscreen required the pen to use the screen but during the driver setup there is an option to select finger, pen or both; I selected finger only and had no issue. The screen is in great shape, one of the screens had some sort of what appear slight scratch in the center area but I believe it's just dust inbetween the LCD and touch screen. SoftwareAndStuff emailed back a reply concerning returning the bad one and indicated after I faxed in a RMA form and received a RMA number, that I could ship the bad one back and they would sned me another; if I want to just return the defective unit and not get a replaced then it would be subject to 20% re-stocking fee (re-stock a deective item?). Personally I get irritated by these companies who require you to pay for shipping to return a defective item, it's kinda like those great cell phone monthly plans at $29.95 a month which actually ends up being $45 a month after tax, fees and misc! Also I contacted Planar support for documentation on the displays and their reply was since it was an obsolete item, they had nothing on it... I was curious about what appeared to be a IR port on the front (a small square tinted block on the front. at first I thought it might have something to do with the touch pen but that has it's own plug in the back. FYI the moniter's model number is D5012TSP which I could find nothing on which I find refernece to on Planar's tech support form submission but nothing on their website, anyone else care to see if they can find anything on this model? 07-14-2004 07:26:55

RE:12 (modified 0 times) Rockhammer Profile | Email Ah...800x600 is more like it. That's about the highest you'd want on a 12 inch LCD. Glad to hear about the touch screen drivers and the screen condition. I am so tempted by this. It would make a nice replacement for the 12-inch Unisys/Keycorp I'm using in my carputer. What OS are you using? 07-14-2004 07:56:23

RE:12 (modified 0 times) BigDog Profile | Email I just hooked up what I could find on the workbench which was a Win95 200 MMX PC, I'm thinking about sticking a GCT behind it as I have old one that blew out the IR keyboard and had a bad DSTN LCD; I also have a couple of those "Barbie" computers which I may try but I think one of them has a dead video. I was flirting with the idea of making a GPS system for my truck but one of those TFT kiosk type units might be better for that. Personally I am not overly excited about the quality of what I have seen so far, I thinking about finding a replacement power supply and diagnosing the bad display myself as it will take at least two weeks to ship get a replacement and with my adult ADD, I may lose interest in it by then! 07-14-2004 08:24:01

RE:12 (modified 0 times) BigDog Profile | Email The LCD these are IBM 74H0700 which I'm pretty sure is a Sharp LQ12S01. I haven't been able to find a whole lot about, the sensor port on the front still has me curious as I believe it's a light sensor which automaticly adjusts the brightness and contrast as I found this: http://www.tridentdisplays.co.uk/products/electroluminescent/colorbrite.shtml There are no controls on the front to sdjust the contrast or brightness, so I assume my thoughts are correct about a ligt control. As mentioned before, there are no scratchss on the face of the LCD which after disecting on I found the touchpanel is glass and the actual LCD is very protected. 07-14-2004 12:11:01

RE:12 (modified 0 times) Rockhammer Profile | Email Thanks for the update. BTW, GPS on a "real" computer rocks compared to the pitiful dedicated handheld things or on pocket PCs. I travel a lot on business and wouldn't be without it. 07-14-2004 13:41:34

RE:12 (modified 0 times) Musicman38 Profile | Email Got my monitor in yesterday. I'm pleased as can be Luckly I had an old VGA cable in my surplus parts box. Plugged it up to my Windows XP computer and booted in VGA mode, and it works at 800 X 600 @ 60Hz, perfect for a 12.1 inch, and the screen is not the brightest, but it's TFT screen so thats as good as it gets. Had one or two dead pixels on it, to be expected for a used monitor. My Screen is perfect as can be for a TFT, and not one scratch on the surface screen.. Wondering if mine was ever used as a touch screen. BTW: Mine had a sticker on the front that said "NYMEX Service Desk" I hope to mount this unit in the wall, and use it as a controller for my HomeSeer home automation software. Now to get the touch screen driver installed from www.elotouch.com Has anyone installed the drivers yet ? Wondering if they will work on WinXP.. ~Phil 07-14-2004 20:18:54

RE:12 (modified 0 times) Rockhammer Profile | Email "Wondering if they will work on WinXP" One of my big questions at this point. 07-15-2004 05:42:07

