Unfortunately that's not fixed it.
Yes, that is very odd. One possibility I can think of is this being due to something unusual in your set-up. You don't have a MIDI device running MIDI Clock into the H9, do you? Or is a DAW connected to the H9?
Another possibility I can think of is that maybe there was an error when the H9 software was installed on your H9, and reinstalling your H9s software might help. It happens very rarely that there's an error installing the H9's software, but you see the strangest behavior when that does happen. When you turn your H9 off and on again does the display light up immediately or is there a 10 second delay?
