A few things occur to me, if Lamp not recently replaced (2year average life) it may be nearing the end of its life.
Just a few models (not sure if this is one) use two mirrors where most just have one large mirror.
If the issue was gradual you may have the two mirror set, one tiny mirror at bottom of screen area points up and reflects the image into the large mirror in the back of the set which puts it on the screen to view.
If your model has the two mirrors the little one will be coated with dust and such and cuts brightness up to 70%
You can call Mitsubishi and ask if your model has two mirrors or one, if Two mirrors and they will not tell you how to get at them I can.
Let me know if you need more help.

I just bought an e 62525 on craigslist for $300 dollars. The guy had it in his garage because of a degraded picture... white out haze and virtually no black ... I surfed for similar issues most referring to the light engine. However; going back to basics. I removed the front panel assembly (approximately 16 screws including the center panel surrounding the card/rca ports in the front). The main mirror was spotless (in itself missleading) but the projection lense and the smaller mirror were frosted over with 3+ years of fine dust. I cleaned them with a simple cloth. I also noted that the foam insert surrounding the lense had gaps due to age which allowed excessive light sepage (the white out problem). I repositioned the foam as best I could. Then simply stuffed a black cloth over the foam but firmly arround the lense (keeping the foam intact as well). This blocked "all" light sepage. Bottom line is that I now have a picture quality that is flat out incredible! This is one bad mutha (shut yo mouth) tv. P.S. I'm just an average guy with an electric screw driver.

If the tv looks now dark this is the first symptom of a lamp replacement (refer to the user's manual to do this job) and get a Mitsubishi original replacement.
the best picture setting (when the lamp is back of course) depends in the light of the room.
Now if after replacing de lamp and playing with the settings and the screen still pale, dimm, not enought color. a cleanning in the reflexion area is needed. (technican job)

If the lamp light turns red and the set wont power up put the V26 Power repair kit in and that should take care of it. The kit contains the capacitors and detailed instructions on CD
