Slide detection no longer works

I also posted this over on xda in an effort to broaden the audience that may be able to help.

So my phones earpiece began to cut in and out, which I found to be a chafed and broken flex cable. No biggie, I ordered a replacement piece and waited for it to show. As I waited the phone began to get worse, I lost the earpiece entirely, the leds stopped working as well as the sleep button. The screen, now only able to be woken by sliding, would not come on when slid out, but only once it returned..also the screen would shut off when I would slide it out again.

I have seen disassembled the phone again and installed the new cable and all is well, with one exception. The slide function of the screen no longer works, period. It will not wake, it will not rotate, and the keyboard doesnt illuminate unless I press a key. I have been through this phone 4 more times now and I simply cannot pin down exactly what tells the phone that it has been slid. I have heard talk of magnets, but found no sensor or magnet, I saw small contacts..that are all functioning properly. There is no cable or connection to the screen portion that connects to any sort of switch that I can see.

Does anyone know what triggers the slide?!

Which rom are you using? If you have tried the shipped rom or you are on it now then we can eliminate a software problem.

Could there be a missing or bent pin in the ribbon connector?
Maybe the g-sensor has something to do with it.

Ive been running the same mightyrom for the past few months. This is a "just did it, now it doesnt" type thing.

The mechanism is definitely magneticcally driven. There exist a slight magnetic field near the "left" hinge when the keyboard is open. This is unrelated to the speaker which is nearby. There have also been problems with magnetic holsters screwing up the TP2 sliding mechanism/sleep mode. Do you or have you used one like that before?
