Got an A1286 Macbook Pro (’09-’12, 15″, Unibody) that wont boot? Join the club. I’ll cut to the chase – it’s a video card problem with the motherboard. The problem is unfixable &, I’m sorry to tell you, Apple’s not-very-well-publicised recall has ended too. You have a paperweight. There is a reasonable market still for replacement parts for pretty much all Macs, so try your local eBay equivalent (Trademe here) to minimise your loss.
