Samsung Galaxy J7 Prime G610F Display has connected the motherboard with a cable connector. If your LCD is not working, you obviously have to check if a faulty LCD is not causing this problem. If the LCD is okay then check the LCD connector.
Already been tried to replace a new replacement LCD screen and new flex cable wire and nothing happens but the display problem still exists like black screen display, blue screen display, white screen display, garbled and saturated screen display.Before you may proceed, you need to make sure first that the flex cable and the LCD are working fine or you have it tried with new replacement installed but nothing happens.
