Same scrambled video on external monitor = bad news. Probably a faulty graphic processor unit and that means a logic board replacement. Try all usual troubleshooting procedures (pram reset, PMU reset, etc). If nothing restore the video then replace the logic board.
Here's a link to troubleshooting steps:

I'm not looking forward to opening up the monitor but your common-sense response is very helpful. Thank you!

I have a scrambled video problem on mine too, but it only happens when the tilt of the screen isn't exactly right. Couldn't this be a short-circuiting cable?

Yes it could be a bad LVDS (video) cable or a faulty LCD screen. First connect your computer to an external monitor and if the video is normal on the external then try to reseat LVDS cable both ends. If it doesn't solve the problem, replace the LVDS cable. If you still have the issue then the LCD panel need to be replaced.
