Red color missing in LCD monitor


if under warranty contact the manufacturer for repairs. otherwise you'd be in the market for a new monitor.

Also check your graphics card. Might be causing the problem rather than your monitor.

No red colour in my lg lcd monitor ..red 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.

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.
