Black screen

My screen is black even when the computer is turned on. I have re-booted several times but it has not worked. I cannot see the screen to do anything.

Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379


You can also try resetting the  SMC  https://support.apple.com/en-us/HT201295


When your computer is booted up, Shine a bright light through the back of the lid, through the apple, do you see any content on screen—this would indicate screen, backlight, cable connection— and not GPU.


If you have an external monitor you can test this way as well.


In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test 


Make an appointment for a hardware issue—
