It is the tv where the sound goes off from. Yes the problem occurs on all input sources.
Expert:  Shahid replied 12 months ago.
Thanks for the info.- So problem occurs regardless of what video input of TV is being used, like HDMI or Scart or AV etc, is this correct?- How old is it and how long it have had the problem?
Customer: replied 12 months ago.
Yes and about 4 years old
Expert:  Shahid replied 12 months ago.
Thanks for the info, this kind of problem occurs due to failing sound processor chip, its number would be TPA3113D2 and replacement of sound amp chip will help to resolve the problem. I'm sorry it is not any reset or wrong setting problem but hardware related failure, chip replacement on circuit board would require proper soldering tools and good expertise. I trust my input will help you out. Please feel free to respond if you have any additional questions.Shahid.
