No backlight and LCD replacement didn't fix it.

文本:

-My iPad2 was dropped. It worked fine, despite the digitizer glass being shattered. i carefully disassembled and installed a new Digitizer. Before sealing the digitizer in place, I tested the unit. I discovered that the LCD backlight was not working. I reseated all cables. No change. I inspected the iPad for any visible damage and found none. I replaced the LCD with a known working unit—and there's still no backlight on the iPad.

-What else could be wrong?

+I've been working on an iPad 2 that was dropped. It worked fine, despite the digitizer glass being shattered. I carefully disassembled the unit and installed a new Digitizer. Before sealing the digitizer in place, I tested the iPad. I discovered that the LCD backlight was not working. I reseated all cables. No change. I inspected the unit for any visible damage and found none. I replaced the LCD with a known working unit—and there's still no backlight on the iPad. What else could be wrong?
== Update ==
I have a third broken iPad coming to my department for repair. This time, I am going to let the battery drain 100% before anything is disassembled.

Folks, I appreciate your time posting:
1) Disconnect the battery.
-
2) Reset iOS.
These things have been discussed here at length and have not resolved the problem. My iPad issue is still not resolved.

-As I reflect on my disassembly, I have considered that I did something different the second time around on repair. The first time, I used a plastic scribe to release the LCD cable from the logic board. The second time around, I used the mini screwdriver from the kit to pop up the retainer. Reflecting on my actions, and knowing better, that probably created a short across contacts and damaged the logic board, despite my being careful. Of course, I am just guessing, but that was a difference between the two repairs I did. The first iPad repair being successful—the second, not so successful.
