Issues with one MUX

[Tre4Bax]

Weirdly tonight a single set of channels associated with one MUX have decided to just show a black screen. All the other channels seem to work fine but this one does not. I have no way to check the signal strength, but I guess this could be low although it all seems to be coming in fine on the other tellies in the house despite the fact that they get a second hand (so should be weaker feed).

Anyone got any ideas?

If the TV and PVR tuner use the same aerial then you can check the signal strength of that MUX on the TV. If it is weaker than others then your signal is probably marginal with this mux falling just off the "digital cliff". It could be because that mux is lower power than the rest or the mux frequency is at the top or bottom of the aerial coverage so the gain is lower or with this wet weather some damp has got into the aerial or downlead. Also its not unusual for a mux or the whole transmitter to temporarily run at reduced power during maintenance work or a fault while using a backup transmitter or aerial.
