Hey guys, So I recently picked up a macbook pro 17" MBP off CL, and the buyer failed to mention anything about this problem go figure right? ( I did test it, problem never showed up at that time) So usually when I wake my mac or sometimes at random occasions anything thats dark in color gets these blue vertical lines in it. No other color is affected by this. most times its goes away in about 10-20 seconds or by moving the MBP if not gone in the said time frame. I will include pictures when it does it again. 17" MBP Early 2009 2.93 GHZ Intel Core 2 Duo 320HDD NVIDIA GeForce 9600M GT 512 MB Ive tried googling but couldn't find anything, anyone else had this problem?
