I have an HD-Dac1 which I think is excellent, but the display has stopped working, it is blank. Sure, I occasionally used to toggle through the Dimmer settings but now it is blank and stays blank. I would say the remote still works as it operates the other functions OK and acts as if it is toggling through the various Display Dim settings. I can just no longer see any display.
I guess it is a dot matrix display rather than a bulb replacement, so the question is:
Is there a factory reset routine I can apply, remembering I have no display to keep me right as I go along?
Is there firmware I can re-apply somehow?
(Windows or PC software is not relevant here as I only feed the Dac from my CD player (coax digital) or from my streamer (optical).
Thanks folks.

I would contant Marantz customer support. Maybe they can offer a repair.

I've done that now thanks. The unit is second/third hand and otherwise works fine so I wouldn't ship away for repair. I can live with it if I have to but would be hopeful that a factory reset might sort it.
