I've been away on holiday for a week and before I left, all my required programmes were in the schedule. When I got back the Aura was showing a bright red light on its display, so I knew something was not right. When I switched it on, it came up on the Home screen, which is not normal. The only programmes which had been recorded were two on the first night I was away, everything else was missing. The schedule still showed all the expected series plus about 20 'broken' GB News entries, which had never been set up in the first place. After deleting all the rubbish I waited for the first scheduled programme to record, but it failed. I had to completely delete the schedule and set up the whole lot again. Curiously, when using the guide to set programmes up, the original record icons were still there despite the schedule having been cleared. I had to delete all the record icons and start again.
Having had no problems with the Aura for many months I was disappointed that it had chosen to fail so miserably just because I went away (my paranoia). The Aura was left in normal standby and was not connected to the internet.
My only thought about what might have caused the issue is that, when I go away I power off all my AV equipment except the Aura. Thus the TV, AV Amp, Sub and Bluray player are all powered off. The Aura is connected directly to the TV via HDMI, so its sound output is sent to the AV amp via eArc.
