A1286 won't turn on - black screen, have reset SMC, power light on

  • MacBook Pro A1286. Removable battery and hard drive.
  • Battery charges fine. LED indicators show charge level. Power adaptor shows orange when charging, green when charged.
  • When turning on, power LED lights up, the chime can be heard, but nothing on the screen (no flashes, etc.). Keyboard backlight does not light up; caps lock key does not light up when pressed.

What I've tried:

  • Have reset SMC with and without taking the battery out first; charging cable responds with green light
  • Have tried holding Command-Option-P-R startup as suggested in another thread
  • Have plugged a HDMI cable in to a TV, but nothing shows

Hi Dan. It's my friend's MacBook, and he says nothing happened to it.

Not much to work with here. There are just to many possibilities. I think you’ll need to find someone local who has a good knowledge of the MacBook Pro’s to see what they say. It could be simple or it could be expensive if the logic board is bad.
