Hello, I have a Samsung DLP HLR5667 and it blew a lamp 4 months ago, I replaced the lamp and it worked fine for about 2 months and started shutting off after only running for about 90 seconds. I reset the lamp hours and it worked fine for another 2 months. Now it is shutting off after 90 seconds of running, first the picture then the audio. All three lights then begin to blink. Troubleshooting I have performed is 1. I have cleaned the interior of the television. 2. Jumpered the lamp door switch. 3. Jumpered the thermostat. 4. Reset the lamp hours. Can anyone help?

Thank youb for your advice, I do feel comfortable enough to tackle myself, however, I am not getting any audible signal that the color wheel is bad. What leads you to believe that it is the color wheel?

Because your lamp is good and your ballast is good and all 3 leds are blinking. This is the common problem with that chassi these days. Your wheel is good enough to get the set started, but cannot keep a good RPM so the set is shutting down. You might be able to notice on you picture if it is bad enough. Before it shuts down look close at the display. You might be able to see the colors shifting a little bit. Because your lamp is good and your ballast is good and all 3 leds are blinking.
