Is this "flickering" monitor permanently broken (see video)? Is there anything I can do to reset the monitor without seeing the menu on screen? Some button combination?

- There are no cables attached

- I made a firmware update which didn't help

- In the video you see that I press the left and right button to enter the "check menu" as described in another forum post.
