We will need some history on your mac. Are you sure it is not booting? Have you shone a torch on the screen to make sure it is not the backlight?

I tried the torch on the back and it is not the backlight. It just won’t boot. It was my sisters and she says one day it just turned off and never turned on again. So not much help there.

If the fan is spinning and there is no image or chime it’s not a good sign. If you haven’t got another shell to test the screen I would try the following.

·         Check for liquid damage on both sides.

·         Do a PRAM/NVRAM reset.

·         Insert a bootable USB drive with a light and see if it gets activity by the light flashing if it doesn’t it would point to CPU.

·         Disconnect the battery and connect magsafe.

·         Disconnect all flex cables on the board except the 6 pin power cable and connect magsafe.

I have found with this model it’s usually a dirty Bios file or faulty CPU if the above don’t help. Most likely CPU but you would need a reputable repair shop to confirm.
