Facing TV Problems? Ask a TV Technician.
Hi, I'm Nathan.Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.
Look on the back edge of the tv, at the very bottom, in the center (feel around from the front and you'll get it) for a single round button there, press and hold that for 5 seconds, does that do anything?
