Macbook Pro Early 2015 13" Retina suddenly dead, no response
Do you know if the computer is booting? When you click the home button do you hear the start tone. If you think you had the volume muted, you can do a pram reset which will reset the volume settings, etc..If it boots, to figure out if it’s the physical screen or the system, try plugging the computer in an external monitor or a TV to the HDMI port.
