Display screens only white

Same thing happened to me and I'll try to open it to see how if that is the case.

I'll post later, once it's done.

Same problem. Reseated connnectors 1, 2 and 5 and software restore to no effect.

I'll do a further teardown when I get time and post the results here.

thanks

Similar problem: iPhone 3GS : white screen with a light grey line.

Able to do reset with hoding power and home button.

Able to on-off.

I am able to connect to iTunes. iTunes recognize the phone

was able to do backup.

Tried factory default.

still white screen.

I will try to open it and look into cables. hope it is only lose cable.

thanks

How did you go? I have a white screen as well, after disassembling to change the battery, then the battery put it into a restore loop, changed to another battery, nothing, put the original back in, now itunes recognises it, and have done updates, synched etc, all good there (wasnt when i had wrong battery in). But now I have a white screen, it beeps, vibrates, but white screen, which connectors are responsible for the screen? 1,2,5? nothing seems to be loose, I have taken it apart again, the only cable i have trouble with is 3, not sure if i have it in enough. After doing a hard reset, i can only get the phone back on if i plug it into pc.the white screen displays then goes to sleep mode- black screen.
