Denon Prime 4+ FX Screen Not Working

Hello,

Under the FX1 & 2, the screens above each of the 4 knobs no longer display any text.

It was working since I’ve upgraded to 3.3 but it has stopped working. I’ve tried factory resetting the Prime 4+ under Settings-> About/Update → Factory Reset and the problem still presents itself.

Is my Prime 4+ broken or is there some setting within the menu I need to adjust? Thanks

Edit: here’s a video of the issue

If you install the previous version (3.2.0), will the OLED displays work again?

No this did not help

Just take it along to an authorised service centre.
