It sounds like your hard drive has failed.
If the following does not work, assuming you have a TV with a freeview tuner, take the aerial out of the TV box and plug it directly into the TV.
try 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 / Set antenna Out to On in Settings: Picture and Sound / 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 the full factory reset, lose recordings.
Hope it works.
