Question about Televison & Video
I have tried unplugging it from the mains for a few minutes but once it's powered up it has the same problem. I have checked to see if there are any odd timer settings (although I don't believe these would be the problem). If it has been unplugged for some time it stays on longer which make me think it may be a thermal problem - something overheating?

Good Luck

your problem is no doubt in the stand by circuitry You will have to trouble shoot your set as this is a thermal issue and you will need to do the testing of the various components while it is experiencing the trouble to find the problem. Let me know if you wat a manual. I can provide a link where you can get one .

I still have that problem. I calle Mfr and also spoke to repair shops recommended by them and they said they estimate a cost of 300-400$ or so approx. I am waiting to buy a new LCD which could be few 100 more but at least dont have to live with the old one and keep spending money...
