most likely, there isn't a thing wrong with the monitor. given the "checkerboard" pattern, i'd suspect the vram on the video card, try pulling it, cleaning the contacts (with a clean pencil eraser, then blow off the crumbs) and try again. you might also pull the vid card and clean it's fingers the same way. it could possibly be the connector on the video card, they do tend to take a lot of strain and can crack connections but i doubt it. if at all possible, try the monitor on another machine or with a different card, and ideally a different cable. you said you know the cable's not the problem, but how? if you wish, contact me off list or repost the details of the model of mac, vid card, and monitor, i know a lot about monitors and may be able to help. in any case, try the above first, and i really, really doubt the monitor has a problem, it's unusual to lose all 3 colors, there's no monitor problem that would produce the checkerboard pattern (imho...), and you have a raster (i.e. the faint rectangle and scan lines where they should be) so the deflection is working (and the deflection circuitry is one of the things that tends to fail on monitors). obviously, also check the brightness and contrast again, i've missed the obvious before myself. also, i assume this monitor was known to be working before? how about the video card and mac? trying the vid card and mac with another monitor if possible would also be illuminating. finally, as a few people have mentioned, some monitors and vid cards are wired oddly in a nonstandard way, which rarely causes damage (most video cards/monitors are pretty robust as far as wrong signals go) though obviously it can prevent proper operation. it is odd that the symptom changed, but if it was a vram problem it makes some sense.
