There is a repair extension programme for video issues on the macbook pro's
However, for the OP, don't let this stop you. Call and ask, they often are generous enough to replace it for you even out of warranty. If the first time doesn't work out, try again 2-3 more times before giving up.
The AppleCare for my 2012 rMBP has expired, but is it normal for an Apple store to be so stingy about repair extension programs?
