dan's right about the reballing. I heard it is labor intensive, requiring skills and tools that aren't easily accessible. I did go to the Apple store and told them that I thought it was the display (when I really figured it was the logic board). They took the laptop from me and I paid a flat fee of $310 (+tax), the invoice said they replaced everything but the harddrive and the fans-point is, I believe you can get your mobo replaced/fixed for the flat fee.
