Display flickers briefly then goes black after connecting mini dp
The display was working one night just fine until we restarted the machine. When the machine booted up, the display remained black.
I tested it on a macbook that is working with another cinema display, but nothing happened. I opened up the broken display and reattached the cable connecting to the function port on the logic board. After trying it again, it would flicker and I would see my desktop for a split second before the screen goes black.
The display is detected, is able to charge my laptop, and the rear USB ports are also working. The display will flash and show my desktop every time I reconnect the mini dp.
Any thoughts on what could be faulty here?
