Tony Ferguson: Try changing your aerial lead - if its kaput or has a dodgy connection, then it can wipe out certain muxes. Even if nothing has changed, you'll know its not that, and the are very cheap.

At 17km from Crystal Palace, you should get a cracking signal, so check that your actually tuned to that transmitter, and if you are, then check the rest of your system.

MikeB: Thanks for that, I've already done this. It is over 4 devices all of which were picking up the signals strongly with a splitter in the loft connecting to 2 devices downstairs and 2 upstairs so I checked all of these connections.
All were picking up these signals fine until about 3-4 weeks ago. I purchased a booster for the upstairs ones about 6 weeks ago as the signal started degrading slightly and now all have gone. I wondered if the transmitters/muxes were being downgraded as I note that ch 81 is moving today.

Tony Ferguson: Read again what you've written. You bought a booster 6 weeks ago, because the signal had started to degrade, and then things got bad on the other sets 3-4 weeks ago.

Crystal Palace covers alone something like 20% of the UK population, and there is no evidence of anything being 'downgraded' - especially since you are just 17km from the transmitter (you should have no need for a booster at that distance, and possibly not a powered splitter). A problem that lasted perhaps for 6 weeks would get picked up very quickly.

Loads of people think that somehow its the transmitter, etc. But in the majority of cases, its their own system, and the evidence would suggest the same goes for you.

Since the problem is on all TV's, start by noting the strength of each mux on each TV. That allows you to identify if its one spur thats worse than the others. But since they all have a problem, the fault is almost certainly with the splitter (power supply?) or above it. Start by bypassing the splitter - if the signal improves, then you know its that.

And then go up the chain. A TV aerial is a bit of metal, and attached to a wire just 6mm wide. Even in a loft it can degrade, get loose connections, and outside will get battered by all the weather can throw at it. And stuff goes wrong.

MikeB: Hi Mike well this morning everything back to normal with all signals returned so my guess is that the muxes were being prepared for the Channel 81 retune. Thanks for the help I was dreading having to go in to the loft and check everything.

Tony Ferguson: I admire your optimism, but have you any actual evidence that anything was being prepared for a retune?

I'm glad its working again, but I suspect you will be inspecting wiring at some point...

When Talking Pictures stopped transmitting it said it needed a retune so I came to your site (today) to find where it is.

I always do a manual tune because otherwise ALL my favourite channel lists and ALL my scheduled recordings and series will be lost (on my Humax Fox T2 PVR) - taking me 30 minutes (or several days if I haven't photographed the lists).

I duly retuned C33 and spent 5 minutes putting BBC4HD C4/7HD and C4+1HD as they were.

I then found Talking Pictures still didn't work because your list is out of date - that's 2 days after the scheduled change.

Is it your policy to provide confusing and outdated information?

I had to go to a516digital.com to find out where it really is - it took me some time to find, and appears to be mainly for engineers.

Perhaps you should use it? Especially as you are the first place people look.

If I was responsible for publicly messing up like this I would be banging my head on the wall until it bleeds.

MikeB: Hi Mike, I do hope not!! In answer to your comment no, but, all other channels apart from these were being received full strength and now these are too. The only reason that I tried the booster on the upstairs circuit was because there were two connectors to that which, as the aerial lead runs under the floorboards would not be easy to re-route. The aerial is not using a powered splitter, just a simple splitter box. Downstairs is direct and I started having problems on these last week on these channels which has now solved itself !!
