Incompatibility of Firmware PKG4.017EUA with Yamaha Avantage Receiver

[monsieur_cousteau]

Hi all

I have a Sony Bravia KDL-46NX725 TV. Attached via HDMI is a Yamaha Avantage RX-A810 Receiver.

Now, since the firmware upgrade to version PKG4.017EUA, I have the following issue:

The change of settings on the Receiver (e. g. Volume changes or change of DSP Program) are no longer displayed at the bottom of the TV Screen. Instead, I get a grey, flickering bar.

With earlier firmware versions, the settings were displayed properly on the TV Screen when watching TV.

Anyone experiences similar problems or knows how to downgrade the firmware ?

Or is there a firmware upgrade in the pipeline ?

Thanks in advance.
