My 5 yr old ProView 19 crt has assorted minor issues, including a PS
failure I had repaired 3 years ago. Recently, the image periodically
slowly dims over a few seconds, like turning the contrast full down and
reducing the brightness. Gets medium dark, but does not disappear
completely. Then, slowly returns to normal in a similar time frame. First
time, I thought the room lights were dimming, then realized it was the
monitor. The image does not distort or shrink, and the OSD menu settings
haven't changed. The performance otherwise is excellent. It's not worth
having it fixed again; the PS issue cost $100- and it was a squeaker then.
Opinions?

Sounds like the CRT heater is losing power. Cold solder joints on the neck
board or power supply area are my best guess without looking at it. Watch
the glow in the neck in a darkened room, if it dims with the picture then
that confirms the diagnosis.

Jim is 100% correct!
