My monitor changes color

Charley · 21-02-2005, 06:07 PM

The monitr screen color keeps changing from normal to green, red, blue, etc.....

Wht cud be the problem?

this happens when u place magnetic items like speakers close to monitor. Now-a-days generally speakers are magnetically shieldied but maybe ur speakers are not. Due to the presence of effective magnetic field around monitor, the gaussian field of monitor disrupts thus resulting in red, blue or green patches.

To remove those patches instantly use the degauss option from ur monitor's OSD or if ur monitor does not support this feature then turn off ur monitor for about 30 mins. and dont keep ur speakers too close to ur monitor next time..

If your problem is due to external magnetic fields like suave_guy said, the abmormal colour will be in patches at certain places on the monitor screen.

If the colour changes uniformly over the whole screen, then that's a different matter. This happens when the CRT (picture tube) does not receive the proper signals on its Red, Green and Blue (R-G-B) input lines.

This can be due to various reasons. The most common ones are -

1. Your monitor signal cable is not firmly plugged into the VGA output of your video card. You can check that easily.

2. There is an intermittent break in one or more of the wires inside your monitor signal cable. This can happen if you've been using your computer for some time with the wire directly behind the VGA connector pressed hard against something like a wall.

3. There's an intermittent break in the RGB circuit inside the monitor itself, probably a dry solder. This can be checked by a competent technician.

i tried taking the spkrs off but still the same.........

but when i smack the top of the monitor the color changes normal, the colors are not only rd,grn,blue .... It turns purple, yellow, etc tooooo]

Prbly the monitr is old thts why its like that........

Then it's definitely the third possibility I mentioned. It should not be difficult for a good technician to fix.

Dump your old monitor and lets go to big apple they have very good monitors

15" - > 2500
17" -> 3500

Two contradictory statements. What's going on ?

Re Big Apple : I bought two 17" monitors from them on separate occasions a couple of years ago. The first one died within 1 year, and the second one developed a focussing problem after about 6 months. I managed to repair the first one, but couldn't do anything with the second one because the problem was with the focussing electrode inside the CRT (picture tube).

Charley · 24-02-2005, 04:44 PM

Dude, i just shfted it further away from the computer and now its working perfext but when i bring it a little closer the problem persists....

mamba · 25-02-2005, 11:03 AM

Charley · 25-02-2005, 11:44 AM

My monitor is also have same problem, its 7 year old, and left side changing color, and patches of green. now i want 2 replace it with TFT screen, by d way how much money they goona minus for my old monitor, its samtron 56V 15inch.

shyamno · 02-06-2009, 11:10 PM

I am also facing a similar prob but the difference is that along with color change my viewing space has reduced...its a 5 yr old compaq monitor....What could be the cause ? is it dead...??

toxictaz · 10-06-2009, 01:59 AM

I had the same problem too. I took my monitor to a local repairshop and the problem was solved. But I still face some problems like a constant buzzing sound and the display getting all yellowish coloured. I guess its time to dump the thing

manusag · 10-06-2009, 08:36 PM

even i had faced the same problem a year ago.My vga cable was faulty, so i replaced it.

vasishta.sushant · 10-06-2009, 08:53 PM

Loose VGA cable or exposure to magnetic field can make the monitor change colors.
But since in your case, the colors keep changing, its most probably a VGA cable fault. Check the connections.
