Hi. Just got an email about this.
I answered the questions the same day but have heard nothing since.
I wasn't sure my reply had sent the first time so sent it again.
Bought the tv about 12 months ago, give or take.
There was no storm and as far as I know there was no power outage.
Set has been fine since bought it. No problems at all.
The power light goes off completely.
After I sent my first query the tv had the problem for about an hour then was completely fine. Then last Sun it started doing it again. Lasted about an hour and was fine again and been ok since.
Many thanks Aric. No not what I wanted to hear lol but at least I know now.
I'll dig out the receipt and give LG a call.
