Does this MacBook have a screen or GPU problem? This is on an Early 2011 Macbook Pro 17" with i7 2.2ghz and the Intel + Radeon HD6750: 



If it is a screen error then I don't mind fixing it myself, but if the GPU is the problem, I'm worried I might have to buy a new logic board assuming I can't use the GPU.
The folder with the question mark means it cannot find a bootable system.

That said, because it can display that image, then I would think it is a screen problem - does it show signs of being bent or having dents in it...

Are you sure of your skills to do the necessary repairs or is this a "throwaway" project...
