So.. we ‘sacked’ Virgin after many years & decided to just use Freeview on the two main TVs that we use - one in the bedroom, one in the living room - the main ariel runs through the Living room Samsung (no Virgin), whilst the bedroom Samsung Smart tv had the Virgin box attached and had never been used without it. They also both have an Firecube attached to them. Once the Virgin was disconnected from the bedroom, we used a splitter to run the ariel through from Living room to bedroom (we’re in a bungalow) & all seemed to be working ok on both tv’s..... until.. i was watching a Freeview HD channel in the bedroom- on the Smart Samsung and my partner was watching - something - in the Living room on the Not-Smart Samsung.... he turned off his tv for the night & then suddenly all of my HD channels disappeared. .. So it seems that, as long as his living room TV is on then my bedroom HD channels (101 onwards) work fine - his tv is turned off (just the tv itself via remote, not the power itself, to the cube etc) then my channels just stop totally ... anyone have any ideas at all please?