RE:12 (modified 0 times) inx3us Profile Semi off topic, I have two 10.1" touchscreens, just the touch glass and tail. I am having a very hard time getting a reasonably priced controller(serial). Any sources for these or, if anyone here gets an unusable TS and monitor or somehow destroys theirs through excesive tinkering or a misplaced can of coke on the bench... lmk 07-15-2004 07:01:41

RE:12 (modified 0 times) BigDog Profile | Email Rockhammer - on the touchscrren with XP.... I am almost 99.99% sure that the drivers work under XP, The drivers I downloaded from 3M's site were the latest greatest driver pack which claimed support for almost all operating systems and they even support Linux with a different download pack. This is what I downloaded and installed for my Win95 system... TouchWare™ Driver, Release 5.64 SR4 http://www.3m.com/3MTouchSystems/downloads/drivers.jhtml Here's another link too which doesn't require registration with 3M... http://www.touchscreens.com/support-drivers-microtouch.html 07-15-2004 08:40:09

RE:12 (modified 0 times) Slowturn Profile | Email Well I've been following the thread for info and decided to order one today...Hopefully it will come in good condition! But I wanted to share this link for all those interested in making a carputer: <http://www.mediaengine.org/> It's a Windows based media interface program. Looks good. Later 07-15-2004 17:05:50

RE:12 (modified 0 times) omni Profile Big Dog & RockHammer I tried the 3M drivers with XP and they worked... BUT - As soon as I did the screen calibrate they stopped working! Not a software issue - uninstalled and re-installed and still didn't work. Tried a 2nd screen and it worked until I calibrated - then stopped working - seems to have written something to the controller that made it NOT work? How to reset and clear the problem? 07-17-2004 11:16:58

RE:12 (modified 0 times) Musicman38 Profile | Email Big Dog & RockHammer & Omni Mine just did the same thing. I loaded the 3M drivers on my Windows XP Pro, and everything seemed to work. Detected the Serial port and Touchscreen, and it was working, I then calebrated the screen, touched the points on the screen as they came up, they flashed indicating it worked, and then after the calabration, the screen stopped resonding to my touch. I uninstalled the drivers, rebooted , and reinstalled this time, the calabration would not work.. Must need to reset the monitor somehow.. Anyone have any ideas ?? I don't think its a compatibility problem with XP, as this is the latest drivers from 3M, and clearly states it works with Windows9X, ME, Win2K, and XP.. Any suggestions apperciated.. ~Phil 07-17-2004 11:52:11

RE:12 (modified 0 times) Musicman38 Profile | Email Bigdog, I now find that after installing the 3M software and trying to calibrate my own monitor in Windows XP it now seems to be stuck on 800X600 mode also like yours. I can no longer see any DOS or CMOS setup/startup screens, only until the Windows boots and the XP splash screen kicks in can I see anything. I can no longer change my desktop setting back to 640X480, now it only works in 800X600. So looks like we all need to somehow reset these monitors (If Possible) back to factory settings.. Somehow loading the 3M Touchscreen software, and running calibration, it has messed things up.. Also looks like your 2nd monitor is not defective after all, well hopefully not or we are all in the same boat. ~Phil 07-17-2004 14:35:36

RE:12 (modified 0 times) eBoyDog Profile | Email This is 'BigDog' - Something went funky with me login and I couldn't get logged in.... I don't believe there is no logical connection between the touchscreen controller and the LCD controller; The TS controller pulls power from the mainboard but the controller board for the screen is a separate board inside the display. Now what I do believe is that there some sort of "auto-config" module that controls the brightness and contrast, I'm going to do a little fooling around with my bad unit before I send it back. The one display I have had no issue with it returning to lower res, the only thing different is that I was using Win95, I will load it to a WinXP machin hopefully this evening and see the results. I really wonder if there is somesort of software control program or OSD control for these things, I was really disapointed that Planar totally brushed me off when I requested support. The actual monitor was made by CTX so I wonder if they have something out here in a similer branded model from way back (1997?). 07-19-2004 13:58:01

RE:12 (modified 0 times) Musicman38 Profile | Email Last night I was able to completely restore the logic on my monitor. I had lost the touchscreen after I tried to calibrate the monitor. Just use the 3M software, and run the terminal utility program. enter the command <Ctrl A> UT <Enter> The complete manual on the logic commands for this monitor are here 3M Touchscreen Reference Manual I was able to restore my touchscreen, and it now works in Windows XP.. Hope this helps.. ~Phil 07-19-2004 14:18:02

