Hi Forum Friends I have a phone to repair, the customer says he dropped on a carpet and since then the screen keeps flickering.. I am guessing loose cable or damaged assembly? Any ideas
You can try to tear it down, disconnect the LCD screen flex cable, reinstall it, and check if the problem is solved or not. Otherwise, it may need to replace a new LCD screen. Witrigs has released a video on Youtube about the Samsung Galaxy J7 LCD screen replacement video. Maybe this video will help you.
