I have just changed my internet to full fibre. I had no trouble connecting my now box to the tv downstairs, however, I have just taken it upstairs to connect to tv there and it says I have no signal. Internet is working fine upstairs for laptop, phone etc. How can I reconnect my box when I can't get anything on the screen except no signal?
Best way is to do a factory reset to the box.
If @gavs82008‘s advice does not cure it :-
Are you using the same HDMI cable as you had downstairs, or at least a known-to-be-good one?
Have you ensured that both ends of the cable are firmly seated?
Have you taken the Now box back downstairs to prove that it is still working there?
You might want to try these things first, save yourself setting the box up all over again if it’s just the connection.
Yes, I have done all of those things, same cable, firmly seated, tried downstairs again, no issue there, just upstairs.
@Nanma just for clarity, what do you mean by 'no signal'?
If a Now box or stick can't connect to the internet you should still get through the start up procedure and see the apps but it will say something along the lines of "internet connection is lost" or "couldn't connect to network" along the top of the screen and the white light on the front will flash repeatedly.
If the message is "no signal" on a blank screen that would indicate that the box and TV aren't communicating.
Is the box powered up? Do you have a solid white light on the front of the box?
Have you selected the right input or hdmi channel on the TV if you have more than one hdmi socket?
On your TV remote should be a button that says 'input' or a square with an arrow through it. Press that and go through the different hdmi options.
