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.
So you get no sound from any input, is that correct?If you look in the tvs settings menu, under the Audio section, you should see a Speakers setting, make sure that is set to ON or to TV.
Does that help?
