How can I clean the mirrors on this tv?

The picture is not what it was. I was told the mirrors need cleaning. What is the correct way to do this and can I do it myself?

    really appreciate the information. Find it hard to believe that a dry cloth will clean mirrors. Is this a special cloth?

    Probably need a manual showing the inner mirrors, do you know where I can purchase this. Thanks again, Clete

To clean the mirrors you must remove the screen first there are several screws in the back to remove the screen. then there is a mirror shaped like a polligon clean this with a dry cloth do not use a paper towel. soft colth must be used on any optical surface. then clean the optical engine lens in the same manner. them the large mirror in the back. remeber if you leave a defect on any of these surfaces it will be amplified by the screen. this system relies on a lamp to provide bright picture so replace that as well. this should be a part of your anual cleaning agreement of the after market warranty you purchased assuming you bought one. dim picture = lamp, fuzzy, dim, dull picture = dust

    all you are doing with the cloth is to remove dust. a damp cloth will leave streaks the will show up in the screen. the cloth can be a lint free soft cotton cloth (this is what my company uses) or a soft shammi. if you are thinking of the DLP mirrors, that is an IC chip 1" x 1.25" sealed system made by TI. these mirrors (micro) can never be cleaned nor could they ever get dirty and is part of the light engine.

SOURCE: Can I clean projection tubes myself?

First unplug set and remove back cover then you should see the three picture tubes . Using a soft cloth spray windex on the cloth then clean your lens and use the dry side to wipe away . Do not press hard as the lens are plastic . If you cannot see the tubes thru the back side you must enter thru the front . Would need to know make and model # of your set located on the if you need more assistance . If you are a smoker this could very well improve your picture . Good luck

I have a hitachi 55vf820 lcd rear projection tv. How do you get the cover off to clean mirror?


Don't try that as the mirror almost never needs cleaning and MUST be cleaned with a special cleaner---leave a single fingerprint on that mirror (or a smudge) and it will stand out in the picture like a sore thumb.

How do I get my TV open to clean color lights I have a Hitachi 42in projection tv


You can take the back cardboard cover off to get to the lenses on the picture tubes. Usually, if the picture is dull because it needs cleaning, the mirror should be cleaned. You can remove the top half of the back of the tv and the mirror will be mounted to the inside of it.

I need to clean mirror


Most rear projection sets the screen will pop off the front. Usually a couple of hidden catches. Get another person for this.
Once off you can clean the mirror but not the inside of the screen.
Unplug tv first

Dull picture on my KP61s65


You can safely clean the mirror and lenses, it can greatly increase your picture if its dirty. If you unplug your tv you can safely remove the back and gain access to the lenses. All it takes is a philips screwdriver. After you remove the back, you can remove the light barrier between the upper and lower half to free up some room. Take a dry scratch-free cloth and wipe the dust from the lenses. If they're grimy, use a little lens cleaner (liquids used sparingly here, electronics don't like liquids, be careful) You can look up into the top and see if the mirror is dirty. A flashlight shined on it will illuminate the dust/dirt if its there. If you don't smoke you likely won't need to clean the mirror, but it may need it. Use windex or similar for tough grime.. I can usually reach up to get the whole mirror but I've heard of using a swiffer mop to reach the top. Removing the screen is difficult but possible if needed to get inside. Don't touch the back of the screen but lightly with a rag to get cobwebs, etc.

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.
