Missing EPG

Have you configured it to be based on a favourites list? If so check to see if said list contains any channels, if you've done a retune recently it may have cleared it out.
No retune recently.

I have a fav, list but have not made a check for a number of days but was choosing programs from the list on the tv and didn't notice any change.

A check now shows no fav. list entries. An attempt to use the fav. list backup has not worked.

Basing the EPG on 'none' brings back the list. Reverting to the fav. list removes the EPG contents so that is the reason why no EPG. Thank you.

Now the question remains, why does the fav. list backup not work after a reboot?
