My Macbook pro Retina 13.3inch , works fine before I updated to 10.10.3 version . After upgrading , it tends to turn black screen every 10-20mins by itself even after I turned on "never turn off the display".
I Tried the Command option P R method it didn't work .
When I start up my Mac , the keypad is light up , chime could be heard. But the screen is black .
Pls advice .

Hi EllenMa,
Welcome to the Apple Support Communities!
I understand that you are having intermittent display issues on your MacBook Pro. You have already completed a great troubleshooting step by trying to reset the parameter RAM, but the issue continued. To continue troubleshooting, I would suggest reading over the No video or no signal, image distortion, "snow," or flickering section in the attached article. Please work through the steps outlined in this section including resetting the SMC, resetting the resolution, and starting up in Safe Mode.
