First, my disclaimer:

I have a much older projector, but the way they are constructed hasn't changed a lot to my knowledge.

An excess of dust can shorten the life of electronics, it's a given. But the majority of these sets are allowed to collect dust for many years of operation before any problem occurs.
I sense that you may instead be asking about cleaning the lenses and mirror. Actually, the mirror, since it faces somewhat at a downward angle in these sets tends to stay clean. the lenses however, face upwards, and do get quite dusty, causing a blurry picture, with ghostly images on the screen at their worst.
To clean the lenses on most RCA sets I've seen, the screen must be removed. Allow the set to cool and voltages to dissipate for 30 minutes before beginning this process. There should be a removable panel beneath the screen, usually retained by screws on the backside at each end. REmoving the panel will expose the screws that keep the screen in place at the bottom. With the screen removed, the lenses (there are three) will be quite obvious. I clean mine with typical glass cleaner and SOFT paper towels. PAY ATTENTION not to allow any liquid to drip into the projector below or you may disable the projector unit possibly causing damage that must be repaired. If you are successful at the lens cleaning you will have restored the picture quality to like new.

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

hi there,
if u know how to work with your set u can:
1. open the back cover case of your tv and try to find a foreign objects inside and clean it up with your vacuum cleaner.
2. popping sounds sometimes due to lossen parts, bad socket contacts, too much dust and dirts ,corrosions .and when cleaning you unplug first your TV set to avoid electric shock. i hope this will help a little. Thank You.

Have a JVC HD-Z886 61inch, there appears to be some black spots behind the screen. Looks like dust, most at top of screen, not a big problem. Is there any way to clean behind the screen? When new the TV...


  • The most severe problem dust can cause in an LCD TV is a short circuit. This occurs when dust enters the television's casing and settles on one or more of the internal circuit boards. Enough dust can cause a short circuit, which will prevent the TV from working at all. In other cases, it will damage picture quality or prevent certain features from working properly.

    Because a short circuit can only occur when enough dust is present inside the TV, this problem happens after the TV has been in use for a number of years, meaning that it will not be covered under the manufacturer's warranty. In many cases of short circuits, repair is expensive, and you are better off buying a new set.
  • Image Quality
  • Dust can also have an effect on an LCD TV's picture quality without entering the LCD's casing. Dust that settles on the surface can distort the picture and decrease its brightness. While it's easy to wipe the dust away, use only a soft cloth and mild cleaning solution to avoid scratching the screen or causing permanent damage with caustic cleansers.

    Dust under the screen can be more difficult to clean. Using compressed air to blow the dust out is the best option, short of disassembling the set to clean the screen from the inside. Keeping the surface of the screen free of dust is usually sufficient to prevent dust from getting under the screen.
  • Control Problems
  • Another effect dust can have on a an LCD TV occurs when it enters the space around buttons, making it difficult to control the television. On certain sets, dust will cause buttons to stick or prevent them from engaging when pressed. Using compressed air to blow the dust out, or resorting to using only the remote control, will solve this problem.

    The TV keeps shutting down due to over heating. Is there something that needs to be cleaned?


    Hi,

    Yes you need to clean the AIR FILTER located in TV.

    Please follow the steps below to clean it.

    1. Turn the television off and unplug the AC cord.
    2. Locate the dust filter on the left side panel of the TV.
    3. Using a phillips screwdriver, remove the two screws that hold the dust filter cover in place.
    4. Remove the filter cover, set it and the screws aside.
    5. Carefully remove the filter from the TV.
    6. Clean the filter material by dusting with a lint-free cloth.
    7. If the filter is soiled, you can rinse it with water. Do not use detergents or soap on the filter.
    8. Completely air dry the filter before placing it back into the TV.
    9. Replace the filter cover and secure with the screws.

    Hitachi 51UWX20B spider web like lines help


    I know my response is a while after you asked, but to clean the inside of the tv case is pretty simple.

    Remove the bottom speaker cover...on this model you just pull it off. There is no clips or screws.

    Once the speaker cover is off you will see the bottom of the screen, there is 4-5 screws on the bottom on each side....I think 4 in the gray plastic and 1 in a black metal strap. With all of those screws out pull out SLIGHTLY on the screen and push up. The top is held in with a down force clamp and you are just popping it out of that....It will pop back in once you are done.

    Now clean the back side of the screen, the mirror and CAREFULLY dust off the lenses. I myself did not want to use any cleaners (to avoid streaking) so I used a new microfiber dusting cloth. My picture became brighter and the "crack" that I thought I had was just a dust web....

    Hope this helps and good luck

    you probably have a little of both. the shutting off is definately heat related but could be too much dust on heatsinks, etc causing it to shutdown. cleaning may eliminate problem but could be a sign of an underlying issue..
    the dust can really cause the picture to dim. most of these tvs you can pull the "lightbox" or guts out of the cabinet to clean all 3 lenses, and clean the mirror if needed. don't mess with the screens except cleaning the front from outside. usually a 1/4" driver will be all you need, and a soft cloth for the lenses. use compressed air or a vacuum to clean out dust which will help with cooling, but the picture is only effected by dust on lenses, mirror, and screens.

    Need to disassemble Mitsubishi VS-6041 60 in Rear Projection


    Wow, You are asking for a complete disasemmbly. If this is necessary, you have to remove any screws you can find that are connected to the front panel. Usually they are in the top of the set ( you'll find them after removing the mirror panel and mirror ). I wouldn't remove any tubes as the tube convergence would have to be all reset and that would require a cross hair generator. I do hope this has helped in some way, but all I can do is send you my best wishes as I certainaly don't suggest disassembly if there is any other way. Good luck
