What your describing is a major video problem, poor color and it is blurr, It would be far cheaper to replace the monitor with a new one.

Normally monitor will receive 3 colors red, green, Blue signals from CPU. If one cable i.e Red wire connection is missing in display cable which is connected to monitor, Red color image on monitor wil be replaced with other fade color.
So, need the replace the display cable or display connector!

hope u r a u r handling chip-level repairing of monitor, knowing itz hazardous n dangerous..

however, check thoroughly for dry soulderings..(esp. at the crt base)..[this chance is maximum]..
see if the base is loose or faulty..
yes, it can b the 'chroma ic'..but don't ignore the associated components..(esp around the base)..
check video amplifier n sub section..
the colour diodes, transistors n resistances at the base..

for better supervision contact ur system admin/vendor....

No red colour in my lg lcd monitor colour setting doesnt bring any change i screeen..pls suggest some solution

it is very simple, by default in monitor circuit RGB (Red, Green, Blue) tube is installed. and in combination of both of three colors we are able to view colorful image. due to non functionalty of Red color u r not able to view red color in screen, either you replace picture tube or purchase new monitor. coz cost of this tube is equal to monitor.

Discolouring of monitor

There are several reasons for this most likely is the vga cable from the video port has undergone stress (sharp bending or crushing) this damages the cables inside and causes one or more of the colors to not display, usually red and or blue. odd it seems the green always is left unharmed when I see this...weird.
If you can I would replace the cable from the monitor to the computer. if the cable is sealed in then you may be able to find a replacement at a service center. and they could replace it for you

Green color missing from my LG 700s model

as you are electronics engineer so let us discuss technically.

as you are unable to see green colour means you might be seeing picture of magenta colour

as technically

red+blue = magenta

crt has got three cathodes

your two cathodes circuit is fine one ckt that is green cathode circuit is not working.

for that problem your will have to check

  • cable from computer to monitor
  • loose contact in crt base.
  • crt connector loose
  • voltage on green video output.
  • green video output transistor might be defective.or print loose.
  • circuit related to green video ckt
  • green video signal coming to green video ckt.
  • & finally crt defective (in rare case.)
  • hope this will help
  • good luck.

Color Problem:

in Monitor CRT Red-Blue-green cathode guns are there.. Mixing of these colour we can get the original colour chrominace technique. if any of the colour gun is faulty we would get more REad or blue or green picture. Measure RGB voltages. you can verfify which gun is faulty. if then check RGB processing circuits. Else there might be problem Chrominance colour decoder system. Contact service centre
