Mini box stopped working and message is ‘weak or no signal’ . Have reset via this box not working

[George169]

Signal from mini box had been breaking up for three days and last night it completely stopped . Have unplugged and reset the mini box and main sky q box and still tells me 'weak or no signal' .

Everything behind the tv looks as if all wires etc are properly connected .

Mine has been doing the same, I finally got it connected to the Wi-Fi on the main box but now it seems to be stuck on the home page with remote not working with box
