AJW: There have been a number of reports of boxes/TVs apparently freezing on particular days. I'm not an expert here, but I have noticed that these seem to be those that are on the list for firmware updates that are being broadcast at the time the device hangs.
See this page:
DTG :: DTT Receiver Downloads
Could you check to see if you have latest firmware version (i.e. the version that is being broadcast, as shown on the page I gave you a link to)? If it isn't the latest, then maybe it is updating firmware. As I say, I'm not exactly sure what these things do when updating, but clearly they will be innoperable.
A key question is do you switch it off at the wall when not in use? If so, then I guess that the first thing it does is update (at times that the update is broadcast). For this reason, leave it on at the wall overnight (or at least so it is turned on whilst the update is broadcast and for which you don't need to use the machine).

We have been getting digital signals from Emley Moor here at Dronfield since switch over. Sometime in the last few weeks we have lost C48, C51 and C52. The info says signal 85%, quality 0%. I've gone back to installation -> manual tuning (which I had to use at changeover) but that looks in order (right frequency) and there the info is strength 85% quality 100%.
What has changed? I'm reluctant to do factory rest plus full manual retune, as it was a bit of a performance at changeover, until I can be sure this will cure the problem.

Tim Searle: The "FEC" (forward error correction) of the commercial multiplexes from Emley Moor was changed on 31st January. I haven't had any issues using the said transmitter.
I'm not an expert on these things, but I can only wonder if your tuner has stored the FEC mode being used and is therefore expecting it as it was prior to the change.
The technical explanation is that the capacity has been increased the equivalent of two shopping channels.
Some receivers are easier to tune that others. There are quite a few transmitters that you could pick up when auto-tuning:
Postcode Checker - Trade View
Running the automatic tuning with the aerial unplugged might wipe it. I did this with one box and it didn't wipe anything!
If this is the case, the work-around might be to get it to tune in one of the multiplexes (using the automatic tuning sequence) by having the aerial unplugged for most of the scan except the target multiplex.
Looking at the list of transmitters on Digital UK Trade View predictor, try to pick up Ch51 (or Ch52). Then manually add the rest.
Some receivers will give the UHF channel numbers as they scan them. If it's a percentage only scale, then calculate it on the basis that it starts at channel 21 and goes up to channel 68.

Denise farnaby: When you say that the TV goes off are you meaning that if you try to select another freeview channel that nothing happens?
I would like you to try two things (1) the next time it goes off dont touch anything except to take the aerial out and then plug it back in again, and if this makes no difference then (2) switch the set off, wait about a minute or so before powering it up again and see if it comes back on again.
However irrespective of the outcome of these tests could you please indicate the model number of the TV.

Denise farnaby: Also meant to say that when you are trying the aerial out then in again test, try and observe the TV's screen whilst you are re-inserting the plug to see if the picture briefly comes on then flashes off again, as if it does that can indicate that the signal is slightly too strong and is overloading the tuner, because with you being located at only 11 miles away from the high powered Emley Moor station this is something that can happen dependant on the type of aerial system you have.
If this is the cause then an attenuator will have to be inserted in line with the TV's aerial socket.

Sometime over the past few weeks we have lost C48, 51 and 52. They were working fine after switch-over but we don't watch them much so I don't know when they failed. Signal strength is reported by the ETB to be about 76% but quality is zero. However, when I go to install, to start a manual tune its says signal strength 76% quality 100%.
Why should they be different and (more important) how can I get the signal back?

Tim Searle:
Dave, Thanks for this. I somehow failed to find your reply, which seems to fit the bill in timing, before I sent a second post with a bit more detail. This discrepancy between the install signal monitor and the ordinary signal quality one - could the FEC change explain that?

Is there a connection between the FEC and the Mode or the Guard Interval? If so, to what values should I set them? They have always been on auto in the past.
