Replaced cracked screen. Ipad now doesn't turn on.
I have attempted a repair on an iPad Air with a cracked screen. Prior to starting the repair, the iPad worked with the cracked screen. After the repair, which went flawlessly, the iPad would not turn on. If I connect the iPad to iTunes, iTunes recognises the iPad but says that the iPad is locked and must be unlocked before doing anything else.
At this point, I assumed I had purchased a dud digitizer on eBay and ordered a new one from ifixit. That arrived this morning and I repeated the repair procedure... with the same result.
At this point, I am assuming that I must have somehow damaged the LCD screen during the repair. Before I go ahead an order an LCD screen though, I would like to know:
- is that a reasonable assumption?
- are there any tests I could perform to confirm this diagnosis?
