I have a Samsung HLR6768WX/XAA, the bulb is about 2 years old with 1265 hours on it and the color wheel is also about 2 years old. The tv comes on, it runs for about 5-8 minutes then it turns off, it then starts cycling and trying to turn on again but it's not able to, the lamp doesn't light and it keeps cycling, you have to unplug it and plug it back in, and then it will turn on again for about 5 - 8 minutes before it repeats the cycle.
all the fans are clean and running, I taped the lamp door switch just to make sure it wasn't that, I even tried running it with the back off and a fan blowing in to it, but it still turns off and if you put your hand on the lamp housing it's not even that hot, it's warm.
Is it my ballast? Or maybe a defective heat sensor? or something on the power board?
I just find it strange that after it turns itself off that it tries over and over to turn back on but the lamp never comes on.
Any help is appreciated :-)
Also when it turns off and starts trying to turn on again all three lights blink on the front
