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.

Got the same problem. I solved it by buying a outlet switch. If you turn the screen off and on for a couple of times the picture will stay and keeps on running till you switch of your machine. So it's basically just a starting problem. Somestimes it takes about 5 min until the screen finally stays on - sometimes it works at the first time. I heard from an tech student that it's related to the logic control of the screen. So he said if I want to fix this I should buy another screen panel - not the logic board, because the logic control is in the screenpanel. At least that's what he said. I took the cheaper option and just bought an outlet switch for 2€ :)

I have the exact same error, but it's intermittent and the problem mostly arises after power has been entirely disconnected from the display, i e disconnecting the power cable or switching an outlet off. As long as the computer just sleeps the display, it will often start up again.

The power supply board may also be going bad. Does it work if you unplug power for a few minutes and then plug it back in? Usually it will work for 2-5 minutes and then the display will go black again.

Sounds like the same problem I had. See:
