I have no video; backlight comes on but display is black
Retina MacBook 13" suddenly has no video; apple lights up, so the backlight is working, but screen is black. Plugging in external monitor via DisplayPort shows "No Signal" on the external monitor.
Am able to ssh from another computer, but
"system_profiler SPDisplaysDataType |grep Resolution"
doesn't do anything (works fine on other computer)
Is there a video card that could have gotten dislodged somehow? Any other ideas what it might be and how to fix it?