RE:12 (modified 0 times) Musicman38 Profile | Email This is the actual manual for the touchscreen. 3M touchscreen Maunal The line commands are explained in this manual. The procedures for resetting the monitor, and calibrating are here. ~Phil 07-19-2004 15:52:43

RE:12 (modified 0 times) eBoyDog Profile | Email The RMA folks emailed back, they claim the monitors should have included a VGA cable.... The Planar tech support folks emailed me back.... This product was built for Planar by CTX. We sold them to Digital Electronic Corp. They sold them to the NY Mercantile Exchange. DEC has the service contract with the Mercantile. Therefore, you can contact DEC for support. These were sold back in 1998. Therefore, Planar no longer support or have the documentation for the D5012 since they are more than 6 years old. Regards, Won Kauh Adding to this response....the touch screen drivers are provided by GunzeUSA (www.gunzeusa.com) but I myself have been unable to download them. It seems a reseller is selling refurbished units and we're trying to develop a better support track for them. Unfortunately the gunze driver is only supported up to Win 98 and Win NT (Win 2K and XP are not supported). There is very little we can do about that. Regards Dave McClure Planar Support Seems odd that touchscreen driver would have a effect on the actual LCD operation..... After looking at one of mine again I see that the actuall interface from the TS controller goes through the mainboard (I thought the only TS cabe connected into the TS pen port only; With the no external controls on the LCD, I wonder if control can be gained through the serial port? The angle I am guessing with is that perhaps the computer not only interacts with the touchscreen but also with the LCD controller. Anyone tried seeing what happens with just a terminal program hooked up to the serial port? I am kinda thinking that a special program might be required to access the actual LCD control, like a POS program of such, makes sense if you designed these monitors for industrial use and you didn't want users fooling around with the controls. FYI - These puppys were the cat's a$$ in their day with a list price of $2,995 in 1996 which was for the similer PV600 12.1" monitor without touchscreen. 07-19-2004 20:24:17

color (modified 0 times) boxybrown Profile Anyone have issues with the color? My display has a green tinge to it. 07-20-2004 09:57:18

RE:12 (modified 0 times) eBoyDog Profile | Email Same here, I believe it's due to a bad backlight or a weak power inverter. I was going to send one of mine back as it had a bad power supply and the tint was bad but instead I found replacement power supply at work (had to change the cord to match) and I found a replacement LCD on eBay for $30 which with the cost and time of shipping it back to SoftwareAndStuff; I should hopefully be in better shape. If the replacement LCD doesn't help then I'm going to replace the power inverter board. 07-20-2004 10:52:46

RE:12 (modified 0 times) Musicman38 Profile | Email eboydog, The display is for sure affected by the software /drivers, and can be programmed by them. May I suggest you plug in the serial port of the Planar to a computer, and with another monitor load the 3M Touch software, it has the utilities to reset the monitor, and change the properties using the built in terminal program that communicate directly with the monitor. I fixed mine this way, as I had lost my touchscreen and my planar was stuck in an 800X600 mode, so I could not see any boot up screens or anything else. Just a suggestion.. ~Phil 07-20-2004 17:53:17

RE:12 (modified 0 times) Musicman38 Profile | Email BTW: I don't know much about this www.gunzeusa.com site, but the 3M software I listed the links to in the previous posts works fine in all OS's, including Windows XP.. ~Phil 07-20-2004 17:57:11

RE:12 (modified 0 times) Musicman38 Profile | Email Here's the link to the 3M TouchWare User Guide Manual http://www.3m.com/3MTouchSystems/downloads/PDFs/19-224v26.pdf There are also many other Reference manuals on their website, that show hardware commands, and firmware commands. ~Phil 07-20-2004 18:08:03

Some more information (modified 0 times) RadicalDude Profile I received one of these puppies and it took me three days to figure out why it would not respond after a calibration. I eventually discovered that opening the Touchware Terminal window and issuing a <CTRL-Q><ENTER> causes the touch event messages to flow again. I wonder if the problem is really a flow control issue with the serial port? Perhaps software (CTRL-S/CTRL-Q) vs. hardware flow control ... hmmm. My particulars ... Planar Model D5012TSP Touchware 5.64 SR4 Windows 2000 SP5 The Touchware software indicates that I have a TP4 controller with firmware 2.20. I now have this baby running as a secondary monitor on Windows 2000 and it works nicely with the Homeseer Touchpad interface. Hope this helps. 07-21-2004 16:24:05

