I have a 506XDE which has been ISF calibrated. I have a query which perhaps anyone familiar with the XDE Pioneers might be able to answer for me. Say I am running the system under AV mode ISF Day . I then turn the Plasma off (i.e. into standby mode). When powered back on, it always starts in Standard mode. Same behaviour with all inputs. Is this normal behaviour - I would have thought that it would restart running the AV mode that had been in operation at shut down. Not an end of the world scenario, but irritating none the less. I'd be interested to hear how other folks XDEs restart. Thanks, Mike.
