LCD monitor's colors tremble, coloured pixels everywhere

This started about a week ago, when I started the pc, my desktop, wallpaper, taskbar were all surrounded by red green blue orange or purble pixels, that were flashing, i.e. appearing and disappearing at various places, like a winamp visualation :P. I managed to get over it by using an all-white screen saver and giving the monitor sometime off.

However, today the problem is still persisting, and even if I get over it it is only for a few minutes - then the corruption returns. I tried putting the monitor on VGA instead of DVI, changed some settings, refresh rates, reducing brightness but nothing particularly helped. Please help. Thanks.

Narrow down the problem by trying another monitor - this could be the monitor or the video card.

It is the monitor, as I tested it on my other PC.

From my searches, I found out that this may be the image persistence / burn-in problem, but I am not quite sure, as the images are not burned in, they are hust surrounded by various coloured pixels. Any additional info would be helpful.

LCDs do not suffer from burn-in, as CRTs do.  Check the cable for a loose connection or bent pin; if this is not the case, try a different resolution and see if the problem continues.

They do suffer - it is just temporary in most cases, according to what I've read.

I tried a different resolution, and a different refresh rate but it did not help.

I also tried using a VGA cable instead of a DVI but the corruption was the same.

Also, when it is not connected to a computer but is powered on, the monitor displays a "no signal" blue box with some red pixels on it!!!

This is a clear indication that the monitor is faulty and needs to be replaced.

Is this possible however? It is only a few months old.

"New" is not a guarantee that it will last the expected lifetime - mean time before failure is a statistical measure, which means some last longer and some last less.  Some brands are better than others, also.  Which brand was this one?

It is a Viewsonic $600 monitor, this is not logical.

I can understand your disbelief - $600 is a lot for a monitor, and it should work properly for a long time, but from what you tell me, it's broken.  Is there a "reset" in the controls?  If not, I don't have any other suggestions except to bring into a repair shop or replace it.

What do you mean by a reset? Also, would any shop fix it or does it have to be Viewsonic, cause I bought it online from the US and there is no such shop here.

I mean either an onscreen menu item using the monitor controls or a button of some sort that sets everything back to defaults.  Any shop that advertises itself as being capable of repairing monitors should be able to do the job.

Would changing the backlight help this situation?

No, the colored pixels are an indication the wrong pixels are lighting up, not that there isn't any light.

Was my advice that bad, as to merit a "C"?  I thought I answered your questions.

I am sorry - it was not bad, you just did not tell me a solution I did not already know.

From my research, I found out that the monitor's inverter is failing, though I cannot find a new one on the internet to replace it.

Well, sometimes the correct answer is what you suspect it is.  I don't know what other information I could have given you to solve the problem, other than the path you are taking.  See this note about grading guidlines: http://www.experts-exchange.com/help.jsp#hi73
