Hi everyone, so confused with this problem even as an apple user of 16 years. I have a mid 2009 macbook pro 17" 2.8ghz Started it up this afternoon, normal boot sound but black screen only?! fully boots up, sound works, backlit keyboard, dvd drive. But no screen?! Tried resetting PRAM and resetting SMC, no luck. Black screen even at boot, no grey screen or apple logo. So decided to try a hunch.... Turned on whilst holding option (alt) to reach the partition list. I knew i had windows bootcamp, so pressed my right key to move to that, pressed enter. BAM....WINDOWS LOADS UP FINE?! Infact just posted this message off it now. But OS X just won't load to a screen? I'm really confused as to why it won't even show me the partition menu at boot, even that screen is black...?????
