If you bought a MacBook Pro somewhere between February 2011 and December 2013, but discovered distorted video, no video, or unexpected system restarts, Apple or their authorized service providers will repair these systems for you- like an out of warranty repair- for free.
That goes for Retina MacBook Pros- their first two generations too. It is called the MacBook Pro Repair Extension Program, and will be in effect from the 20th February in US and Canada. In other countries, it will be available as of February 27, 2015, valid till three years of purchase date or February 26, 2016, whichever lands you more coverage.
These problems are specific to 15 and 17-inch MacBook Pros manufactured in 2011, and 15-inch MacBook Pros with Retina screens, built in 2012 and 2013. Users have been complaining about the graphics processing unit troubles, for the better part of three years now- well outside the warranty period.
In August 2013, Apple had started a similar repair program for iMacs with similar AMD GPUs. There was a class action lawsuit against the company, by the users in California and Florida who purchased MacBook Pros between February 2011 and May 2012. It was indicated that the problem arose due to lead-free solder in the machines, causing them to short circuit. Hardware problems, not software ones.
If a user has previously paid for repairs, Apple has arranged for reimbursements, too. Well, honesty is always appreciated and Apple knows that.
