After almost two years of ownership, my Macbook Pro is acting up. In the middle of using it, the screen image will turn into a negative image of what is on the screen without me doing anything, pushing buttons, etc.

I can temporarily fix the problem by tilting the screen back or forth a little bit, and the screen returns to normal. This is now happening several times a day. Any idea what is causing it? A loose cable connection to the monitor? A video card issue?

MacPro, Mac OS X (10.6.2)
