I have a Samsung HL-S6165W 61" DLP TV. About a week ago, it shut itself off. Since then, you can power it on and it will play perfectly for about 15-20 minutes at which time it shuts itself off. There are 2 green lights and a red light that start blinking when this happens. I looked in the troubleshooting section of the manual and it said the bulb should be replaced, so, I ordered a new bulb and replaced it. Turned the tv on and about 15-20 minutes later, it shut itself down again. I'm thinking it may be overheating and shutting itself down because of that, because after it shuts down, I can restart it and it will play for a few minutes and shut down again. Could there be a thermastat or a fan that I could check? Any help would be greatly appreciated. I live in Aiken, SC. Thanks
