Apple will issue refunds to customers who previously paid for an iMac display hinge replacement or repair, according to a recently updated service document internally distributed to Apple Authorized Service Providers and obtained by MacRumors. These repairs could often cost upwards of $100 based on user complaints.
Apple’s service document acknowledges some 27-inch iMacs shipped between December 2012 and July 2014 may be affected by an issue with the display hinge, resulting in the screen no longer adjusting and continuously tilting forward. The issue appears to be limited to late 2012 and late 2013 models in particular.
The issue has been frequently reported by dozens of users on the Apple Support Communities, MacRumors discussion forums, and elsewhere on the web, with a number of iMac owners describing a similar experience in which the hinge makes an audible popping or cracking sound and then stops working.
