Television and Home Theater

5 years old - about 3-4000 hours. Runs ten minutes then shuts off and comes right back on after the power LED blinks like it does when it ordinarily comes on. Over and over. I've blown everything out with a compressor and the cooliing fan behind the lamp is running.

Thanks,  Mike

I just replaced lamp on 2007 dated unit [set has been run almost 15 hours a day as we do not turn it off even if we go out].  Used Philips replacement lamp module of course.  Picture is great.  TIP: new lamp module would not guide to plug into ballast electrical connections, but removing the ballast module and mating the two was simple and fool proof; you only have to loosen the supply and fan wires from their clips to get the ballast module all the way out.

After lots of diagnostics, web browsing and phone calls I believe I have narrowed down my issue to the DMD temp sensor malfunctioning. This all started about 3 or so weeks ago. I had used my TV a bit earlier in the day and use it as my pc monitor as well. So I turned it off and came back 3-4 hours later, powered on, then after 1-2 minutes it powered off on it's own and then has the solid yellow LED and gives me a code 39. So i checked the lamp, the ballast, and the lamp temp sensor and they all appear fine.
