LG TV 39LN5400 keeps restarting after about 30 minutes of use

I have a LG TV 39LN5400, and yesterday it began restarting after a few hours of use. Today it only took about 30 minutes and it started acting up again.

I've owned for about 2 years, and didn't have any major problems with it until now.

Do you have any idea what the problem could be and how I could fix it?

Answer this question I have this problem too

Is this a good question?

ionutlucaci, sounds like you are having issues with some bad caps on your power board. Check all caps for domed top or leaking electrolyte. Post some images of your TV boards with your question. that way we can see what you see.

I opened it up, blew away all the dust (not much of it) and disconnected the power cable between the power supply and the mainboard (on both ends) and reconnected it back again. It's been running ok for the last two and a half hours. If it starts acting up I'll open it up again and post the photos.

Thank you very much for your answer, I appreciate it a lot, I'll keep you posted!
