Got 3 v6 boxes and its not unusual to wake up in the morning and find the box on.
New issue is that when you get up in the morning there are no lights on the box at all. Expect it to be red for standby or white, if it is on. Two of the boxes have done it in the last week on different days ie, no lights nothing, like its been turned off at the mains. Does not respond to the remote.
Flick the switch on the back from on to off and back to on and it eventually restarts after going through the normal setup routine and have been working as normal ever since.
