If this monitor is a LCD type then -
The problem is a back light fault and is caused by either a faulty inverter board or a faulty CCFL lamp.
You can source parts from the Internet. Try these WEB sites :-

90% chances are that this is the problem with your Graphic settings.(go to your Graphic Properties and make sure that Refresh Rate should not be more then 60Hz). Change it to 60hz and restart your machine, This should resolve.

Monitor flickers on and off

power supply is more than likely going to need some new capictors. if you can solder its not a hard fix. just look at the power supply and look for swollen caps.

Monitor on/off button flickers

The reason why the button of your monitor flickers is because the 12 volts output supply for your inverter board is not stable..
If you have the skills and the right tools for this, Here's what you need to do
1. If your monitor comes with a power supply adapter, open it..check and replace blown capacitor with same value..
2. If your monitor is using a cable power the back cover of your lcd..on the power supply section.. check and replace blown capacitor.
3. Check and resolder the terminals for fixing possible loose connections.
4. On the inverter board section...check and resolder the terminals for fixing possible loose connections, the high voltage inverter usually loose connections when overheat.
5. Other things to check if step 1 to 4 did not resolve your problem. Check and replace burnt high voltage transformer.. Check and replace busted backlight inverter..

Hope this fix your problems..

thanks.. much appreciated if you rate this help.

My pc monitor keeps flickering and jumping up and down

It could be some loose connection, check both end of the VGA cables. If this does not resolves the issue, then check if you monitor is near a high voltage cable/magnetic waves/microvave(microwave oven).
If this still dosent resolves the issue, click on the OSD menu option on the monitor, see if you find Degasus, try and use that. If not you need to repair your monitor.

All the best.

Monitor flickers with changing colors making it almost impossible to see anything, it started & stopped for a while then after maybe three weeks after it started again ! I tried disconnecting & changing...

I suggest upgrading the OS on these problem terminals to the latest on the wyse website. It might be an incompatibility with the monitor and terminal (might have been fixed in later builds), in which case you will need to log it with Wyse directly, as they will need to test this.

Chances are though you either have a faulty monitor cable, a faulty unit, or faulty monitor. Perhaps even a combination of more than one of these above problems. Try to rule out each bit of hardware before blaming anything in particular.

Try a few different monitor resolutions, colour depth and refresh rates too. Cant hurt :)

Gateway monitor flickering

I had an older mac Mini that would do that and could not use it with that monitor. it worked fine with my G5 powerpc, was probably a video card issue. I got it to work also by connecting with a VGA connection rather than a DVI
