Please I have a 42in., Sony television now for a few weeks while watching something the volume will just go nothing , right now I have to switch it off then switch back on and the volume is working I have gone onto settings where it all looked ok , I simply am at a loss any suggestions would be welcome thank you.
When I first bought our TV there was a fault the company that I bought it from came out and inserted a SD card ( I think) and did something which sorted out problem and has worked fine since.
