To insure the best picture quality for your unit you should clean the mirrors and lenses on picture tubes every 3-4 years if you smoke in the house this be done once a year because of the nicotine build up you can do this yourself by popping the screen off the front very carefully or call a shop they should do it for about a hundred dollars but well worth tv will look a hundred times better

clean lens on Mitsubishi VS 8087?


hello!really, you can't clean lens to improve the picture quality. it just won't make it worth. I've seen lenses and mirror covered with 1/16 inch layer of the dust, smoke, etc. Wiping them off didn't make much difference if your CRTs(picture tubes) are strong. If those are weak or coolant contaminated(cloudy), no cleaning will drastically improve the picture. Except for "basic" cleaning, which requires disassembling of the cabinet, detaching the mirror and spending couple hours to do so, there is not much you can do yourself. Replacing coolant requires 'top gun" skills, restoring CRTs emissions requires $1,000+ device and knowledge "how to" and 'how not to fry" tubes. If picture is not too bad, but out of convergence, there is nothing to do with any procedures, described above. Especially, if coolant leaked onto boards(very common problem). In any case, there is a MAJOR repair involved, possibly at the board replacement level. Not a D.I.Y. project.If nothing relates to your case, just poke set open from the back(carefully) on top of the "bulge". Clean it with "windex" or "invisible glass", using "bounty" paper towels and try to enjoy the show!good luck,Alex.

I am replacing the bulb in my three year old DLP television. The replacement is straight forward. I wanted to know if there is any preventative maintenance I should do to the mirrors, lenses, or cleaning in general. The television is a Mitsubishi model C-80.


No. Just keep you house clean and vacuum often . Keeping dust and dirt to a minimum is the best way of keeping the fans in the tv from drawing that dust and dirt into the tv. Also cigarette smoke will destroy this type of tv. If you ever get a dark spot in the picture it may be dust on the lense. You can dust the lense with only a microfiber rag.

cleaning lenses and mirrors on dlp


I have found a way to clean these, the mirror is very sensitive and doesn't have a glass coating like a regular mirror and if you touch it with your hand (or in my case my forehead) even the tiniest speck of oil will distort the picture but without touching the mirror you can use a new swifter duster, any sort of cloth or tissue will leave lint. So I dusted the mirror first in case any dust fell then I cleaned the lens and blew them both off gently with air and it works great.
