I have both a Sony television and a Sony Digital Recorder. Having done the retuning all channels seem to be perfect on the tv.
On the recorder the HD channels the picture breaks up intermittently for about a second or two.
When I did the retuning, I did it (as advised here) on the tv without the aerial first time and second time with the aerial. With the recorder I just did it with the aerial connected. Is it worth doing it again without and then with the aerial to the recorder?
It isn't a great hassle as I can obviously record off 1, 2, 3 etc.

Big Mart: Check that the HD channels on your recorder are coming in on UHF channel 30 and not 21 which is Sandy Heath.

chris: On the basis that you are a mile or two from the Crystal Palace transmitter, it is quite likely that the problem is that the signal going into your TV is now overwhelming it. Put an attenuator inline with your aerial lead to reduce the signals' levels.
Freeview signals: too much of a good thing is bad for you | ukfree.tv - independent free digital TV advice
As a temporary measure, in order to watch television, you need to find a way to put less signal into the TV.
Some suggestions:
- A set-top aerial.
- If the aerial lead is one that screws together, try removing the outer part of the plug so that you can insert only the inner pin into the socket.
- A wire coathanger or large paperclip around 6in long inserted into the inner part of the socket may work.
- You may find that an aerial lead on its own may work, perhaps fixed to the wall.
See which of the above works the best with the BBC channels that you have. The signal strength screen should give you some idea. The signal strength screen should hopefully also be telling you that it is tuned to UHF channel 23 (which is BBC standard definition from Crystal Palace).
Having done this, then use manual tuning instead of automatic, adding each group of programme channels, as shown at the top of this page. If you find that one is unavailable (no signal), then move on to the next, noting which are missing.
As shown above (for tuning):
BBC One=C23
ITV1=C26
BBC One HD=C30
ITV3=C25
Pick TV=C22
Yesterday=C28
If, having done a manual scan of these channels, you are missing one or more, then use the ones you have to guide you as to where to best position your makeshift aerial and then try again manually tuning to the missing channel(s).
As the programme channels are in groups, there is no need to look at the rest in the group. So if BBC One is OK, then you know that BBC Two, BBC Three etc are OK as well. Stick to viewing the strengths and qualities of the above six services.

jon: Some boxes and TVs won't work after switchover, so use one that you have found to work with your other (Sudbury/Anglia) aerial.
As I suggested to chris, above, try manually tuning to the five (or six if it's HD) channel numbers. Be aware that the receiver may already have stored them in the 800s, so depending on its design, it may appear to do nothing.

For what its worth, I am in Herne Hill, and have no problems with my new Samsung TV, all HD channels are fine.
I can even get reception using just an indoor aerial, which was previously impossible.
I still can't get anything on my Media Center PCs, but Microsoft has just confessed that "We have been informed by our data providers that there was a temporary delay in data upload, but this should be correct tomorrow". So I'll try again tomorrow.

Hi, I hope someone can help. Since digital switchover on 18th April, I am unable to get MUX3 (or whatever it is now called...) so no HD channels at all.
I believe I'm pointing at Crystal Palace, and all the other MUX channels have 100% power and 100% quality, the MUX3 has 100% power, 0% quality.
I've tried TV, Topfield 5800, and a HUMAX that I know used to get me HD pre switchover.
Can anyone help/advise please?
thanks
Richard

Richard: Check that your receiver is tuning to Crystal Palace and not Wooburn which is nearly on the same trajectory.
For each of the following bring up the signal strength screen and it should tell you the UHF channel you are tuned to:
BBC One = C23 (Wooburn is 48)
ITV1 = C26 (Wooburn is 56)
BBC One HD = C30 (Wooburn is 52)
If this proves to be the problem, then when running the automatic tuning scan, unplug the aerial when it gets to 30%. All of Crystal Palace's channels are below 30% and Wooburn's are above.
On the basis that all have 100% strength, I would wonder if the signal level is too high if, having checked, you find that you are indeed receiving them from Crystal Palace. This is perhaps a little surprising as you are nearly 30 miles from the transmitter and you don't have clear line of sight with Berghers Hill being in the way.
If it is too much signal from Crystal Palace, then have you got a booster connected in there? If so, remove it or reduce its level of amplification if possible.
