Thanks MikeB, signal strength and quality varies all the time. Some days it'll be 100%, others it'll drop to barely 10%. Coax cables are all screened as are the wall plates. I'll try to test with an indoor aerial and see how that goes, I don't get why the channels are fine one day and then gone the next. If it was the external aerial deteriorating, surely it'd be getting worse and worse whereas tuning seems to be a lucky dip and sometimes I get 82 odd channels, other times it's 116.

Vic: Sounds odd, but you could have a mixture of two problems. If all your muxes are vanishing, then then that sounds like a failing system. If it comes and goes, could well be something like water in a cable - when it dries out, its fine, but its only going get worse over time.

On the other hand, 100% is far too high - see 'too much of a good thing' on this site. We dont know where you are, so cant say what sort of signal you should get, but look at the possibilities and narrow it down.

I have an aerial on roof directed to Crystal Palace. Everything has been fine for years and always update when notified of new channels. Recently we have been experiencing poor signal for BBC 1 & 2 but BBC 1 HD & 2 HD have been relatively fine. On the non HD channels the picture starts to break up but after a while it recovers. It will e okay for a few days and then the break up occurs again. Last night we lost BBC 1 & 2 completely. The HD channels are still okay as are all the other channels. Have reset / retune a couple of times and now it does not even find any signal so does not allocate a channel number to them. HD versions are still fine. When retuning we have 5 TV channels with from memory 91 total channels.

We have recently seen large "birds" hanging around on the aerial near to where the cable picks up its feed. My wife thinks they might have been pecking that termination point causing damage. I am not sure this could be the case as I would have thought that would impact all of the channel and not just these two.

Before I get an aerial person in to check wanted to see what anyone might think about what is happening.

Hi,
I can't receive COM7, CH33 in Iver Heath SL0 0PT, although all coverage maps show strong signal. I know 100% that for example Talking Picture channel 81 definitely worked on the same receiver before, now it is gone. I tried all sort of reset/ retuned without cable then tuned again, nothing helped.
My Polaroid HD model DTT 1810 shows no signal on CH33, all other CHs up to 29 have good signal.
Regards,
Alex

Alex : Whats your signal strength? If the remaining muxes are low, points to the obvious - you've got a problem with your system, and the whole thing is gradually going. Frayed cable, etc most likely reason. Start with the fly lead from the back of the TV - swapping it out is easy, cheap, and might cure it. If not, at least yo know its not that and then you can follow the signal path back.
