Happy mac chime but the screen is black completely, Please help
I have a pristine MacBook Pro mid 2007 15” A1226 2.40ghz with NVIDIA GeForce 8600M GT 256 MB. I hear a chime but no video, i have tried smc and pram reset and nothing works. I also tried booting it off of the original Mac OS X and the screen does not change just black, but no lines. I took it apart and i cant see anything broken or loose. I can’t figure out what’s broken in it, Please help.
Thanks,
