The first thing you will notice when you remove the cover is how super
dusty everything is. Complements to the maid. You never dreamed there
was that much dust, dirt, and grime, in the entire house!
Use a soft brush (like a new paintbrush) and a vacuum cleaner to carefully
remove the built up dust. Blowing off the dust will likely not hurt the TV
unless it gets redeposited inside various controls or switches but will
be bad for your lungs - and will spread it all over the room. Don't turn
anything - many critical adjustments masquerade as screws that just beg to
be tightened. Resist the impulse for being neat and tidy until you know
exactly what you are doing. Be especially careful around the components on
the neck of the CRT - picture tube - as some of these are easily shifted
in position and control the most dreaded of adjustments - for color purity
and convergence. In particular, there will be a series of adjustable ring
magnets. It is a good idea to mark their position in any case with
some white paint, 'white out', or a Magic Marker so that if they do get
moved - or you move them deliberately, you will know where you started.
