Hi, we have an LG 32CL40. After watching TV for about 45-60 min it suddenly turns off. Then when we try to turn it back on agaIn it lasts 5 seconds before turning off. If we leave it for a long while we can start this pattern again. It first happened a week ago. Just tried using the TV again today and got same results. Does anyone have suggestions on how to fix this?

Yes it seems like the Power supply unit in the TV is overheating. Try cleaning the vents in the back of the TV with a brush, and then blow out the rest of the dust with an air compressor. This may be a quick fix.

Agreed.

I recommend removing the back panel if at all possible if you are going to try blowing out the dust. Canned air is sold at most hardware, auto parts and computer/electronics stores. A Vacuum is another idea. Be aware that if you don't know what you are doing you could break something as you remove a panel.
