My wife's 17 inch monitor works fine if its used daily. If its been off for
a week or so, it takes about 1/2 hour to gradually come from a black screen
to full brightness.

I assume this a a sign of a bad capacitor. Since the problem resolves
fairly quickly I expect I will have a problem finding the real culprit
without changing out a whole lot unnecessarily..

Should I suspect something in the power supply or one of the caps in the CRT
filiment circuit?

Thanks for any tips.

I would start with an ESR meter to test the caps in the power supply, and
then go over to the scan sections.

That's the first place I'd look...could be a bad capacitor, or even a
bad connection.

Thanks for any tips.

For gods sake wear rubber shoes

Or better still take it to a service centre
