On a set that is based on CRT technology (like yours) it is definitely
well-advised to keep the screen "full" most of the time. You also want
to avoid watching the same channel too much, or using video games that
maintain a constant background.

The problem is burn-in. Any portion of your viewing image that doesn't
change over time will tend to "burn-in" on the phosphors of your display.
The result will be a permanent image on your screen that won't go away.

BTW, the problem with watching the same channel all the time is that most
channels these days keep a "bug" in the corner of the screen to remind
you of what channel and/or network you are watching. This "bug" can also
get burned in to your screen.

This happens with all phosphor based displays.
