Question about Mitsubishi Televison & Video
Well this is gonna take some work... First thing to start with is...
When you replace the bulb/s -does the bulb actually illuminate?
If you shine a very bright light into the surface of the screen can you see a faint image of whats on the set?
Do you get sound?
If the bulb is illuminating, is it blowing soon after?
Did the set return to normal operation after replacing the bulb the first time?
Side Note-Never touch a high power bulb glass enclosure because you can leave oils and moister that lesson the life of the bulb or make it more prone to blowing. I have no facts to support this note beside my own experiences but this is a known "thing".
Questions? Just ask. Mr.Mike

I am not sure about your model but a call to Mitsubishi to ask if the set has one or two mirrors would offer a possible explanation---the ones with two mirrors have a small one at the bottom--it gets coated with dust and brightness drops up to 75 percent----other possible reason is the lamp may be nearing the end of its life.
I would have Mitsubishi look to see if this model uses the two mirrors--if that is the case cleaning will cure this--if you find it has two mirrors I can tell you what is involved--on Vacation but do look here--let me know what you find.
