my iphone, having this problem after battery replacement, i have tried disconnect, clean the connectors and reconnect all screen ribbon connectors but it’s still doesn’t work…
This is usually a bad screen and possibly caused by damaging the flex. It can also be caused by pry damage best to rule out screen first. If it is still there with new screen it’s possible going to be a board issue caused by pry damage. Cheers
