My v6 box has stopped outputting video picture. The virgin screen template shows and can hear sound but no video. I get the same with my v6 recordings. I have changed hdmi cables, still the same. I have run feed from my dvd to the same hdmi socket in my tv, and working fine. My tivo box upstairs is ok so feed into the house ok. Only conclusion is v6 box kaput. Diagnostics on the box fails, so does the test from virgin website.
