Digitizer not working but lcd works fine
A cstomer brought me a damaged iphone 4 screen to replace. Lcd was badly cracked and there was no response on the digitizer on the "original" damaged screen.
I assumed this was just a result of phone dropped and cracked screen
replaced the digitizer/lcd assembly and phone booted fine. Just no response from digitizer still. Tried 3 other digitizer assemblies and still no response from digitizer.
Tried a hard reset. Board does not appear to have any damage to it. And the connector on board seems normal.
Is this a good question?
