Hey, got a used Macbook Pro 9,2 with an SSD in it. Really sweet laptop. However, on several occasions I am running into some display issues on boot up. Wondering if I have a lemon on my hands, what the problem might be, and what could be done about it as I really like this machine. As I said, the issue has been really intermittent. I ran the 3 min AHT and it found nothing.
