I have two Youview boxes one of which regularly crashes. What happens is the video and audio still outputs to the TV but the box becomes unresponsive and any active or scheduled recordings will fail. The only way to get it to respond again is to power cycle it.
It feels quite hot when this happens. I've tried cleaning the fan and vents, and raising the box off the surface, to try and keep it cooler but that hasn't made much of a difference. I've tried the obvious thing of batteries in the remote in case it was that but the remote is functioning fine.
We tend to go a couple of weeks without it happening but when it does happen it recurs regularly (2 or 3 times a day).
I've also tried resetting to factory which didn't help.
I'm not sure if there's anything else I can try?
Yes we just renewed our BT TV contract (a couple of months ago I think)
