Sky q box is not working

[Me51]

Sky q box is not working. When I switch it on I get the following message. ' No signal. Check the external input or select another input using the INPUT button. Normally when I do this I gain access to sky but nothing presently. I have unplug the system and waited a couple of minutes but still nothing.

A message displaying ”no signal” tends to be generated from your TV and normally means your TV’s not seeing the Sky box on the relevant HDMI input.

Power down the Q and back up just in case it has crashed

and if that doesn't work, cycle through the HDMI inputs on the TV

Hi @Me51 

First make sure that the TV is switched on and is switched to the HDMI input to which the Q box is connected.
Then with the Q box switched on with green led illuminated
Press
Home 1 0 8 0 Home
on the Q box remote control.

This will change the Q box to standard resolution which will work for all TV’s.
