I have a Panasonic TV that has great picture but no sound after a lightning storm. I just had a regular round coax between it and the Directv box and I had a DVD player also plugged to TV but I had all of them plugged in to a surge protector bar. I've tried leaving it unplugged for hours and I checked that the speakers are on, cables connected, etc. but still no sound. If I get a HDMI cable do you think that would maybe work to bring sound? I saw a post saying that they're just using AVI right now. What is AVI? I don't know anything about electronics as you can probably tell!! Thank you for any help you can offer!!
Also, if I hook it to some other speaker system would I have sound through that?
