Let me know if this is the wrong place to post tablet questions.

Customer did his own digitizer replacement. Now, backlight only works with Apple during boot. Image is still there and device is on setup screen as he apparently restored it.

Replaced LCD and digitizer.
Replaced LCD connector and backlight filter as they were a bit chewed up.
Device not go into DFU mode even though lock and volume buttons do function.
ZXW has no diode reading values yet and there are no schematics that I can find so far.

Has anyone seen one like this?
