The screen turns green after playing videos for 20 minures


The Video Controller works off of the RGB principal. RED/Green/Blue pixels. The mix color is dependent on the formation and density of the pixel and rates. When one or more colors are absent the only functioning color will dominate, and it is Green in your case. The screen liquid crystals in Red and Blue are failing and only a screen replacement will fix the situation.

My tv screen when on turns yellow then after a while it will switch back to normal colors what can be wrong with it....


Televisions covered: all Projection with yellow picture, but not Projection TVs with a yellowish tint surrounding objects in a nearly normal picture.

Yellow = red + green
normal picture = red + blue + green (RGB). See illustration.

Fig. 1 Additive color mixing in an RGB monitor, or RGB Projection TV.

The circuitry powering your blue output, or the blue light engine itself is starting to fail.

Operating Theory:

The lamp module shines a bright light into the optical unit; there are a series of lens and baffles, and at the top of the light engine, a lens puts the picture into a mirror which is reflected onto the screen; All video and color is processed thru the light engine. Blue most commonly fails first, leaving a yellow picture.

Monitor only displays blue color, no red or green


hi there, it may be that the RGB balance has been changed. Try getting a person that knows about monitors to calibrate the colors correctly. Or, connect the computer to a different monitor. If it still displays blue, it's a problem for a expert.

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.

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)

Colors reversed on samsung 2220vm


You got a loose connection on your VGA 15pin Socket. everytime the color signal got loose there is a invert video.or missing color signal.Possible cause in which terminals in a bad contacts with wires. preparably the RGB color signal, replace only the 15 pin male socket... which is pin 1 for Red pin 2 for Green pin 3 for Blue..
others pins just trace the signal.. don't worry its color coded.
