- Warwickshire, UK
I use 2 x digital boxes, 1 for terrestrial french tv and the other for satellite english freesat tv, both these do not have anything programmed.
My UK Freesat box (Humax) used to ‘wake up’ at 0300hrs for SW updates (channel changes etc). I am not sure how you have it connected (hdmi or SCART), and anyway B&O don’t use hdmi CEC, but I suppose there is a small chance this could be related.
Otherwise I agree with MM that the Beo4 could well be the culprit. I had one that behaved in a similar manner – working normally and then changing channels some hours later! I tried cleaning it but eventually had to replace the contact foil.
