Rear projection TV screen cleaning is not too hard to accomplish. This, despite the size of most rear projection TVs and the corresponding heft of many of their components, the screen included. These kinds of TVs have evolved over the years since their introduction in the 1970s, becoming increasingly more affordable and lighter and less bulky; many of the current crop of these TVs is actually light enough to be able to be hung on a wall. However, there is still a certain amount of bulk that must be dealt with if one decides to buy one of these TVs.
In this kind of TV, a projector is used to make a tiny image from a video signal from a particular source - whether from a TV signal or from a DVD or any other such source - and magnify and project this image on a screen. The projector is located within the TV box itself, and it projects the image onto the screen from behind the screen itself. This particular setup has implications regarding how the screen itself can be cleaned.
The outside of the screen is easy enough to clean. Unplug your TV first for safety reasons. You can simply use a clean dust-cloth to remove any visible particles. But if you would like a more thorough clean, you can purchase any of the cleaning options available commercially.
Firstly, there are simple microfiber cloths that can be used to clean your screen. These cloths may be gentler to your TV than the usual dustcloths, may be less prone to scratch the screen, and could also have an anti-static effect. They have other applications aside from cleaning TVs, though, so you may have to look in other places than your TV store to get one. Next, instead of this sort of cloth you can also buy sponges that would confer the same benefits. And lastly, there are also particular spray-on cleansers that are designed to be used in conjunction with cleaning cloths. These cleansers are very mild and many of them have anti-bacterial properties. You would just need to spray a little amount on the screen and wipe the dust and dirt away. (Just remember to clean your cleaning cloth itself after you're done.)
It's also possible to undertake rear projection TV screen cleaning for the inside of the screen itself. You may need another person around to help with this. First, take care to unplug the TV from the mains. Next, get a screwdriver, remove the screws that hold the screen in place, and put them in a safe place so you do not lose them. Next, unplug the wire that links the screen itself to the rest of the TV, and with help from the other person, remove the screen itself. You can then clean it with your cloth and cleaning solution. This procedure, however, might be best left to an expert or an electrician given the complexity.
