Since this is a MacBook Pro (notebook/laptop computer)...it could be the video cable. The video cable runs from the logic board thru the hinge area to the display...and it is possible for it to get pinched or frayed or worn...potentially causing this intermittent "black screen" issue.

This can especially happen when the laptops display is opened/closed...or the angle of the display is adjusted.

I realize that the "Apple Genius" said to just reinstall the OS...but maybe he didn't explore deeply enough. To do a complete visual inspection of the video cable some serious disassembly needs to be done...and even if the video cable looks fine...something could be wrong on the inside of the cable...which can only be determined by replacing with a new cable.

This is just a theory/possibility...the only way to know for sure is to swap cables.
