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 lightHave tried holding Command-Option-P-R startup as suggested in another thread Have plugged a HDMI cable in to a TV, but nothing shows Can anyone have some solutions thanks.
Sadly, your logic board has an issue. You’ll need to pull the board to inspect both sides MacBook Pro 15" Unibody Mid 2009 Logic Board Replacement. You might be able to see a burn’t component. Compare your logic board to the images here. If you see something take a picture or two and post it here for us to see Adding images to an existing question Bottom (what you see)
