We are using V6 box. We go into on demand, use search, find what we want to watch, that’s when the problem starts, press okay button, screen goes blank and then returns us to search. Have spoken to virgin this morning and they said phone back tomorrow if it’s still not working tonight. It works during the day, but stops working in the evening . Strangely after speaking to virgin today, we realised our pin code had been reset back to the default 4 digits!!
