No sound on this older LG TV
Power flickered and reset all TVs, clocks, satelite receivers, etc. Now I have no sound on my TV. Tried all of the suggestions. Reset TV several times. No sound on my sound bar or the tv. I imagine I had a power surge as we heard a small spark when power came on. Is there a sound card or do I need to replace the circuit board? How difficult is it? Hate to discard as it has a great picture.
