Screen powers up but goes blank?! LG 47LN575V
Hi all… I think this issue is common from wheat I read but I’d like to attempt to fix it myself, I’m fairly savvy but what I would like to know is the likely cause and what parts to get to replace? I’ve had the back cover off and inspected for anything obvious but nothing!
ANSWERS:
@baz7 let us know if you still have sound or if that gets lost to. <asure the voltages from the power board to the main board as well as to the backlight LED’s. In a darkened room, shine a flashlight beam against the dark screen (if you still have the sound of the channel) and see if you can make out shapes etc. If so it is the backlight. LG is having issues with backlight arrays. If not you will have to check on the main board as well as the T-con board.
