"iMac (27-inch): AMD Radeon 6970M Video Card Replacement Program

Symptoms
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.

Resolution
If your iMac has an AMD Radeon HD 6970M video card and is exhibiting any of the issues described above, choose one of the following options to arrange to have your iMac evaluated:

• Apple Retail Store: Set up a Genius Bar appointment.
• Apple Authorized Service Provider: Find one here.
• Apple Technical Support: Contact us for local service options.

Before you go in for service, please back up your data. Learn more about backup options.

If the iMac (27-inch) meets these requirements, Apple will replace the video card free of charge for three years after the first retail sale of the computer.
(Update: A June 4th, 2014 revision to the Apple article extended the period to 4 years.)

Additional Information
If you believe you have paid for a repair or replacement due to this issue, contact Apple regarding a refund.

This worldwide Apple program does not extend the standard warranty coverage of the iMac.

Apple will continue to evaluate service data and will provide further updates to this program as needed."

This iMac series is referred to as "Mid 2011", although Apple revised the program article to remove that on Saturday (Aug 17th. 2013), perhaps to avoid confusion. (As of mid August 2013, they are still available at times at the Apple Store Refurbished Macs listing.)
