check all your connections including trying a different HDMI cable if possible.
try retuning the box, first with the aerial disconnected to lead the memory and then with it back in, unless from what you say you can't even see the settings screen.
if the does not work,
Have you tried a soft reset? To do this hold the power button on the front for around 10 seconds and the box should restart. Alternatively, you can turn off from the back and power back on.
If this doesn’t work then have you tried a YouView Maintenance Reset (https://community.talktalk.co.uk/t5/Articles/How-to-find-maintenance-mode/ta-p/1429347)?
Try the Factory Reset keep recording option.
You will then need to reset your personal settings (such as parental controls / RF loop through / Surround Sound etc.) and also reset your scheduled recordings (might be worth taking a note of future recordings before doing this so you don’t miss any).
If all else fails then try a full factory reset from the settings menu. You will lose your recordings but you may be asked to do this before the OCE look at other alternatives.
Hope it works but if not then please let us know and I’ll flag for further assistance.
Thanks fr8ys for reply.
Before trying your suggestions this morning , I switched on box and got into settings and checked software version and found online that there were a couple of recent updates so did this and the box now seems to be working normally. Hopefully it will keep on doing this. However if I have more problems I will try your suggestions. Thanks again.
Glad to hear this is working normally now.
