CRT Monitor Screen Suddenly Turned Mauve

My 5 year old Belinea 10-30-20 17 inch display flickered once and then became overlaid with pale mauve. I've degaussed it and adjusted brightness and contrast, switched it on and off and changed the resolution, but it remains the same. Any ideas?

Does a bang on the side do anything? I mean that seriously, as it worked for a while with one of mine once upon a time!

Also, check that no pins are damaged.

I wonder if one of the three electron guns has failed. You have red green and blue guns that fire electrons at the screen, if one of these fails it would cause a similar effect (I think)

Bad connection on the SVGA plug. Try a wiggle of the plug at the rear PC connection. That usually shifts the Pinky colour which occurs from time to time (i.e. every time the SVGA lead shifts) on my Medion 15" TFT monitor.

As Diodorus Siculus says, the likelihood is that one of the guns is failing. It happened to me a few years back. Same sort of colour as well.

Several sharp dunts with one of my trainers kept it going for another couple of months, but it was a dead man walking. By the way - I put a blanket over the screen while I hit the back end.

This is a good excuse for a few hours window shopping. 2nd hand CRTs are pretty cheap these days as rich folk buy TFT's, so you could find one locally.

the green gun has failed. Time for the bin and a visit to the shops I'm afraid.

There are plenty of outlets such as click here selling big screen reconditioned monitors from £35 upwards.

Alternatively, e-Buyer does new 17in monitors from around £47 plus delivery.

Thanks everybody for the humorous and practical suggestions. It's gone back to normal after a shutdown but I think it'll return in all its glory later. As they used to say in the RAF - if it isn't fixed you're not using a big enough hammer.

Guess you must have shifted the cable. Be careful of the sharp knocks on the casing. I tried that and had to open up the PC and remove and reinsert the graphics card before the PC was back to normal.

Re-seating the cable at the computer end seems to have cured it. Fingers crossed. Thanks again.
