Can anything else be done to fix the white screen on a 3G besides restore/upgrade and DFU/restore?

It sat in a box for ages, so was completely dead. I plugged it in to charge, got the white screen (oh noes). Left it like that for a bit.

Tried a home+lock 15 second reset, screen went black, came back up to white.

I did the upgrade->4.2 first via iTunes (latest, 10.6.x), no such luck. Still a white screen. So .. Ok, maybe the firmware didn't overwrite something, let's do a DFU update.

Put it into DFU mode (took a couple tries, but only like 3 tries, I promise :p) and saw the DFU on iTunes and Windows 7 system tray, so I know I loaded the DFU mode correctly.

Did the restore, still a white screen. Note: since the 4.2 upgrade I can work it blindly, for things like swipe to unlock, press and hold power for 3 seconds, swipe to shut down. So I know the logic all works, it's literally just the white screen.

Any last takers on tips before I consign it to the bin? (give it back to my buddy who had it in a box and thought it would work)

If everything but the display works, you can try adjusting your display cabling and/or replacing the display unit. On that model, the digitizer is not tightly coupled to the display, so you can get a piece on ifixit. I remember once breaking the display on my third gen nano. It went white. Probably a defective display, but nothing that can't be replaced.

Before messing with it, I'd definitely give it a shot at the Genius Bar, if you're local to one. They have diagnostic tools and such.

no genius bar locally, and for the effort of getting replacement parts I'll give it back to my buddy and thank him for the offer of the loan. – jcolebrand Jun 17 '12 at 17:59
