I change the bulb in my Mitsubishi 73inch dlp tv. And now it turns on for 30 seconds then it it starts glitching then it turns off. Is this something that can be repaired? Please let me know, thank you

Most likely you need to replace the projection bulb. You can find them online. DLP sets are famous - or infamous - for burning out the bulbs/lamps.

Hello, all i can say is it may have been a bad lamp, see if they'll warranty it....tks

Probably needs a new projection lamp. Have you read the user manual?

try the following website:

Try cleaning the little fans that keep the bulb cool, the temp sensor will shut it off so not to damage the bulb , the winning sound may be the fan going bad or not working like it should.

If you tried a cheap bulb then that might be the problem as some of the bulb carrage may not be complete4lyto spec. I had one that was close but there was a gap between bulb and where it fits. I went with a bulb dealer that had I believe a 1 year warrante and I have had no problems. I had a 73838 tv set.

You need to replace the DLP chip. Get a quote form a TV repair shop.

Honestly I would try entering the 'Lamp timer reset' code again. Or the button sequence given to reset the lamp timer.
An issue that may be happening is that something may have happened to the lamp ballast power supply also.
Just a thought.

If the second light is blinking to orange or red, that is usually the lamp indicator light on an LG DLP tv. That indicates your bulb needs replaced, or something surrounding the bulb has failed (like the cooling fan for the bulb for example) IF you have a spare bulb handy, I'd replace the bulb, keeping in mind if you touch any part of a new bulb with your bare hands, you just cut the life of the bulb by more then half.

you have the same problem I have. The problem is fixed by changing the new light bulb. The problem appears again after 1500 hours of use. You can keep buying new light bulbs or avoid it by not buying another Samsung TV.
