I just had a similar thing happen on my Ti550. In my case, it was only the lower third of the screen that was affected. It got progressively worse. In the course of a week it went from being annoying to unusable. I still had it under Applecare so I made an appointment w/ the Geniuses at the Apple store. The one at the counter took one look at it and said it was the logic board. So they shipped it to Apple (or where ever it is they farm to work out to). Once there, the techs determined it was the display and replaced it. When I went to pick it up, they had my aftermarket 512MB chip in a bag w/ a note from Apple saying the cause of my problem was the aftermarket chip. I left it alone for a day, put the chip back in and proceeded to stress test it for another two days (nothing special, I was just editing video in iMovie). No more problems, everything seemed OK. Between you and me, I think it was the screen.