RE:12 (modified 0 times) boxybrown Profile So, will using the 3M terminal allow one to keep the monitor in 800x600, but still see the boot screens? Or does the monitor HAVE to be in 640x480 for that to happen? And for those using these for HTPC, are you going to connect the monitor directly to the HTPC and use it as a 2nd display? This is not really an option for me, as I have my HTPC in a closet behind my TV, across the room from my couch. It is frustrating trying to control it with the IR Airboard that I have, and the text is basically unreadable on my HDTV in the custom resolution that I have it set to for DVD playback (1776x988). What I would really like to do is have the touchscreen connected to a 2nd computer next to my couch, that would be used to remotely control the HTPC. Would this be possible to do with terminal services? I've never used it before, but want to know if it'll work before I go installing win2k server on the HTPC. 07-22-2004 08:03:22

RE:12 (modified 0 times) piperpacer Profile Boxybrown, Maybe this Airpanel would work better for you: http://www.compgeeks.com/details.asp?invtid=F-APV110-DOCK-SK6 At least you could hold it in your hand and it was built to take advantage of terminal services. It is not a cheap solution. 07-22-2004 08:41:56

RE:12 (modified 0 times) piperpacer Profile ... And an Airpanel review: http://reviews-zdnet.com.com/ViewSonic_Airpanel_Smart_Display_V110/4505-3174_16-20687764-2.html?tag=glance I don't have an HTPC but the Airpanel would appear to be an awesome remote. 07-22-2004 08:55:40

RE:12 (modified 0 times) boxybrown Profile Thanks for the suggestion. I've seen it before, and have definitely considered it. It would be an awesome remote, but I just could not justify the price. The portability would be nice, but it is not necessary, as I would be sitting in the same place when I need to use it. I already own this touchscreen, and already have a computer next to my couch for websurfing, so that's why I'm trying to make this work. 07-22-2004 09:11:42

RE:12 (modified 0 times) Musicman38 Profile | Email I still have not figured out how to get the default 640X400 to work so I can see my Bootup screens. It's stuck in 800X600 Mode.. Somehow originally the screen would auto adjust in bootup from 640X400 and then after Windows XP loaded to 800X600. So it's stuck now in 800X600 modem only, so I can no longer see bootup screens. Thats fine for now, as the touchscreen works prefectly in that mode. Works great for my HomeSeer Automation stuff. I also have a Viewsonic Airpanel Smartdisplay, it's awsume for remote control everything in my home, and wireless surfing the internet. ~Phil 07-22-2004 10:23:00

RE:12 (modified 0 times) Musicman38 Profile | Email If someone figures out how to change screen properties on the Planar monitor, please post this.. Mine is still stuck in 800X600 mode, and will no longer auto adjust back to 640X400 as it once did when I first got it. It stopped after I did a calibration. My touch screen works fine now, just can't see bootup screens. ~Phil 07-22-2004 10:26:12

RE:12 (modified 0 times) Musicman38 Profile | Email Boxybrown, My touchscreen originally auto adjusted like most LCD screens do, however after I calibrated it no longer auto adjusts. Likely just a command to change it back, just have not found it yet. 07-22-2004 10:29:18

RE:12 (modified 0 times) RadicalDude Profile My monitor shows the 640X480 bootup screens in the middle of the 800X600 display much like some laptops do.

RE:12 (modified 0 times) eBoyDog Profile | Email Dim-off color display fixed!! Replaced the LCD and now the color is bright and crisp. Found and exact match on eBay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=3492701139&ssPageName=STRK:MEWN:IT LCD I received was new, surface protector on screen, anti-static bag packed. payed $42 total with shipping and took a gamble that the LCD would fix it as opposed to sending it back for a RMA replacement and not knowing the quality of the one I might get back. 640x480 is still not working even after giving it the terminal commands; I still say the touchscreen and LCD controller have nothing to do with each other.... HEY CODEMAN!! Don't you work with LCD controller/Displays and such?? What's your thoughts?? The actual touchscreen is not part of the TFT LCD, the base plugs in the back and TS controller are only connected by the 4 lines. If you were email 3M tech support I am fairly confident that they would tell you the same thing. There must be some sort of control for the LCD and while it may interact with the same serial port line, I stick to my theory that drivers for the TX controller have nothing to due with the auto sync of the LCD resolution display. Now... what type of sensor is this?? Front of board Back of board Another view of the front My guess is that it's a infrared sensor like that on a TV... There are four componants on it, a transister, power LED, the sensor and the ribbon cable connector; the ribbon cable connects to the back side of the LCD controller board were you can see if you take the back cover of the display off, you can't see this board unless you take the LCD out. I ran the monitor without the ribbon cable connected and nothing including the inablity to display low res changed. Anyone out there have one of those learning TV remote controls? :) Also funny thing about the pictures, there appears to be a black appearance on the surface of what I am calling the square IR receiver but in regular light with your eye it's shiny and steel chrome. The camera flash brought out the blackish appearance. 07-22-2004 19:47:35

