    this is a common problem
    try to fix the vga pins might solve ur problem, in case it doesnt solve ur problem then,
    try to open the case of the crt monitor and see if some dust has got on to the board.Because most of the times dust make short circuits and try to clean it.then see if the plugs are tight.this may solve the problem.

    After a sudden power failure my Samtron monitor is not showing red and red related colours .What could be the reasons and how to fix it.

    I have the problem. My computer man told to effect gentle tap on the monitor and suddenly it became alright. The problem reappeared and now even a hard hit is not effective. My computer man is hard to catch hold of . He told me a part by name A... is (cannot remember what that part is) loose and that is a minor problem. Can anybody tell me the name of the part and can it be set right by me itself.

I use the 2220wm connected to my laptop. Today I noticed no red color, and after wasting the better part of an hour checking software settings, I checked the cable connection, and sure enough, that's where the problem is. I don't know it this will help solve anyone else's problem, but hey, it can't hurt to try!

My monitor's color is mixed with the color yellow

There is an option on the monitor to reset colour to factory default. Just bring up the on screen menu by pressing the left most button at the botton. Use the button next to this to highlight the colour settings which I think is the 5th or next to last option down. You will then see the option to reset colour and various other factory default settings. Happy computing

Samsung LE26R7 4BD, approx 4 years old, colour distortions

Check all of your cables on the back of the tv and your sources such as Cable,Sat box and DVD palyer to make sure they are fully inserted into the input and output connectors. Some times Component cables will work loose and you end up with a missing color. Temprature changes can affect intermittant connections. If that does work then you have a bad Main bd.

CRT monitor's background colour is changed to dull yellow colour

i think this problem accure due to chage of CRT CATHODE. if you are not a hardware engineer then check it from hardware engineer. any crt monotor have 3 RGB Cathode to release electron on screen. the electron comes shodow mask and create a pixel on the screen the pixel make a picture. The RGB color make the perfect picture. if your picture is dull then i think that happen due to less negative chage of Cathode or any Crt base Bios ic is failior. so you have to checked it from hardware engineer.

Colors not distinguishable

Is your monitor by any chance sitting next to unshielded speakers or anything else which could generate an electomagnetic field? You can get some terrific colour shifts with these items. If you do have anything like this put some distance between them and the monitor. Also the auto degauss coil circuitry could be faulty in the monitor. Take it to a repair shop and ask the tech to degauss the tube and see what difference it makes. If it fixes the problem get him to check the degauss system. Don't try this yourself. There's lots of voltage running around inside a TV. Fix don't Fry BMW
