I'm not sure what Virgin box we have but today we have a black screen and perfect sound - turned it on and off. Check all the cables. Taken them out. Put them back in. It happened a couple of weeks ago and seemed to right itself. But has done it again. It's a new box so couod it be that. The Fire stick works perfectlh

Take a look at https://www.virginmedia.com/care/tv-fault/which-tv-box
Do you have access to the box's menu system? How about the video preview screen?