RE:12 (modified 0 times) eBoyDog Profile | Email Found this out about CTX's 12.1" monitors from http://www.atip.org/public/atip.reports.96/atip96.102r.html CTX began by offering monitors using 9.4-inch VGA LCD panels. They offered varieties using color TFT panels (from Hitachi, NEC or Hosiden), color DSTN panels (now discontinued; from Toshiba or Sanyo) and monochrome STN panels (from Sharp or Casio). They now also offer 10.4-inch VGA monitors, 11.3-inch VGA monitors and 12.1-inch SVGA (800x600 pixels) monitors. They include features such as touch screen, remote control, front control panel, and built-in speakers. The majority of their monitor sales are on a project basis, i.e., contracts such as a bank replacing all of their monitors at one time or a government institution wanting a large number of monitors over a specified delivery period. The best market for them so far has been in Europe, while the US market is not as good as they had hoped. CTX sold about 6000 monitors in 1995 and targeted doubling that in 1996. The shortage of 12.1-inch panels, due to a lower than expected yield, and to notebook computers eating up what supply is available, is proving to be somewhat of an obstacle to meeting this target. Ok, CTX did make 12.1" touchscreen LCD monitor with remote controls... 07-22-2004 20:19:15

RE:12 (modified 0 times) smee Profile eboydog/bigdog: Sensor definitely looks like an IR receiver. Maybe the remote brings up a configuration menu. This way only supervisors would be able control monitor setup, not the individual users/stations. Now, if someone can find one of the remotes it can be passed around the country so that everyone can "learn" another remote from it. 07-23-2004 05:42:33

RE:12 (modified 0 times) Rockhammer Profile | Email Good thought Smee. It would also prevent those pesky end users from messing around with the BIOS settings. The monitor could be programed to boot up in multi-sync mode for the first few times and then lock down at 800x600. Being unplugged from the power for a few hours/days/weeks could trigger a reset. 07-23-2004 09:58:20

RE:12 (modified 0 times) eBoyDog Profile | Email It is odd that I can't find any info on the IR or remote control, seems like there would be something out there, CTX apparently made them just for NYMEX but I would have to guess that if CTX made them on one company that they would have made them for someone else. They weren't prototypes so somewere there has to be someone out there who knows something about them!! Perhaps we should contact Samuel Gaer who is currently the Chief Information Officer at NYMEX or Allen Feryus who was Senior Vice President of Information Services in 1996. I thought I found Allen Feryus's resume on a web site a couple days ago but I lost the link. If an email address could be found then heck I would email them, what's the worse they could say? "No, go away little hacker!"?? Heck for that matter, email support@nymex.com !! CTX made the montiors, branded them with Planar's who in turn sold them Digital (DEC) which installed them at NYMEX. Look's like DEC (Digital) was eaten up by Hewlett Packard which in turn is now part of Compaq, I wonder if HP or Compaq has any support info on the monitor? I know nothing about IR controling, I might to dig in and see what's involved in hacking a interface out say using a palm pilot or such.... but without some sort on idea say what the IR remote can invoke, it might be a short trip and shallow hole. 07-23-2004 13:47:54

RE:12 (modified 0 times) eBoyDog Profile | Email As replacing the LCD fixed the one I had that was off color and dim, here is another eBay auction for a replacement LCD... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=42187&item=3494498273&rd=1&ssPageName=WDVW I can't say for sure if it might fix yours boxybrown but I believe I might get another as the one I replaced is better now than the one that worked. I can't vouch for the particular ebay seller as this was not the same one I got mine from but the LCD in this auction is stated as new and in a sealed bag. 07-23-2004 15:22:27

