PLEASE ALL VISITS ARE BY APPOINTMENT ONLY! YES WE CAN REPLACE GPU'S/GRAPHICS CARD ON IMAC'S TOO! MacBook Pro & Retina GPU/Video Card/Graphics Card Logic Board Replacement Service If you have a 2008 to 2014 MacBook Pro & Retina models from A1278, A1286, A1398, A1502 some of these years will run into having your dedicated GPU/Video related hardware failure. If you have already run into this problem we can have your current "failed" GPU/Video card replaced with a 100% new component and have you back up and running within 3-5 and sometimes 5-7 business days! The most common symptoms of a failed and partially defective GPU are: 1) A frequently crashing system, scrambled video or distorted screen. 2) No video display on the computer screen, even though the computer is plugged into a power socket and switched on. 3) Unexpected booting or computer restart. Please make sure to call and have your serial number ready which is located under "About this Mac" if it's still running or right underneath the bottom end of your laptop. Since the serial is VERY small we would recommend using your phone to zoom up and take a picture for easy reading. www.TheMacDoctor.ca Business Hours: Mon-Fri (8am-7pm) Saturday (10am-6pm) Sunday (Closed) Tel: 613-294-5374
