Discharge of crt?

A couple of times at each session my new AMW 19" computer monitors display
blinks (quickly, slightly collapses and rebounds). Is this caused by a
discharge at the crt? Is this normal?

Thanks,

Dave M.

It's hard to catch. It could be either. I'm aware that the low voltage power
supply can cause both vertical and horizontal collapse and vertical collapse
is often caused by vertical amplifier gain and/or linearity problems,
but then I should be asking if you understand either symptom on monitors as
"not uncommon". Perhaps it is a momentary loss of sync caused by the video
card?

What I would do is strip it down
and go over the PCB with a Mag
glass and look for dry solder joints
very common on TV,s and Monitor
before its gets worse and wont come on.
