Hi, my NOW TV stick has stopped working completely. No white light is coming on, I've tried different plug sockets and TV's but I'm getting nothing. I have tried pressing the reset button but nothing seems to work. It was all previously set up and working without any issues so I'm a little stumped as to what the issue could be.
How long did you press the reset button for? A short press only power cycles it; try a long press (~15 seconds) for a full reset.
Bit of a long shot, are you able to try out another USB power cable?
Have you tried to plug the stick into another TV?
