'''If an external monitor works''' fine ''you can rule out the VGC and logic board, ''look into the cables and the LCD screen itself. If the unit was damaged (dropped or screen forced back to far - weak or loose hinges) the display data cable could be cut/nicked or loose. '''Overheating of the CPU''' can also sometimes cause this... clean the inside and inspect the video cable. ''If this answer was helpful'' '''please remember to mark it accepted'''.
