Facing TV Problems? Ask a TV Technician.
I'm reviewing your details and will reply shortly.
Offhand that error code on an LG set indicates a software issue on the "Mainboard" of the TV- and generally requires replacement of that component to fix the issue.
Please try those steps and send a reply back.
Are you able to get the set to power up normally? If not, can you get the MENU to display if you press MENU on the original LG remote?
Okay just to clarify- is the programming also on the screen in addition to that message?
Are you still with me here?
