In a statement passed along by the guys at 9to5Mac, Apple explains that it has identified a fault with a small amount of AMD Radeon HD 6970M video cards the company used in the production of its 27-inch iMac computers, between May 2011 and October 2012.
“Apple has determined that some AMD Radeon HD 6970M video cards used in 27-inch iMac computers with 3.1GHz quad-core Intel Core i5 or 3.4GHz quad-core Intel Core i7 processors may fail, causing the computer’s display to appear distorted, white or blue with vertical lines, or to turn black.”
“iMac computers with affected video cards were sold between May 2011 and October 2012.”
According to the site, Apple has now also launched a ‘GPU replacement program,’ which will reportedly see the Cupertino CA company begin to offer owners of the iMac 27-inch with either the 3.1GHz Core-i5, (or 3.4GHz Core-i7 processor), and who originally paid to have their machine’s graphics processing unit replaced before the program was announced, a refund of the amount spent to get the part repaired (or replaced).
