Here's some simple things to try, just in case, but might be something harder: https://www.youtube.com/watch?v=gysJRUcAmTMComment

If anyone has special knowledge of this model they can probably help too, here's some tests to try: with tv unplugged from power unhook cable from powerboard to mainboard at powerboard, plug power cord into powerboard, see if backlights come on and stay on. If it passes that test, plug that cable back in, unhook cable from mainboard to driverboard (which is at the top in the picture) at the mainboard, turn tv on, give it a minute, see if you have optical port lit red and listen for a tone/chime from the speakers indicating tv is turning on. Each time a cable is unhooked or hooked back up, make SURE tv is unplugged from power. Do tests report back.Last edited by nomoresonys; 02-11-2025, 11:15 AM.Comment
