Westinghouse LVM-37w3 developing wavy pattern

[Ryom]

My Westinghouse LVM-37w3 has developed some kind of large dark and wavy pattern across the screen. I saw at least one other poster here mention the same thing. Any other owners of this monitor seeing this on theirs? This was a hugely popular monitor here a few years back so I know we've probably got quite a few owners here.

Make a completely white graphic and a black graphic
set it to slideshow continuously in Vista or Win7 or find a way to do it in Xp
leave it on for several hours, 6 second pause between images
