Hi, the tv is only about 2 years old. It does not do this
Immediately when switched on but after about 1/2 hr or so.
Hi, The sound bar appears on screen and then you can see it going slowly down to zero. Occasionally, I have been able to use the remote to get the sound to go up again if it hasn't gone down to zero yet but usually its already at zero by the time I have noticed. Sometimes I can then use the remote immediately to increase the sound but most of the time I have to leave it for a few minutes to be able to use the remote to increase the sound again.
I am at work at the moment so cannot act on your suggestion until tonight.
I will respond in the morning. Thank you
Sorry that I have not contacted you earlier today but I have been in back to back meetings.
I did all you suggested last night and thought it had worked. However about an hour later the problem re-occurred. I tried the process again last night and again this morning but I'm afraid the problem is still there.
