[CUBE] Interesting cube video behavior

[butlwl1 at wfu.edu]

I don't think it's the Degauss problem, though it does have a 
Degauss function. It doesn't make any noise when this problem 
normally occurs. And the screen itself doesn't shrink...the middle 
portion just loses a bit of focus/looks more wavy. It seems to 
resolve itself without effect. Hope someone can help...

If it's one of those crt's that does degausse when you turn it 
on it 
might be the circuitry that controls that going bad, when the 
screen 
dims or shrinks does the monitor make a noise?