RE:12 (modified 0 times) Musicman38 Profile | Email I just got my second monitor delivered today, and I noticed that the screen was off center to the left by several pixels. Not a big deal, but if it had controls on the LCD it could be corrected. This second monitor allows me to see the DOS, CMOS and startup screens, indicating it has auto mode turned on. I dare not run the calibration program for fear I will loose auto mode like I did on the first monitor. My computer uses a SIS Video controller, and the video card software allows for the adjustment of brightness and tint. This does seem to work on the LCD as far as adjusting hue, tint, and brightness of the monitor. 07-23-2004 20:09:16

RE:12 (modified 0 times) Musicman38 Profile | Email BoyDog, Whats the quality of your monitor with the new LCD installed ? Is it really bright with vivid colors again, like a new monitor ? DO these LCD's get dim or washed out after years of use ? I plan on keeping my two monitors for a long while, so I may want to invest in the one you mentioned on eBay. Thanks, Phil 07-23-2004 20:14:03

RE:12 (modified 0 times) boxybrown Profile argh. I can live without the boot screens, but my monitor needs calibration! every time I calibrate it, I must go and reset it. 07-24-2004 08:11:30

RE:12 (modified 0 times) eBoyDog Profile | Email Yes, LCD's do go dim esp on old TFT's such as these; the stated life is something ten's of thousands' of working hours which usually equates to 5 or 6 years. As I have come to know with repairing notebook displays, if the screen is working but off color or brightness/contrast is off, it's the Cold Cathode Fluorescent Lamp (CCFL) and usually it's the easiest to replace the whole LCD but there are companys that just sell replacement CCFL's which allow you upgrade the brighteness of select LCD's. If there is no brightness and if you shine say a flashlight to the LCD and you can see the image then usually that's do to no power such as the inverter board(s) being bad; sometime a LCD will have two inverter boards and if you have half screen showing then the fault is one of the inverter boards. Sometime if the LCD has been subject to rough conditions the glass bulbs can break but most LCD's viewing surface will crack or break before the thin light tubes break (most bulbs are about the size of a thick pencil lead. The light sources are in a sense are just like the flourescent light bulbs in a office, they last a long time, use less power and as they age they lose their brightness of a period of years. I used to believe that leaveing my LCD monitors on over night and weekends was ok as there would be no burn in but in a work enviroment, turning your LCD monnitors off when you go home and back on when you arrive to work will more than double their life. http://computer.howstuffworks.com/question580.htm And yes, replacing the LCD did greatly enhance mine,I am very happy with getting an new LCD rather than send mine back for RMA replacement. Don't forget, these TFT displays are 8 years old if not older and I am sure they were used extensivly! 07-24-2004 10:13:30

RE:12 (modified 0 times) eBoyDog Profile | Email I heard back from CTX in regards to a support request on the PV600 display, they told me: Please call 1-888-289-6786, thats the company called Optoma, they should be able to help you out. Anyone want to call and see if there is anything Optoma can do? I have been busy at work and haven't had time to call, perhaps if several of us call they might give us access to some technical info. By the have the PV600 which is the LCD controller is what the PanaView 600 LCD monitor is based on, if you check eBay from time to time, you can find a 12.1" display up for bid. 07-30-2004 14:50:21

RE:12 (modified 0 times) eBoyDog Profile | Email Hey anyone out there??? Just fooling around with an old GCT mainboard that I wiped out the wireless keyboard on trying to add the PS/2 ports and it had a busted LCD so I made a VGA cable for it and hooked the puppy up to one of my Planar displays. The low resolution worked, so thinking I had my good one hooked up and wanted to compare the two, I hooked up the other; low and behold, both worked!! I am wondering if there is a difference in some video adapters? My GCT VGA I wired exactly as I have before (I soldered headers on GCT's for folks here and made up a bunch of the VGA out adapters for the GCT's) which I hookup VGA pins 12 & 15 which are for DDC Serial Data Line and DDC data clock line which some adapters support and others do not. I'm thinking the low res problem is related to the type of video adapter that is attached to the monitor? Still doesn't explain why the problem occured with the same computer but on two displays, I am not familier with the process that display use to determine the resolution when they detect a signel, Codeman would be the guy to voice his thoughts on this.... 08-17-2004 21:11:10

