    I do not have a green color. I have loaded the drivers and still have no green showing on the monitor. It is not the monitor since I have switched monitors with no change. In Diplay, color, advanced, there is no green available to adjust.

SOURCE: no red colour in my lg lcd monitor

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.

SOURCE: Green light flickering & Sunset red screen display.

You've got components that have gone bad, probably from age and the normal heat inside a CRT monitor case.

I hate to say it, but it's really not worth fixing. You can usually find a used but working 17" monitor for under 20 bucks.

I cant see the red color on my lg LCD (flatron l1919s). instead there is like a blue light in the screen (all the pictures and faces are blue, and red events are black).


Failing internal components (but first before sending in for repair, check the computer graphics card is ok, as this, or the VGA cable to monitor may be suspect)
In effect what is happening is that the hardware that controls the spread of green and red pixels on the screen has failed (happens over time), this will need repair or more likely replacement

One of your color guns (Red, Green and Blue), have quit working correctly. It perhaps is the blue one and the red gun operating at it's usual level is washing out any other. You need all three guns to get the mix of colors, so repair is in order.

My monitor turns yellowish i can still work what is the problem. the monitor is a Acer V233H


The red "gun" of your CRT monitor is going bad. You will need to get a new monitor, and you should seriously consider an LCD flat screen. It will save you allot in electricity.

A CRT monitor is a very cool piece of technology inside... even though they are going obsolete with the advent of modern LCD displays.

In every CRT (Cathode Ray Tube) monitor, there is a trio of "Electron Guns"- they fire electrons at the front of the screen, hitting it with billions upon billions of electrons... the "bullets". Each gun is aimed at a set of colored targets, called "pixels"... one gun hits red ones, one for green, and one for blue. Combinations of these colors make up everything we can see.

When the red "gun" cannot fire enough electron "bullets" at the screen, the blue and green together make the picture appear yellowish.

If you want to learn more, look up "cathode ray tube" on wikipedia for starters!

A word of warning- the technology is very cool (I used to teach how CRT screens worked as part of my job teaching Missile fire control radar for the Navy), BUT:

THERE ARE VERY HIGH VOLTAGES INSIDE A CRT MONITOR THAT CAN KILL!!! DO NOT OPEN
THE CASE!!!!

Remember- the electron "guns" inside are shooting billions and billions of electrons at the front of the screen. They are being collected from the screen by a high voltage "supply". Most CRT's operate with anywhere from 15 to 45 THOUSAND VOLTS!

MY MONITER CHANGES COLOR AND ITS PISSING ME OFF HOW CAN I DO IT. IT ALWAYS CHANGES COLOR MOST OF THE TIME IT CHANGES TO RED COLOR


One or two of your color guns are failing. On a CRT, there are three color guns, Red, Green, Blue. They work together to produce all colors in the spectrum. If the monitor goes all one color, it generally means at least one color gun is failing. The cost to repair far exceeds the value of the monitor or the price of a new LCD panel.

The monitor has now got a blue tint I have checked the lead


Your monitor has a menu system that will allow you to access the color guns so you can adjust the red, blue, green guns that create the color picture.

The blue tint may indicate that you need to adjust teh reg and green to offset OR it may indicate that you have lost the red gun all together.

If this is an older monitor and you are considering repair... cost points say it is cheaper to buy a monitor ~$60 bucks

Color problem


There are three Cathod Ray guns responsible for the millions of colors.All colors are produced by mixing the three basic colors namely Red Green and Blue (RGB) at suitable proportion. If any one of the three guns fail firing then we get improper colors. This can be rectified by
(1) hitting the monitor at the back by keeping it on a pillow the screen facing down - it will reolve the problem if the failure is due to the loosening of the Head due to repeated thermal expansion and contaction.
(2) check the signal cable for loose connection, twisting etc on both ends - at the back of the CPU and Monitor (it is fixed)

Redless screen


If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's and CRT monitors are very hazardous to service. Even when plugged out, they can store very high, deadly voltages. How old is the picture tube? If there's lots of phosphor burn on it, chances are the red gun inside the picture tube is out. A sure-fire way requires an oscilloscope. Check the voltages on the three color guns at their corresponding pins on the CRT's neck board. You can see their levels change as you tweak their adjustment pots on the neck board. If the red voltage is present and at the same levels as green and blue, then the gun inside the tube is shot. If the red voltage is NOT there, then you can work backwards and find out where you're losing it. It could be a bad buffer amplifier (transistor or I.C.), bad solder joint, or even a broken wire in the cable harness. check for cracked solder joints where the RGB, Grd Sync connector is. check the pins on the molex power supply connector, could be that the pin for the red is pushed back and is not making contact. Try swapping the red and green inputs if you see red on your monitor and no green, then it is NOT the tube. If you see no red still but still get a green where red should be I would suspect a bad chassis.
