All of the sudden my Keylab 61 mkii display has become too dark. I can barely make out any characters on the screen. It was just fine, bright and clear last time I used it. Today I powered it up and issue started. Also if I put my ear up close to the display, I can hear a high pitch noise. I’m not sure if that is new or related, but I hear it now whenever I turn it on. I’m using the dual usb adapter that came with it. I tried different usb cables, different usb ports on the computer and same issue - can’t see anything on the display.
