black display screen after reassemble back iPhone 4
I replaced the power button cable and reassembled the phone. But now i only get a black screen. I hear a ding sound after plugging in the charger so I know the battery is charging. I can also connect the phone to my computer and have it be detected by iTunes. I took the phone apart and rechecked all the connections, and still nothing. Any idea what could be wrong
Is this a good question?
