Question about Mitsubishi WD-60638 DLP TV
I have replaced the lamp because it blewout and not it will not stay on. When I turn it on it stays on for 30 seconds and then you can hear the fans turning off then the TV shuts down.

Hi Sally Jo, Unit powers on and works properly for a while then shuts off with a red lamp LED (lamp error). Suspect bad lamp part # 915P020010 2. Lamp enable line at J14 pin 6 does not switch to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010 3. At power on the lamp turns on and off three times and then the unit shuts down with a red lamp LED (lamp error). Replace the Light Engine part # 939P977010 4. Check for 12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check for an open F9A09 on the Power PCB, if it is open replace F9A09 part # 283P127060 and the Light Engine part # 939P977010 5. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on but does not go back to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010 6. Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if missing replace the Power PCB part # 934C148001. Hope this helps!

Mitsubishi has problems with the thermal sensor going bad. They extended the warranty for several sets. The sensor is right by the lamp. Call mitsubishi and insist they do something for you. If you keep playing your set, the bulb could also be at risk. I would think your set is covered being a 62" set. Good-luck and be sure to act ASAP.

Don't know if this applys to you but if you have purchased anything but Osram or Philips replacement lamp for your DLP tv then this is probably your problem.. The generic is VERY tempting in this recession but in this case generic is poison to your dlp tv... i have a Mitsubishi 60735 and went thru 2 generic bulbs when my tv kept shutting down on it's own and the lights on front would flash, i could cut it back on for 10 minutes then flicker and shut down again ..well since the bulb was new i thought it may be defective so i got is exchanged for another one ... after all of the post i have seen how much repairs were going to cost on dlp sets no matter what the problem was ..i was ready to chunk the tv out the door when the second lamp was doing the same thing.....!! well a last ditch effort to save my tv before i trashed it or taking it apart to dissect it.. was to buy a brandname lamp ... in my case i purchased a Philips ..it cost twice as much =/ ..i could just return it if it didn't work.. well it was the generic lamps that was causing trouble.. the brandname worked perfectly .. i am just glad the generic lamp didn't do any damage to my TV!!! I have done further research on the generic lamps and realized that the damage it could have done was not worth the money i saved when i purchesed it... Generic is a great deal In some cases (household cleaners, etc..) but in this case GET THE NAME BRAND!!!! the only name brands i know of for these lamps are Philips or Osram/Sylvania.. hope this helps others from this headache. Do your research don't by generic lamp replacements, your DLP set cost to much to risk it.
