I want to clean the Mirrors on my TV I know they are dirty from all the remodeling I have done in the house and the picture is not that clear, but the book says do not to remove the back panel.WHY? is there a switch or something thats will disable my TV. I was told by the TV shop something might go wrong. I am sure the Mirrors are on the top section of the back panel. I have clean mirrors before on my Pioneer 45 inch Projection tv.

Re: My Mits-Projection TV model WD-52825/WD-62825
Good Day, jmkay;
I see no reason why you can't do this yourself, but unlike the pioneer you have to approach the Mit's from the back and will have to remove the back from the screen (sort of)....charge you battery and Good Luck, big IRISH.

This may be a model that has two mirrors. Mitsubishi could tell you if this is the case.
Some idiot had the bright idea to have optical unit shine picture into tiny mirror which puts it into large mirror in back; problem is tiny mirror if there is at bottom and facing up, dust or dirt get on it and picture brightness will diminish up to 70% or more.
If model you own does have two mirrors, the front of the set with the screens will have to be removed to clean it, not real hard and takes 15 minutes.
If you can confirm it has two mirrors I can tell you step by step how to remove screen unit and resolve problem. Usually if tiny mirror dirty it will happen over time, picture will gradually get darker and dull looking.
Let me know if want instructions, the set either has two mirrors or it does not.
You will have to remove the front screen to clean the guns, but, I would want to know why you think the guns need to be cleaned. I have worked on projection sets that are 7 years old and the projection lenses are not very dirty unless you live in a very dusty area or you have done some home remodeling.
let me know if you have any more quesitons.
Here is a procedure for cleaning accessing and the mirrors:
Take the front speaker panel off and you will see two screws on the left and right top corners that hold the tabs for the screen, loosen them then go behind the tv and remove the screws around the perimeter of the back of the screen, 10 total, then remove the front center panel 4 screws and unplug the screen (easy to see which one) then just lift the screen straight up. Onced removed you can clean both mirrors. Dont use chemical cleaners, just a soft rag.
It sounds like you TV is overheating and the video is suffering and the lamp is overheating as well. Also, if your TV is over 2-3 years old, the mirrors (behind and below the big front screen) desperately need to be cleaned. Clean all filters and fans as well. (Look on side and behind the unit). Is the TV in a "hot" environment and/or dirty environment? DLP TV's are NOT sealed units. They need to be cleaned every few years to work well to have a good, clear, bright picture.
You have to be careful when replacing the projection bulb assembly. Don't aways look for the cheapest as they are rip-offs that do not last long and are not as bright. Dont buy OEM "compatible" only OEM originals. Call Mits Customer Service for advice
