Sometimes, our 4K NextBox (CAV10455HD) becomes unresponsive to any UI command: remote buttons don't register (we tried both remotes); even the front-panel power button doesn't register. Meanwhile, the box continues to play live TV or a recording; it doesn't totally freeze, just the UI.
What can be the cause? I'm interested in a solution, but hopefully some explanation as well. I like understanding how my devices work. Thanks.
Thank you for posting your concern in our community.
I can understand how frustrating it is to experience this type of freezing when trying to use your 4K Nextbox. It is a bit strange that this is happening, it's not an issue we've heard much about before.
That specific type of box was manufactured over 5 years ago and could be experiencing a software issue. A factory reset may help remedy this issue but it will erase all of your settings and your recordings along with scheduled recordings.
If issues persist after the factory reset then we'd recommend an equipment swap.
I hope this helps!
