Sharp LC-32P70E TV: EPG suddenly not showing. 2 problems, maybe connected: 1. Trying to set up

Question

2 problems, maybe connected: 1. Trying to set up for recording for tomorrow and next day - but no programmes showing in the TV Guide past today - just blank spaces where usually we see the names of programmes to come. Help, please! Just suddenly happened evening. 2. Earlier today, trying to set to record from BBC Radio 3 later in the day - in preparation, no sound on Radio 3 or 4, but all other radio channels sounding normally. Recorded it, but no sound at time either. Thank you, Sandra Brown
