My V6 box has not been working for two days but I’m unable to get through to speak to anyone on the phone. There is power to the box and the tv. I have tried switching hdmi ports and leads. I know the tv is working because I can use chromecast through it and that is working fine. Also, the internet is working as well. I have tried rebooting the box several times but nothing is happening. I am not even getting the start up screen.
