I literally have to cut the power completely to keep this thing turned off. Standby is useless as it just comes back on by itself whenever it feels like it.
I put it on standby all the time as I don't really watch much TV. But if I leave it alone for a little while, it will definitely, guaranteed, without fail, 100% of the time, sneak itself back on!
Doesn't even matter the time of day or night. Doesn't matter what I'm doing. I could be asleep. I could be outdoors. I could be playing Xbox. I could be downstairs. Regardless, when I next look at it, it will be back on! It's kinda creepy to be honest.
Welcome to the forums and for your first post - I was sorry to understand that you are having an unusual issue with your V6 box.
When in standby - your V6 box should have a red/orange light and when it is switched on it will show a white light.
The only reason it could switch itself on would be if there are updates going to the box. You can use the on/off switch on the back of the V6 box if you prefer but do be advised that when you do switch it back on fully, it could take longer to load as it will need to download any updates that may have been queuing whilst it was switched off.
