TV Problem. Have picture but no sound.?
-
I have a Sanyo LCD TV. The sound worked when we went to bed but the next morning we had no sound. I have tried multiple things listed below 1. Checked mute (not muted) 2. Changed HDMI ports on back of TV (no sound on any port) 3. Tried headphones (no sound still) 4. Changed over from a HDMI cable to regular red, white and yellow cable. (still no sound) 5. Unplugged Direct TV box and just tried using DVD player (no sound with HDMI or reg. cable) One would think, ok the sound is out on the TV and it needs to be fixed or replaced. The only problem that I can't explain is when using the IMPUT button on the remote control, there is sound coming from "03" which I am guessing that is the regular antenna channel. When I switch it back to HDMI, no sound again. Before buying a new TV I want to make sure that its not a simple fix. Whoever can explain this one to me will get best answer and a ham sandwich!
