I always turn the Mysky decoder off (put it in standby) whenever I'm not using it, but in the last couple days I've noticed when I've left the room for something I come back to it off and the TV still on. Now unless the girlfriend is turning it off to mess with my head, I can't understand how it could be happening.

It's well ventilated and doesn't seem hot. I have my Orcon genius modem in the same room and thought maybe the wireless is doing it, but I've had that for 12 months and not had a problem until now.

It's definitely some of of interference somewhere causing it, maybe the neighbors.
