Cleaning mirrors and lenses on Sony big-screen projection TV

How can I clean (without calling a TV repairman) the mirrors and lenses on a Sony big-screen projection television? I had the mirror and projection lenses cleaned several years ago and it really improved the projected image quality. But, I'd like to do it myself -- that is it if the job isn't too big or risky.

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.

TV has multi color lines and a circle when I turn it on


Sony rear-projection TVs provide a large-screened entertainment solution for your home or office. Unfortunately, color problems and yellow and blue spots and saturation can occur on the face of the Sony rear-projection TV. These problems can be the effect of damaged cables, electronic interference from other devices or dirty lenses on the inside of the rear of the television set. You can troubleshoot for these problems and make satisfactory repairs without the help of a repairman. No experience with Sony rear-projection TVs is necessary.Step 1
Check the audio/video cable that connects the Sony rear-projection TV to the cable or satellite receiver. This black cable has a number of multi-colored plugs on each of its ends. Ensure that this cable is not visibly damaged in any way, and that each of the plugs is in good shape and is not bent. A damaged audio/video cable will negatively affect the quality of your rear-projection TV's display and may lead to yellow and blue saturation problems and various other display irregularities.
Step 2
Ensure that there are no other high-powered electronics in the close vicinity of your Sony TV. Speakers, computers and other similar electronic devices use a large amount of power and in turn may give off a lot of electronic interference. This interference can cause problems for your rear-projection TV's screen, such as color blurring and similar color issues. Move any such potential devices to an area that isn't as close to your Sony TV. The color blurring and yellow and blue saturation problems should then decrease over time.
Step 3
Unplug the TV if problems persist. Ensure that the Sony is completely disconnected from all power sources. This is for your safety.
Step 4
Place a towel on the floor of the area where you are going to operate on the TV. Carefully turn the TV facedown on the towel, so that the rear of the TV is facing upward.
Step 5
Remove all the screws from the back cover of the television set using a Phillips screwdriver. Remove the back cover piece by working around the edges with your fingers and gently prying the piece off.
Step 6
There will be three upright lenses in the back of the television. Cleaning these lenses can alleviate picture quality problems and color blurring. Use a soft cloth and soap and water to clean the lenses of the television. Avoid using any other cleaning solutions, as soap and water is the only universally recommended cleaner from rear-projection manufacturers like Sony.
Step 7
Ensure that the lenses are dried. Replace the back cover of the rear-projection TV and reinsert all screws using the Phillips screwdriver.

Mitsubishi wd 62527 has very dark picture changed


Clean the small front projection mirror. That mirror can get dust on it and will cause the projected image to appear dull and dim and cleaning that mirror will usually restore the brightness and crisp details in the image.

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 the bulbs and mirror on my Mitsubishi 55" WS-55313 TV.


You should re-consider having a tech do that for you. The access is by removing the screen assmbly which are somewhat fragile. If you want to give it a try, pull the speaker grill off, it comes off just from pulling it, there should be five screws across the bottom of the screen assy, remove those, there is also an access door on the front of the set with four screws, that has to be removed to unplug the cable that goes to the screen sensors. The screen assy has to be lifted straight up an inch or two and then you can pull it forward away from the set.
As far as cleaning the mirror and lenses, you can't get to the face of the tubes so it's the top of the lenses that you clean, just use a soft lint free cloth (cloth baby diaper) and wipe the dust off the lenses, you can slightly dampen the cloth with water if necessary, same type of cloth on the mirror and you can use a glass cleaner on it just don't press too hard on the mirror.

Cleaning lenses/lamps on mitsubishi VS-60805


A can of compressed air might do the trick. If dirt is stuch, I'd suggest useing the same chemicals/cloths/etc you would use for cleaning camera lenses. Check at your local photo store.

Just make sure the lenses aren't hot when you apply cold and/or flamable chemicals.
