Monitor malfunction

[Norman McFarling]

I searched Google and did not find much, although maybe the
nomenclature was off. The image on the monitor is rock solid and
focused, but there are horizontal bars corresponding to the lines of
text. This is difficult to explain, it is like a "smear", like you
wet your finger and drug a shadow across the page by smearing the ink,
although the text is crisp and readable. More text on a line, the
darker the bar becomes.

I know this is going to date me, but my monitor is beginning to look
like that green striped printout paper we used to get reports on.
Whiz kids, say "What is Gramps rattlin' about now?"

I did notice the last few weeks that after the monitor had been on for
a long time that you could detect the "ozone" smell in the room.

Caps and cold solder??

Thanks for any suggestions.

Many times, the monitors will start to smear when the tube starts to go
weak. The best test is to have a service tech put up the proper test signals
on it, and look at the video drives with his scope to the elements of the
CRT to see if there is actually a defect in the video signals driving it.

It is often that a weak CRT can do this type of effect.

sounds like the CRT is bad, or the voltages to it are weak.

Try turning the brightness down, and see what happenes.

It also could be too much impedence in the wire, or improper grounding.

If you are an experianced tech, and know what you are doing, remove the back
and adjust the focus and screen controls on the flyback. this may/maynot
clear it up.

If your not an experianced tech, then DONT try anything with the insides.
there are lethal volteges in a monitor.
