I'm confused. Aren't there non-Apple repair shops which are certified by Apple, who receive authentic Apple tools and parts and training for fixing Apple products?
Are we saying that those certified technicians can't fix it, or that uncertified technicians can't fix it, or that nobody at all, not even full blown Apple technicians, can repair it?
If it's only that uncertified technicians can't fix it, then this seems like a non-story to me. I would expect an uncertified technician to cause issues like this. Their source of replacement parts is shady - it's obviously not coming from Apple.
If it's that either of the other two groups of people (Apple certified or Apple employees) that can't fix it, then that's a real problem.
