SOURCE: brightness sometime too light and sometime too dark

I would say there is a problem in the horizontal / high voltage section, but I have no information on this model.

It's time to RESPONSIBLY RECYCLE any 17-inch CRT monitor, and buy a LCD monitor;
used LCD monitors can be purchased for under $50.

It would cost you over $50 to take the CRT to a TV/Video repair shop, for trouble-shooting and repair.

bcollier696, You did not state how many hours of use this small screen monitor has on it!! You may need to replace the CRT if it has been in use for a long time. Can you approximate the total "ON" time of said unit? Is it >10k hrs. Multiply hrs/day x 300 days x yrs of use. If u come up with 15k hrs or more replace the unit with an LCD if possible.
