Black pixels replaced with pulsating red

My display has been broken for half a week now but it functions well enough that I could use my computer. It's really irritating though.,

Symptom: Black pixels are replaced with a pulsating red. Not all black pixels are replaced, but whenever I'm loading using anything, the whole dispaly shows red lines, kind of like red and black static where the black should be. Only certain areas of black are replaced, and I have reason to believe that it is when the pixel has no assigned color that it is replaced red. It is inconsistent. There are times when I reboot it that it doesnt do this, but then it comes back in the end. I've run a pixel test on the the computer, and the "black" test fills the screen with red.
Please help!!

Macbook Pro, Mac OS X (10.6.4)

System Preferences>Display>Display
Check the Colors & Brightness settings.
My Color setting is set to Millions which I believe is the default setting.

Now click on the Color button.
Check Display Profile
Is Show profiles for this display only enabled or disabled?
If necessary click on the Calibrate button & do the necessary.

Now in the bottom right corner, click on the purple button w/the black ? mark in the middle. This will bring up the help window.

Midway down, click on the Colorsync Utility link.

The next window should be Profile First Aid.
Read & follow the instructions/details of About Profile First Aid: & do the necessary to Verify & Repair.

If the above does not work, take the MBP to your local Apple Store or AASP. Hopefully, you have AppleCare or ProCare.
