Apple is going to replace faulty graphics cards in 27-inch iMacs models between May 2011 and October 2012. The graphics card recall is limited to a very small category of the 27-inch iMac.
“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.”
Apple will replace the video card for free, up to three years from the date of the retail purchase. If you can be so sure that your iMac contains the AMD graphics card, you can contact an Apple retail store; Apple authorized service center, or Apple technical support. The affected iMacs contain serial numbers with the last four characters of DHJQ, DHJW, DL8Q, DNGH, DNJ9, DMW8, DPM1, DPM2, DPNV, DNY0, DRVP, DY6F, or F610.
Visit Apple’s AMD Radeon 6970M Replacement Program website for more additional information. If you are already done with this replacement program, don’t be shy and let us know how it goes. And don’t forget to back up your iMac before taking it in for service.
Replacements can be done through AppleCare, the Genius Bar, or Apple Authorized Resellers and iMac users that paid to have the graphics card replaced are also eligible for a refund.
