I just cleaned my 4 year old panasonic PT47WXC43G's mirror and bulbs using alcohol free baby wipes and a microfiber cloth to dry them off. I did this because my tv started to look like crap. The picture was extremely foggy. I had incredible success doing this! Saved me about 2 grand. Now I don't have to buy a new TV now! My picture looks just like it did the day I bought the TV....If not better!

You can get to it by removing the back panel. You also have to kind of lay down beside it and kind of twist around with your head to see what your doing. But it can be done. It helps if you take the two screw out that keeps the shelf that's around the picture tube assemblies it gives you a little more room. Don't use windex though it will streak it up bad. Just a damp soft cloth and then dry it good. Makes a big difference in picture quality.

SOURCE: Location of MIrrors in projection tv

wd-52525 This is a DLP, I dont suggest taking it apart to clean anything, this is what we call a MICRO display, the imaging device is about 1" square and blown up 50X to the size of the pix you watch, anytime anyone I know has taken stuff appart where the mirror is at has ended up worse off, you say that there is dust on the mirror, what does it look like in your picture? If the spots are quarter size or so and fuzzy edges the dust is inside the lightengine and you want a factory cleanroom to service the LE, the one thing I think you can safely do is pull the lamp and check for dust on it as it can cause issues in pix, other than that I dunno what to tell you, hope this info helps.

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.

Tv color not bright enough and just replaced lamp

Clean the small mirror in front that projects the image onto the rear mirror. The Rear mirror always stays good but the front small mirror gets dusty and the colors and bright levels get affected and appear dim.

Cleaning mirror and how to get in there

Hello timbick45,

You want to remove the top rear panel. Remove the screws and the top, along the sides, and along the middle of your TV (from the rear). Onec that is done be very careful because the mirroe is attached to the rear panel of the TV. set the back down and with a clean cloth and a can of air remove the dust off of the mirror, use a light window cleaner, after removing the dust. To clean the bulbs just use air to blow the dust off (not not attempt to clean the bulbs with any solvent.

I hope this helps

Thank you,

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

Cleaning rear projection screen tv

It is very rare to have to clean the mirror. It us upside down so it does not collect dust. It does however collect nicotine if there is a smoker in the house. Some RCA mirrors are not glass and should not be touched. The lenses do get dusty and should be cleaned.

Cleaning mirrors and lenses on Sony big-screen projection TV

it's fairly easy to remove the screws on the back bottom portion of any rear-projector television. when the bottom part is removed, you will see both the mirror and the 3 lens. isopropyl alcohol or windex should do an efficient job. a soft lens rag can be found at any camera store. i'd spray the lens rag instead of the actual lens or mirror when doing this job.

Dark color

Have you tried polishing the projection mirror and changing the coolant in the CRTs. The mirror alone can make the picture dull. Do not use windex to clean the mirror, just a soft damp cloth then dry. You can access the mirror hrough the back panel its a bit of a reach but its do able from the rear the mirror is directly above the rear acess panel.
