Here is an image of the MBP screen, posted bny Dave's Son!

Its the Apple store genius bar for this MBP.  They will be able to determine exactly what the problem is and tell you the associated costs for repair.  I hope it falls within the parameters of the support article that wjosten posted.

Good luck.
