Is my display broken or the graphics card?
The display on my MacBook has gone dim and has a big vertical chunk down it that is totally black and some other vertical lines.
I opened it up to see if the display connector was loose but it is not.
I also tried connecting the displayport to the HDMI on my TV but that did not work.
I am happy to replace the LCD assembly but i dont want to buy one if the problem is on the main board somewehre.
Is this a good question?
