Hi all, sorry for my weak language .. I’ve got iPhone 6 blackout screen after disconnect cables . I was trying to replace my broken lcd but when I pushed power bottom my iPhone not showing anything . I tried to reconnect old lcd and I’ve got no result. iTunes recognised my device which means the problems with the screen cables or something in related to the screen . thank you in advance for your help
Sounds like a blown backlight filter if the old screen had display before. You will need to take the phone to a microsoldering technician to get the backlight filter replaced.
So I’m going to just throw this out there because it doesn’t seem to be covered when you plug it into iTunes does it show that your phones in recovery mode or does it show that your phone is on? If it shows that your phone is in recovery mode have you tried a hard reset? Also have you disconnected and reconnected your battery after the screen replacement? I’ve done thousands of iPhone 6 screen repairs and I’ve never once blown a backlight. If this is an iPhone 6s it’s a different story. But an iPhone 6 it’s highly unlikely that it’s a backlight filter.
