SOURCE: Dark screen since new
Wow only 10 then major work, hum. First if pic is:Split screen picture with one half darker than the other half. "Deep Field Imager" is set to the demo mode, press the "video" button repeatedly to cycle through the video settings until Deep Field Imager is accessed and then change the setting from demo to "on" or "off" depending on preference. Also u can try:1. Dark blue raster with faint movement in the background, suspect the FMT PCB part # 934C153001 . Also1. May be intermittent. Remove and reseat the DVI cable between the Chassis and Optical engine 2. Removing and reseating the DVI cable does not resolve, replace the Optical Engine part # 938P015020 Hope this helps Tom!!

I've seen this in two scenarios.
First: The housing of the bulb is dirty (the lens the bulb lights onto) and the internal screen is dirty also.
The second: The bulb is wired reversely of the proper way to wire it. This will light the bulb, but will not light as bright as when it is wired correctly!
Thank you and please rate!

Most likely you have a bad INVERTER module, this module supplies high voltage to the baklight assemble which is likely why you can only see a very dim display on your LCD TV. The inverters are relatively cheap. Hope this helps ! Good luck..

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.
