Red Vertical Lines on Screen where Black Areas should be
My 15" 2007 Macbook Pro started displaying Red Vertical Lines on Screen where Black Areas should be.
I've tried some things to try and solve it, but none worked:
- Did a PRAM and SMC reset.
- Checked the connection on the Display Data Cable
- Replaced the entire Screen Assembly (including inverter, lcd, and all cables). Got the parts from a similar MBP from a friend that has a dead logic board.
The only reason I'm not sure if this is a Logicboard/GPU problem is the problem doesn't occur on an external screen.
Does anyone have any idea what more I should look into?
Is dit een goede vraag?
