A friend has a BeoVision8 40 connected via BeoLink convertor to a BeoCentre9000. He recently went away and powered off the TV only. On returning and powering up the TV he had lost communication with the audio system. I suggested he power off the whole system and power it on again which did the trick. The BeoLink convertor started talking to the BeoVision8 40 again.
The BeoVision8 40 doesn't have pin code protection, so if it is a standalone set, it shouldn't be an issue, just an inconvenience.
Bang & Olufsen have started supplying some products with mains cables with in line power switch to conform to these EU regulations about power conservation.
