Hi all,

I have 4 front buttons and a power button:

1. The power button does not respond to a press, it doesn't function as a power button, it only lights up if the screen is on.

2. The other 4 buttons when press only switch on/off the monitor

3. I've tried unplugging the usb-c and holding pressed all buttons 1 by 1 or 20+ seconds, but it doesn't do a reset.

4. As a result I cannot access the OSD menu.

 

Any suggestions on how to troubleshoot this one?
