my phone’s screen went all black but it was still on so I disassembled it and put the wire back the screen was back but with no sound so I disassembled it again and paid more attention to the speaker wire when done the phone won’t turn on at all but when charging the battery logo appears (excuse my English I know it sucks ) what should I do now ?
Check the power button, it plugs in via ribbon cable into a slot connector that has a locking mechanism. Maybe it isn’t connected in fully. This is what the power button ribbon cable / flex looks like:
If it comes to worse, could be the socket / pins of the power ribbon cable socket damaged.
