no display recognized, external dispay works
I'm not a rookie at things, but I bought this 17" macbook pro 1,2 on ebay. it had only a 120GB hard drive, so i tried to upgrade. This did not go as planned (whole other issue), so i put the original HD in and started it up, got the sound, keyboard lit up, but no display. Connected to external monitor, and everything works fine.
Any ideas?
