Apple Cinema 24: Display turn on after 30 restarts from sleep

Hi,

I just bought Apple LED Cinema Display 24 (A1267) and it has problem with turning on. I have conneted it to my Macbook PRO with Thunderbold Display 27, every display is on seperated USB-C connector.

So the thing is that when I wake up macbook from sleep, LED Cinema 24 blinks really quickly and then goes black. If I use flashlight I can see desktop. After 20-30 attempts from waking up from sleep it’s finally power on. I also made a video what’s going on.

Does anybody have an idea which part needs to be fixed, because any service in my country doesn’t want to accept it on service :(

On page 24 of the Apple Guide, there is some troubleshooting steps I would take.This should help you at least narrow down what the culprit is.

Best of luck! Post additional information (if any) after troubleshooting!
