Vertical fading lines across entire lcd screen.

I was swapping out the Hard Drive in the iMac. I only released two cables from the LCD (the V-Sync Ribbon and the Data Cable) just so I could tilt the screen out enough to get at the HDD. Everything went fine up until I was installing the new HDD when at some point i got a pretty nasty shock through both arms. I don't know exactly what i touched but I was holding the LCD at a tilted angle in the frame at the time and dropped it about 4 inches down onto the computer.

I plugged everything back in and booted it up. Now the screen shows vertical lines across the entire screen. each line is a solid color, top to bottom. The color of the line resembles an average of all the separate colors that line should be. So when I have the default purple galaxy wallpaper and a finder window open, the screen displays purple bars on the sides and a big white bar in the middle. The strangest thing is when something changes or moves. The display slowly fades to the new colors. For example if I move that finder window to the side of the screen, the white bar in the middle slowly fades out and a white bar on the side slowly fades in. like 10 second fade time.

Everything else seems to be running properly. I'm controlling the computer with Screen Sharing from my laptop. I also pulled the iMac back open to double check my cables and everything appears to be connected properly as far as i can tell.

I'm thinking that Zap that went through my arms also went through the LCD that I was holding and toasted its insides. but I figure I should ask before going out to buy a new LCD.

And yes, I know, I should have unplugged the thing before opening it up. but I didn't have a static discharge bracelet handy and was using the iMac's frame to discharge through the plug.
