So this is not my computer, but my girlfriends. She was doing thesis work in the library when all of a sudden the screen to her Macbook began to malfunction. At the point it is at now, whenever it is booted up, it makes the normal booting sound yet the screen is completely black with gray bars in the center. The bars span the screen vertically, but are compacted into an almost solid gray bar horizontally.
The first repair shop nearby claimed that it was a broken screen that needed replacing, but I would like to see if anyone else has ideas before accepting that solution. Could it also possibly be issues with the integrated graphics card? Has anyone else had this issue?
And as a less technical issue, what would be required to use an external display with a Macbook Pro?
