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.
