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.

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.

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.

Red Green and Blue (RGB) at suitable proportion. If any one of the
three guns fail firing then we get improper colors.
Try
(1) Simply tap on the monitor and see the result.(Keep the monitor on during this trial.)
(2) Disconnect the Monitor.and Slap it at the back by keeping it on a pillow with the screen facing down - it will resolve the problem if the failure is due to the loosening of the Head due to repeated thermal expansion and contraction.
(3) check the signal cable for loose connection, twisting etc on both ends - at the back of the CPU and Monitor (it is fixed) -
(4)tighten the screws at the backside of the CPU

Best of luck

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
