iPhone 5s will not power on
Recently the screen of my iPhone 5s started to look strange - it had horizontal white lines across the entirety. I disassembled it in order to clean the connections, but when I tried to turn the phone back on, it ceased to function entirely. The screen would no longer turn on, and it no longer vibrated or made any noise. The battery gets warm when I charge it, and I can hear the hard disk.
Things I have tried:
-disconnecting the battery and holding the power button
-hard reset
-restore
-checking the screen connectors and making sure they were placed properly
-"charging" overnight
If anyone thinks they can diagnose the problem, any input would be greatly appreciated.
Is this a good question?
