Monitor colour is ok in the middle circle and on right side it seems to loose the red colour and on the left it seems the green colour is missing.


The CRT has likely become magnetized. On the monitor's main menu there is a "degauss" option. It is the option depicting a horseshoe magnet. Select that option to degauss the CRT, and the color distortion should clear up. If it improves but does not clear up entirely, degauss the CRT again. Is the monitor situated near a magnet (such as a speaker, a subwoofer, or some other source of magnetic field)? If so, either move the monitor away from the magnetic field source or move the magnetic field source away from the monitor, then degauss the CRT by selecting that option from the main menu on the monitor. Was the monitor dropped? If so, a series of electromagnets at the back of the CRT (called the "blue lateral") may have come loose. This is somewhat challenging to align and is best handled by a technician.

CRT monitors can fade over time. try resetting factory settings and degaussing, if you have that option. If not, you need a new monitor. Buy an lcd.

Hey. the problem with my monitor is that .....at the top right and left corners of my monitor d colour has been changed to red ..ie even if open a new window is opened is maximized its size the same...


The most probable cause for this is some magnetic field present near these areas, which cause the monitor's mask getting magnetized. I would guess that you have speakers on the monitor's sides, right? You need magnetically shielded (good quality "computer" type) speakers, or else move the existing ones away from the monitor.
The DEGAUSS option from your monitor's controls is used to de-magnetize the mask. You are sure to find it in the monitor menu. Or if you can't find it, simply switch the monitor on and off a couple of times (off, 10 seconds wait, on, 30 seconds wait, and so on) - degaussing is (should be) performed upon every power up cycle.

My brother placed a magnet on my moniter screen since then the screen shows different colours?


Have you displaced the magnet now? if not do it. Even after displacing the magnet retains the problem, you need to again keep the magnet as it was placed last time, this will discharge the electromagnetic process. Good luck

Samsung 794mg --- problem in monitor screen --- uneven colour mix


sounds like the monitor experienced being close to a magnetic field.

if the monitor doesn't have a auto degaussing (demagnatise) function on start up, then try using the degaussing function on the monitor (in the menu somewhere).

if no good, then you can try moving/waving a magnet near the affected area. b careful! slowly wave the magnet from a distance 1st, until you have improvements. too close and it will change the colours further!

Colour


The CRT shadow-mask may no longer be degaussing, or the shadow-mask in the CRT is defective.

In or near to the power supply there is a thermoresistor that controls the degausser coils. When the set is turned on this thermoresistor gives a momentary high AC current to the degausser coil with a rapid decay for slightly over a period of about 200 ms or 1/5th of a second.

If this thermoresitor is defective, it will have to be changed to resore the degausser coil to work again.

On rare occasions I have had a bad degausser coil that had to be changed. I have also had the shadow-mask in the CRT become defective. The fix for a bad shadow-mask is to change the CRT. This is not feasible for this TV set!

You should get an experienced TV service tech to fix this for you.
