Help Firmware version of Denon 3910

[Lakes_Puma]

After a recent post I aksed my local dealer to upgrade the firmware of my 3910, they got in touch with Denon and got a copy of the firmware sent to them, which they then applied to my player.

The only thing is I now can't get the player to display its firmware version, I have tried several times with the method that worked before the upgrade (power on with play and open held down remote codes etc) but to no avail.

Has anyone come across this or can shed any light on the problem?

Thanks
