Thanks for the info.

- So power light on TV doesn't blink in specific pattern and stays solid?

Power light is a solid orange if I timer recordings set or solid green if no timer recordings set

OK, do you switch Off the TV from main power/ cut the AC supply to TV or press power button on remote to get it working again?

Customer: replied 1 year ago.
No response when using remote.
I use power button on tv to switch off and then on again

Thanks for the info, it seems main board internal failure that occurs when heat buildup in main processor chip so TV doesn't show picture nor sound but stays On (power light status), when turn Off the TV for a while that resets the main board and it start working again until the heat build up again.

I am really sorry about this and you are going to have to return the TV to have it replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you. If TV is out of warranty then main board replacement would cost around 100+ Pounds. I hope these info will help. If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page.
Thank you.
