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.