RE:12 (modified 0 times) DarkSideBlues Profile I wrok for a company that intergrates and services LCD touch Monitors. The controller you have with work with the 3M driver for most OS's. Under Linux, there is no seperate Calibration table for stylus / finger. If you are having major issues with the screeen refusing to operate folowing a calibration, open the Touchware control panel, go to the tools menu and choose Terminal Mode. From here you can restore the standard operating defaults of the controller with the RD command. <ctrl>+ARD. This will normally force the controller to load factory defaults and may require a system reboot before the touchscreen will be active again. The touch controller has no connection data-wise with the LCD controller. There should only be a connection from the controller communication cable to a power source and a 2 communication lines back to the host PC TXD and RXD for a total of 4 wires. It is also worth noting that with a TP4 controller, it may be worthwile to perform a 25-point Linerization as the NOVRAM location holding this information was easily corrupted. Open the Tools menu, choose the options button, followed by the advanced button. You should see a series of white boxes along the right side of this window. Place a check mark in the enable linerization box and close back to the tools menu. This will allow you to linerize the touchscreen to the LCD with a 25 point target set. Once you finish this, do not click Done on the windoe that pops up, rather click continue. This will bring up a 16 point verification screen that will allow you look for major defects in the touchscreen. Anything greater that 1.5% may not be able to be compensated for with a normal calibration. I may also be able to get my hands or some of the TouchPen Stylus components if you are interested (Free of Charge, just shipping) 08-25-2004 11:01:58

RE:12 (modified 0 times) zedmeek Profile | Email Hi Phil - I was just wondering if you might help clarify a few things about these. I bought one locally here in Santa Clara, and merely wanted to use it as a cheap thin server monitor. Sure enough, stuck in 800x600 .. or I guess it is. The backlight stays on though during the post and BIOS runs .. so it seems to be a 'sync' issue, or something (unlike when it goes out of range which basically shuts the monitor off). A few things: 1) Can I just go to radio shack and get a serial cable to plug this into? I assume I don't need a null modem cable .. or do I? 2) Will the software correct the display mode funniness? I plan on trying to get the software working on my XP laptop to reset it or whatever. Guess I just wanted to try to get it working before i settled on way too much in-store credit :/ thanks in advance. 10-04-2004 23:18:32

RE:12 (modified 0 times) Programmer65 Profile | Email I know my problem isn't breaking news so I hope it's OK to reply to this thread as others have done. I have received one of the Planar 12" monitors and am having problems with it. At first, it appeared to me that the thing just wasn't responding to touch at all. I figured it was a bad monitor. Then I saw the message posted above about sending a Control-Q to the monitor. I have found that if I use the "TouchWare" software and use the "Terminal" to talk directly with the touch screen and send a Control-Q, the monitor starts working. However every time I calibrate the monitor, it reverts back to not working (not responding to touch at all) and I have to send the Control-Q to make it work. And furthermore, when I turn off the monitor and turn it back on, I have to re-send the Control-Q. As long as I don't have to calibrate often, resending the Control-Q after calibration is not that bad but I can't do this every time I turn the monitor off and on. Any ideas on getting this to work consistently even after powering off and back on? I think the settings for the com port should be 9600,n,8,1 and that's what I'm using on my Windows 2000 com port. I have also sent a "RD" command to restore defaults successfully and still have the problem of having to do the Control-Q in the terminal mode to get touch working again. Any ideas on what to try to get this monitor working consistently through a power-off and power-on cycle? 10-06-2004 13:24:34

RE:12 (modified 0 times) mamemaker Profile I got one of these monitors a couple of weeks ago and it works ok. Screen colors are ok for my use. The calibration of the touch screen is off a little (even after several attempts to calibrate). Using for a home touch screen Jukebox system -- having problems finding a good software package that fits my needs. I have the same problem with having to go through the terminal window after each power down or calibration. I've just come to the conclusion that I need to leave the monitor always on. I can power down the PC and leave the monitor on and it will still be in touch mode after I re-power the PC. I've tried to come up with some batch file or utility program to send the reset command to the monitor on the PC power up - I have not been successful with this yet - any help here would be appriciated. Using XP home. 10-09-2004 10:33:21

RE:12 (modified 0 times) chillywilly Profile Hello, I recently bought one of these and I think I either need a replacement LCD or an inverter. I read in the thread that some people replaced the lcd, could someone tell me what the replacement part is? Also I'm trying to find an inverter but I am having no luck in locating a part number for the inverter. Would someone know what I could replace the inverter with? thanks, ChillyWilly 03-09-2005 22:54:13

