Gray lines on LCD after screen replacement, now iPad wont power
I cracked the screen of my 4th gen iPad and decided to attempt the repair myself. After a good 2 hours of painstakingly removing the shards of screen I finally connected the replacement and decided to test it before completely reassembling. When I first powered on there was grey lines running across the screen so I powered off and rechecked the digitizer and LCD connections - all looked fine. Powered on again, same thing happened. Disconnected LCD and digitizer a second time and tried again. Now my iPad wont power on at all. I've tried a forced reset by holding down the power and home buttons, nothing. It seems totally dead. Tried to restore from itunes but due to the new iOS 7 upgrade, I need to first disable Find iPhone on the iPad - can't get in to the iPad to do so. iTunes at least recognizes the iPad and find iPhone says that my battery is still at 57% so its definitely not an issue with charge. Not sure what the exact problem is and would really appreciate some help on what to try next. I'm guessing I accidentally damaged the LCD and I will order a replacement but given that the screen lit up to begin with and is now unresponsive I fear I have caused some other damage? Thanks in advance for your help.
Ist dies eine gute Frage?
