Problem description: P2415Q, the screen is now always black, though power LED is on and PC detects it. The first week the monitor was working without issues. Then after a few days break it was again attached to the computer and then the screen suddenly went off and on (with few seconds in between) and it happened a couple of times. On third time the screen never came back. It always stays black. Hard reset did not help. Monitor’s system menu is not visible either. Computer still can detect it (and switch resolution).

Details:
* The monitor was purchased two weeks ago from Amazon.
* Serial number: CN-0D8VXF-74261-71S-083L and the revision: A04.
* Connection: computer mDP out port --> mDP to DP cable --> P2415Q DP in port (using original cable from the package).

Is there any solution which I could try locally? It is quite new monitor (produced in 2017) with the latest revision (I assume) A04. Does that problem still exist with this revision? Any hints are appreciated!
