How can I tell if my MacBook Pro has a bad display or GPU?
My MacBook Pro Unibody Mid-2012 is having really weird distorted colors. I tried programming the Mac to only use integrated graphics and that issue was still there. Although, when I connected that MacBook Pro to my desktop mac using "Screen Sharing" the display of the MacBook Pro looked perfectly fine on my desktop Mac. Also, some "ghosting" happens on the screen. This is making me think that maybe the display is at fault because if it were the GPU, those distorted colors would show up on the desktop Mac as well, right? Is this a bad display or GPU?
Also, I had to charge this machine with a 60W Magsafe Charger while the computer was powered off because I did not have an 85W Magsafe Charger lying around. When I came back, the computer was on and it was really hot. Could this have caused it?
Update: Computer is now chiming, but the display is no longer working. It's just a black screen. I noticed that when I put a flash light behind where the apple logo is, I can see the screen dimly.
Update 2: From the looks of my research, it looks like my backlight went bad. How can I tell if this is an issue from the actual screen assembly itself or the logic board?
Questa è una buona domanda?
