P JONES:
The BBC had reported the transmitter as off-air on a couple of occasions since storm Arwen, but it ought to be on air now.
If you retuned when you had no signal or badly pixellated pictures it will most likely have cleared the correct tuning and you'll need to retune again when signals are normal.
Having done that, if you still don't have S4C and if you do have ITV1 ITV2 Ch4 and Ch5 etc. the problem may need to be advised to S4C. Post back if you still can't get it and check if any others are missing.
