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

My monitor is not displaying colours.... its only showing bit of blue and yellow colour.... please give me solution.....


CRT monitors can fade over time. try resetting factory settings and degaussing, if you have that option. If not, you need a new monitor. Buy an lcd.

Yellowish screen


On a CRT, "yellow" is a mixture of all 3 "primary" colours.

So, if you are expecting some other colour, then one of the 3 "guns" that are emitting one of the primary colours is NOT working correctly.

For less than $100, you can purchase a new, 19-inch (not 17-inch) LCD (not CRT) monitor.
This is less expensive than taking the CRT to a TV/video store for trouble-shooting and repair.

Monitor


Monitor sizes are measured on the diagonal from corner to corner.

A 17" LCD may have a screen width of 12 inches measured from side to side.

If you are measuring a old style CRT monitor (Cathode Ray tube) the visible screen area will be about an inch less as there is about 1/2 inch of plastic frame holding the CRT in the chassis. The manufacturer can advertise the actual size of the screen regardless of how much is actually visible to display information.

If you are talking about software not utilizing all the available screen area to display the image, that is an issue with the people writing the software code not keeping up with the changes in hardware.

In the past year or two, most displays have switched to the 16:9 and 16:10 wide aspect ratios while most web content is still written for the 4:3 old style aspect ratio. Eventually, software developers will catch up with cusrrent hardware.

White colour is displaying as yellow


Your monitor is missing blue drive. Most likely a component failure on the CRT board. Bad color ICs, bad solder connections or defective capacitors can cause the problem.
