Hello everyone,

A couple weeks ago my monitor screen became pink for a second or two.
Since than it has become during the day pink for maybe 6 minutes.
That happened a couple times but not everyday.

I fooled with the Monitor cable and nothng has happened I thought it
might be the videocard.
I brought the card into the dealer who checked it for me and said the
videocard is OK, but the whole PC might have to be checked it may be the
motherboard.

Is that possible?
Has anyone else had any similar experiences?

I'm thankful for all tips.

From my experience this normally indicates that the monitor is on the

All the monitors that were defect by me only showed a blacksreen
(nothing at all)

Have you had any different experiences?

Someone suggested using a different VGA cable between the monitor and PC.

I have not tried that yet.

If it's a flat screen LCD monitor it could be that the cold-cathode tube
that lights it up is dying. A pink colour can be indicitive of a dying tube.

Otherwise it could be sun spots maybe?

No, it is not an LCD monitor.
It's a CRT.

If you are driving from a graphics card I doubt it could be the
motherboard. The colours are derived from memory on the graphics card
and its circuitry, not from other parts of the PC. For the rest of the
PC to change colours it would have to write different bytes to the
graphics card's memory.

I have seen similar when the connection at either end of the monitor
lead was half disconnected. One or two colours were switched off. I
take it you checked both ends of the cable were secure.

Sounds like cable, monitor or graphics card.

I have. Of the times where I've had a color tint problem, as radical as
you describe, on a CRT monitor, it has been a problem with the monitor
itself. It might be something as simple as a discontinuity in part of
the cable, but for a CRT monitor, that's typically hard-wired to the
unit. Sometimes you see this when someone has been pushing the monitor
back against the wall, causing the cable to bend at a sharp angle.

If your monitor is such that it has connects on both ends, then by all
means try a new cable.

I also can't imagine it has anything to do with the motherboard.
The graphic card was already checked.
I must have something to do with the other two.

It sounds like the red electron gun in the CRT tube is slightly
increasing its current flow. It could be caused by a poor solder
joint in the drive circuit.

That sounds technical to me, but if it has to do anything with the tube
it's probably beyond economic repair.

I only experience it ONE TIME in my life where the color had to do with
the montor.

In 1996 I got a Siemens (17 inch) monitor back from repair.
I received a used monitor and it ALWAYS showed a yellowish tint.
It had an expensive RGB cable and after replacing the cable it still did
not help.

If you disconnect the monitor from the PC, is it still pink? Look at the
onscreen menus of the monitor (or the "monitor is unplugged/in powersaving
mode) for something to look at.

The fault is intermittent, though, isn't it? If so it may also be in
the graphics card and not have shown up when tested.

No it is not.

Yesterday the screen became pink again. I changed the VGA cable and it
stayed pink. I changed the monitor and it seems to be OK. I HOPE it was
because of the monitor. I have to wait and see what happens.

Maybe it is coming out of the closet? It has been afraid of its sexuality
for years, and finally decided that now is the time to announce it.

If it is, I would like to use that freed up closet space for a CRT here.
I can't bring myself to throw it away, so I just keep tripping over it.

It sure sounds like the monitor. Since the problem is
intermittent, it's not likely to be due to an aging tube. It's
probably an intermittent fault in the electronics driving the
green or the red cathode.

I could not believe it. IT WAS THE MONITOR !!!
I never had that happen to me before. In the past when the monitor was
defect all I had was a black screen.

Thanks to eveyone for their support.

Actually it was quite obvious to someone with experience in
electronics, especially once the video card and the cable had
been ruled out.

As with any other complex technical product, there are many
separate functions that can go wrong and the symptoms help
isolate the culprit. Then, if the product is worth repairing,
pinpointing the defective part is a combination of tests and
mental process of elimination. Repairing your monitor wouldn't be
difficult for a competent technician in a less advanced country
where labour is not prohibitively expensive.
