So no sound either with other inputs like a DVD player?if so then that confirms the TV is responsible so to begin with can you please re-boot the TV by unplugging the TV from wallpower wait 5 mins then replug back in again, let me know if there is any change thank you

If you see any messages particular ones regarding phone call facility that is not sent by me but the site, I do not use this facility myself so if you do elect for a phone call it wont be me but another tech who will ring, I only use the text method to troubleshoot.

Let me know please

I unplug the tv and it does fine for 10-15 minutes then cracks and pops and sound goes off again.

OK if you are sure it does this with other inputs like a DVD player or similar then the TV has a bad amplifier, this amplifier is located on the mainboard and its this board that will need to be replaced, do you think you can do this work yourself?I will provide all the relevant info for you to do that, just to emphasize this is a plug in board.

If something like this is not your comfort then you will need a tech will locate a tech in your area

Let me know please if you can do this or need more help
