I was flicking though my channels the other day and noticed loads of them had vanished - c4+1, ITV 2 and quite a few others. I did a new scan and they all reappeared. However just noticed tonight that they have all gone again? Anyone got any idea whats happening?

Got the same problem - usually relates to ITV, Five and the C4 channels.

Haven't a clue, usually just do a re-scan every morning.

Have you checked signal quality?

I'd hazard a guess that maybe if your signal gets lost then potentially the channels might disappear from the epg during housekeeping.

Signal quality is always around 80% on the channels that go missing for me.

80% quality? You should call out an engineer! (Or did you mean 80% strength?)

Check to see if there's any common element like frequency band and polarity. Loss of a band or polarity could be a lnb problem. Loss of transponders around a specific frequency might be local interference (Wifi router) or water ingress. into the coax cables. Does the epg entry just disappear or is it just missing entries ?

That usually means you can't get a decent signal from 28.5E. What signal strength and quality do you get if you manually tune to 11426 H.

Could well be strength but I hardly ever use the freesat box except to re-tune it every morning ! Will check tonight as to what actually is 80%.

Strength is worth nothing its quality that matters. You can have 100% strength but 0% on quality.

The fact you only have 80% strength is very worrying and potentially indicates your way off alignment.

Can you post your quality reading here?

That may be a tad OTT. 80% may be OK for the box he is using (whatever that is). But you are right, it is the signal quality that is important.
