Monitor glitch

[willmcdool]

On my 2nd 6yr old pc running w98, 2nd edition, the crt 17" monitor is a
Hitachi CM620ET. It has recently started the following glitch. Every
now and then, sometimes a quite long intervals, the screen becomes
overlain by a purple tinge. This can last only a few seconds or
sometimes a minute or two, before everything returns to normal. I've
tried everything I can think of, to no avail. Has anyone experienced
this or similar, and found a cause or fix. Or can anyone suggest a
cause or fix.

Many thanks for any help

I think it goes without waying that your monitor is dying. Time to start
shopping for a new one.

You may be loosing one of the colors (green).

When it happens again, try bending the video cable in the area
of where it plugs into the computer. If the colors return to normal,
you have an intermittant break in the video line. You can solder a
new end connector on the video cable.

If bending the cable does not work, try slapping the side of
the monitor with your open hand. If the colors return, you probably
have a bad solder connection. The picture tube socket on the CRT neck
board is probably in need of being resoldered.
Hope this helps...
