The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Crystal Palace (Greater London, England) mast?

I just found wooburn's page, Wooburn digital TV transmitter | ukfree.tv - independent free digital TV advice and it says channel 52 for Mux3, and that tells me 69% power, 0% quality
Checking Wooburn's Mux2 channel 56, I get 70% power, 37% quality, Mux1 channel 48, I get 77% power, 86% quality.
All the other Crystal Palace Mux channel numbers are 100% power and 100% quality
thanks

Mind you, checking my postcode against ukfree.tv site, it reckons I should be getting from Guildford :)
Checked its channel 40, and 29% power 0% quality
So it definitely isn't finding that one!
Reason I tuned manually was because I was finding other transmitters, with poorer signals, and having multiple versions of each programme channel.

Dave Lindsay: Thank you for your response. Presumably the signal for the recorder must come from the same place as the tv, as the aerial is plugged into the recorder and out to the tv. I have a Sony SVR-HDT500 Freeview+ HD Recorder. How would I find which channel it is tuned to?

Richard: If your receiver is finding other channels, and those channels fall outside of the range used by Crystal Palace, then you can avoid them by using the unplugging aerial trick I mentioned.
If there are other transmitters that are within the "target" of say 21 to 30 for Crystal Palace (I allow a few channels either side to ensure that they're all picked up), then you may have to revise your plan.
I don't have first hand experience of these Humax devices. However, I have read that when tuning some HD tuners you need to select the HD mode when tuning in the HD channel, that probably being "DVB-T2" as opposed to "DVB-T" which is for standard definition.
I wonder, if you are doing it manually if you have to set the mode manually and that it does not automatically assume the correct mode. This would perhaps explain why it does find a signal, but just no quality.

Janice: I've sorted my problem. The distribution amplifier that I was using was analogue only. Changed it for a digital one, £13 from Argos and have all my channels.

Dave, had a few mins spare (mrs not ready to go out) and it was as you said DVB-T2 - so that's the Humax sorted, now need to try the TV to behave :)

Kate: Sorry to hear of your continuing trouble.
When you ran set up for your TV card did you select Crystal Palace as the source? If so, and your card now can't find any thing it is probably that the software is not looking for the channels in their new frequencies. Try selecting "Any source" or "All" when scanning.

martyh: Regarding the possibility of software updates rectifying this problem, unfortunately the answer is in my opinion no! as rectifying these type of issues generally has to be carried out via RS232 socket transfers or directly into the appropriate test pin area on the PCB if factory updated, that is "if" the manufacturers provided the software for such an action in the first place, something which I very much doubt as the problem would not have been known about then.
That of course being the norm with any digital receiving device hence the reason for the constant stream of software updates one hears about, and the greater the number of updates seen for the same model an indication that the previous one was, to put it, "a shot in the dark" in an attempt to cure whatever defect it was intended to correct.
Your problem does though have slight similarities to a much later manufactured range of Sony TV's that suffered switch over instigated problems, Sony's answer to the problem was to provide users affected with a software update on a £15.00 refundable deposit flash drive to be inserted into the offending TV's USB socket, but to my knowledge Sony is about the only company that has used this procedure.
I have to admit, that I personally feel that the only way your problem is likely to be overcome is by replacement of tuner, the problem there being the cost of such an action would likely exceed the cost of just purchasing a Freeview box and coupling this into the TV's scart socket, or if you didn't want a Freeview box to be seen then use one of these small wedge types that fits directly into the TV's scart socket.
As I am rather curious about this problem from my own point of view, and at the first opportunity I fully intend to check if the TV tuners part number is different between the 05 suffix models and the models without, as that would give a clue if Philips had fitted updated tuners in some later models, so maybe you could let me have the TV's serial number as hardware update notifications on service sheets use that info to indicate when a switch was made.
Regarding the use of the old Virgin box, if you are referring to the original Virgin "Free TV" branded box then its worth giving it a try connected as you have mentioned plus a scart lead coupling between the V box and TV, but its really a hit and miss thing as the tuner spec I have on these only gives the very basic of information and so you might find that it doesnt work for the same reason as your Philips.
By the way, this is a link for one type of scart Freeview receivers I referred to, but there are a few other brands available as well.
