Hi @Anonymous User
Do you mean the HDMI input source on your television is blank and saying no signal (which normally is a HDMI issue, where rebooting the NowTV device by unplugging the power for a minute usually fixes it or try another HDMI port on your television or a different HDMI cable).
Or do you have the NowTV Smart Freeview box and there is no Freeview TV channels available to watch, where i am guessing you have checked the aerial connection and tried a TV retune of channels in the box menu settings ?
