Stuck, trailing pixels?

I purchased (financed) an Inspiron 9400 back in September '06 to help see me through college. Everything was good at first - no complaints - but recently I've been having some serious issues with my LCD display.

As of late, random 'stuck' pixels (aqua blue, dark blue, and red) will appear, often on dark/black backgrounds, images, and so on. When the image, etc. is moved, often a trail of similarly 'stuck' pixels will follow. Although these stuck pixels can be cleared by refreshing the page or reloading the image, it is often a matter of seconds before the pesky little dots reappear.

A couple of examples:

(Example of 'trailing pixels' leaving a pattern after I move the window around.)

(Example of a column of 'stuck' pixels appearing after I scroll down.)

I've seen a few other individuals suffering from the same issue, but have yet to find a resolution. Most of the individuals I have spoken to have declared it a hardware problem.

Personally, I'm at a loss. I still have three more years to go to pay this thing off, and I am really hoping my 3 year extended warranty will cover this.
