Monitors mix the 3 "primary" colours, in various proportions, to produce all other colours.
Mix equal parts of all 3 colours, and you get WHITE.
Mix equal parts of only 2 colours, and you get YELLOW.
So, either:
1. your computer's video-card is not sending the 3rd colour;
2. your video-cable between the computer and the monitor is broken, and is not transmitting the 3rd colour;
3. your video-cable is not TIGHTLY connected at each end;
4. the electronics inside the monitor that SHOULD be producing the 3rd colour have failed.
Try connecting the monitor to a different computer, with the same video-cable. If it works correctly, your video-card is the problem.
Try connecting the monitor with a different video-cable, to see if replacing the cable fixes the problem.
Try connecting the monitor to a different computer, with a different video-cable. If it still is incorrect, then the monitor needs repair/replacement.
Eating too!! many banana's while online LOL
SOURCE: CRT monitor's background colour is changed to dull yellow colour
hello,
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.
ok
bye

may be possible that a cord from monitor to cpu is loose.
if not it is a problem in the driver ic and the cost of repair is about 20-25$
