Preventive maintenance for a TV is pretty simple - just keep the case clean
and free of obstructions. Clean the screen with a soft cloth just dampened
with water and at most, mild detergent. DO NOT use anything so wet that
liquid may seep inside of the set around the edge of the picture tube - you
could end up with a very expensive repair bill when the liquid shorts out
the main circuit board lurking just below. If the set has a protective
flat glass faceplate, there is usually an easy way (on newer sets with this
type of protection) of removing it to get at the inner face of the CRT. Clean
both the CRT and the protective glass with a soft damp cloth and dry
thoroughly. If you have not cleaned the screen for quite a while, you will
be amazed at the amount of black grime that collects due to the static
buildup from the high voltage CRT supply.

In really dusty situations, periodically vacuuming inside the case and the use
of contact cleaner for the controls might be a good idea but realistically,
you will not do this so don't worry about it.
