I don't know when it started I just remember that i opened the lid today and saw it with the stripe already.

As far as I know, it's not a GPU issue because connecting it to an external display does not show the problem... and I've tried plugging and unplugging the display cable (no results) so not sure if there anything else I can do before I consider buying an used screen.

Any help would be much appreciated!

Thanks for the quick reply guys!

Just for reference I literally opened the MacBook, cleaned and reconnected the display cable.

I'm somehow puzzled because yesterday was just fine, I played some games today and after waking it up it was just like this...

You can try to check the cables, but seems like a new LCD to me...and as you would know...they are very expensive.

How do you check if it's the cable if you don't have another cable?

By the way it's funny that I actually passed the Apple hardware test (both the fast and slow one) and it found NO troubles. Could this be a software related issue? Or is it just Apple hardware test trolling me?

I also realized than when I power up, the line looks kind of white and then change a to black. But I guess it can also change based on wallpaper or background.

You are going to have to order another cable im afraid if you want to be sure.....
Pretty sure the hardware test was trolling you........
I've seen this before and it's pretty certain it's your LCD.....

Thanks, appreciate your input.

I'll be visiting a local repair shop soon, where they will have the LCD cable and can test whether it's the cable or the entire screen.
