Just for reference the on / off button at the top of the nowtv smart voice remote controller is for switching your television on or off from standby and is not designed for switching on or off the stick has you have found out.
If you have the 1 touch feature on the stick ticked in the stick menu settings (default), then one press of either the home button, back button, direction button or OK button on the nowtv remote controller will automatically switch your television to the correct HDMI input source connected to the stick ready to watch.
Should the 1 touch feature in the stick settings be disabled, then you would have to select the HDMI input source on your television remote controller to see the nowtv homepage screen.
I have the same problem with stick and haven’t watched NowTv for months. Would cancel if they hadn’t given me two months at £1.50!
I ha e had to do the same thing, turn off at socket, wait, then try again. Sometimes it take 3 attempts. I have a Samsung.
I note the blue light flashes when not working and is steady when it does. Changing HDMI ports makes no difference.
I wonder if the box would be better?
I have the same problem too & not found a solution yet. I power the stick from TV USB not wall socket.
It looks like it is all about waking the stick up - remote works fine once the stick it awake. But no response from the remote until I unplug the USB power cable (or unplug the stick from HDMI port).
I've gone into setting and switched off the auto power down, after 4 hours - see if this works...
But if anyone else finds a solution - please say!
Not every TV USB socket has the welly to run a NowTV Stick, especially if you have the sort of TV, like mine, that powers down its USB when the TV is in standby, so it has to start the Stick when you put the TV on.
Try your Stick powered from the supplied mains adaptor, at least as an experiment, and see if that fixes things.
To be comparable, try it sometimes with the adaptor switched on at the wall only when you put the TV on, so it’s more like the situation with the TV, if it powers off its USB sockets when the TV is in standby,
The way the remote works with the TV is different from the way it works with the Stick.
So you could have a faulty Stick, or you could have a faulty remote, or it could simply have come unpaired from the Stick.
Furst, try new batteries in the remote.
To eliminate any temporary issue with the Stick, press the reset button on the side of the Stick, while it has power to it, for just over 15 seconds. Then set it up again.
See if that fixes things. If so, great.
if not, then try pairing the remote with the Stick again, in the normal way.
If still no go, take the battery cover off the remote and press the button you see there for just over fifteen seconds, to reset the remote.
Then try pairing it again. If the Stick now works, you will probably have to re-pair the remote with the TV also.
If still no go, the last thing you can try is downloading the Roku Remote Control app to a smartphone or tablet, and see if you can control the Stick from that.
(There is no official NowTV Remote app, but Roku make the NowTV Sticks, so their app works fine).
If that lets you control the Stick, you have a faulty remote.
If it doesn’t, you have a faulty Stick.