RE:12 (modified 0 times) eBoyDog Profile | Email Give a day or so I will confirm, I believe I still have my old one but these particular LCD's were used in a whole lot of notebook displays, using eBay I would stand to believe you could cross reference it to different notebooks it was in and find a good inverter to go along with it, might require a little splicing but the basic function would still be there. 03-10-2005 14:51:48

RE:12 (modified 0 times) eBoyDog Profile | Email The LCD that I replace was a model 7H0740 which I could find no example but I would advise that you take the old one out first before getting a replacement as there could be other models in certain displays. 03-11-2005 14:20:51

RE:12 (modified 0 times) chillywilly Profile Hello, I took my unit apart the other day and I could not see how to separate the lcd from the board. Anyway last night I plugged the unit to my laptop and I did get some video. The only problem is that the backlight did not turn on. So I'm thinking that I need an inverter or backlight. Would you happen to know what inverter I can replace the original one with? If I need to replace the backlight could you give me some pointers on how to take it apart? Thanks for all your help. ChillyWilly 03-11-2005 15:20:09

RE:12 (modified 0 times) eBoyDog Profile | Email Hey, I had a typo on the lcd model, the model was 74H0740 Just like this... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=31569&item=6745069103&rd=1&ssPageName=WD1V I believe the backlight light tubes can be replaced as I have seen such esp for higher priced LCDs but the cost might be an issue and you have to basicly take the the LCD panel apart; I considered that option too but found a complete replacement much cheaper. I don't recall how the LCD comes out but after removing the mainboard, I believe it just pops out, I see from the old LCD that there might be screws in the four corners, the touchscreen is stuck to the lcd by double sided adhesive which I do recall I used a razor blade to seperate it keeping most of the adhesive on the touchscreen side so it was no issue gettingto stick to the new LCD. From the eBay auction, the seller claims that this lCD was used in: Acer AcerNote 970-series Acer/TI TravelMate 7000, 7100 ACTEBIS TARGA TN 549 PROII w/PIII processor Dell Latitude LM TS30GI (p/n 97701) Unisys Aquanta EN Nan-Tan laptop (~1997) Planar PV600 (LCD display) CTX Panoview 600 (LCD display) possibly Dell Inspiron 3000, 2500, CP, CPi(ST) possibly ChemBook 2600 So using that, if you need a inverter board, one might be able to track down one of those to find a used board and possibly a replacement LCD. 03-12-2005 07:13:34

Relevant info for Planar 12.1" LCD Touchscreen (modified 1 times) dsrnkc Profile Hello all! My name is Daniel and I would like to help you guys and girls out with some of your problems with this screen. First question I would like to address is the power connector. _____---_______--- _fg1_/.__\__fg2_/._.\ ____/.___.\____/.___.\ ____\._|_./____\._|_./ _____\---/_____\---/ (I would like to apologise for the lines, This posting program removes extra spaces. Figure 1 is the power port on the monitor (female). Figure 2 is a normal PS2 plug (male). To make a useable power plug, simply break off the upper left pin on the PS2 plug and viola! Instant power plug! The connection pins are as follows (looking at the female port on the montior). Upper left and middle left = +5v @ 2-2.5A Middle right = +12v @ 1A Lower left = common (GND) for both voltages Lower right = No contact The next question that I would like to address is the dimness of the display. CAUTION!!! For the following steps you are going to have to disassemble your monitor. I am NOT roesponsible for any damages that may occur to you or your monitor. Example: while i had my monitor appart I forgot to shut it off before unpluging the high voltage plug to the lamp. The high voltage started to (literally) burn my skin. During the manufacture of these particular lcd screen they had the bright idea that they would use an acid base paper to further diffuse the light for a more even picture. Over time, the highly acidic paper started to brown and get brittle. Thus resulting in a dull, dim, out of focus, and off color display. To remedy this simply (carefully) disassemble the lcd panel and remove the browning paper. It is located under the thick plexi-glass diffuser. I say carefully because you cannot repair the connections to the glass and they do break AT THE SLIGHTEST TOUCH!!! After you have removed the paper you may replace it with new diffusing paper or (this is what I did) simply put the thing back together without the paper. It is very difficult to tell that anything was removed by looking at the screen. After I did this the display was as bright and as crisp as the day it rolled off the factory lines. Have fun!! Viva la CARPUTER! 05-18-2005 01:33:02

RE:12 (modified 0 times) chillywilly Profile Hello, I have one of these monitors and I have successfully made the monitor useful using many of the suggestions posted in this thread.
