AMD Radeon 6970M Video Card Replacement Program
This has been asked several times but no resolution.
Its an issue and needs to be corrected.....
iMac, macOS Sierra (10.12.6)
What has been asked? I see no question.
iMac (27-inch): AMD Radeon 6970M Video Card Replacement Program - https://support.apple.com/en-us/HT203787 - "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."
edit: I seethe link is dead but that is not surprising. The recall program probably expired since Apple does not support hardware older than 5 years.
