I have a three week old 32 inch flat screen HDTV flat screen. I hooked it up with not problems and have not had a problem until I came home from a trip. I turned the TV on and there is no audio. I turned on my DVD player and played a DVD and there is volume, but I cannot get the volume on my TV when watching cable. I unplugged the cable plugs, but nothing has worked. Any ideas?
We have the same issue with our Insignia HDTV. The solution (which is not a solution) on our set is to switch the input to any of the other choices then switch back to Component 1 which is where the cable box is input.
Usually a pwr surge has zapped the signal panel which has switching circuits for cable audio/video...john
