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 will 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.
Please remember to mark Solved Posts with Best Answer. Doing so helps others and saves OCE's time to look at unsolved topics. Thanks, Steve.
