how do i replace former gooped bios socket

So I got a brand new i-opener a year ago from circuit city before they stopped selling them and shelved it after taking it apart and looking it over due to working 100 hours a week for a while.

I finally got around to playing with it last month. After MANY unsuccessful attempts trying to get into QNX to flashed my gooped bios, I decided to chip off the goop and drop in a new BIOS from badflash so that I could hook up a HD and make it a useful box. In the process of slowly and carefully removing the epoxy while watching TV for 2 hours, I did a decent job up until I cracked the bios socket. I can't get it to boot anymore. Not with my badflash bios and not with the original bios.

I'm pretty sure the socket is the problem so I want to replace it. Can anyone provide any clues on how to do this for someone (me) who hasn't soldered anything at that small a scale before? I've soldered large wires and things together, but never a socket onto a motherboard. Is there anywhere where I get it done professionally for a decent price?

Thanks in advance.

First, try using a tie-wrap to tighten the socket up after putting the bios in. This has saved some people the problem of replacing the socket. Also, do not push the bios chip all the way down into the socket. This has been covered before. Use the search function and you should be able to find more.

You are probably better off trying to repair what you have. If all of the pins of the socket are still soldered to the board, you can wrap the socket with a tie-wrap using a needle-nose pliers to tighten. Be careful not to apply any shear stress to the socket when doing this; using a twisting motion with the jaws snug to the head of the tie-wrap.

You may have bent inward a contact pin in the socket. If so, use a sewing pin to pry them out. You may need to put a kink at the end of the pin to get better leverage. This is also a good time to inspect for any epoxy flakes that may have become lodged in the socket.

I would advise against replacing the socket unless its your last resort. It is difficult even for veteran SMT repair people. If you do decide to do it, be care removing the old socket. Its very easy to rip up a pad off the PCB. First, cut away the inner plastic web at the base of the socket being careful not to cut any traces underneath. This will allow better working room for removal. Then, one at time, desolder and bend up the pins. Clean the pads with solder wick. Carefully place the new socket, tack the corner pins with solder making sure that the placement is correct. Then carefully solder the remaining pins.

There is quite a bit of technique involved, you may want to practice removal on a scrap assembly first. You will need a good soldering iron with a sharp-pointed tip and fine gauge flux-core solder.

Good luck!

Tie wrap didn't work....

Looks like it's going to be some pretty serious soldering for me.

I'll let you know how it turns out when I get to it, but it'll probably take a couple of weeks...Anyone else have tips, please post them soon.
