The symbol shows the location of the Crystal Palace (Greater London, England) transmitter which serves 4,490,000 homes. 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 live in Teddington, Middlesex. I have direct line of sight to teh Crystal alice transmitter. I am using a PC with Windows 7 Media Center for all m TV viewing/recording. My freeview reception is generally rock solid, but recently I have been seeing occasional picture breakup on BBC One HD and one or two other channels. I tried re-tuning, but this does not appear to have fixed the problem. I believe my areal and cable are good.
I notice that the BBC One HD Mux is on low power right now, is that likely to be the problem?

Ben Hughes: The pre-switchover HD service is on the same power level it has always been on.

In your area, you're expected to be practically certain of having reliable reception. Check that you aren't overloading anything. If you have a booster, remove it. You could also try adding an attenuator to reduce overall signal levels (you could well need one after switchover).

Also check for possible sources of impulse interference. Keep your phone well away from the PC and the cables. Check whether the breakup occurs when the central heating thermostat or controller switches on or off. If it does, a cable upgrade to satellite-grade cable may be worthwhile.

The broadcasters' definition of 'reliable' is 1% errors over time. Nothing is totally guaranteed. Still, it's more likely to be too much signal than too little.

damo: It is your equipment. I've been using Crystal Palace fine all week, and I'm much further away than you are.

If there are any boosters, check that the power supply is on and working properly. If you can, remove or bypass them, you shouldn't need one where you are.

Otherwise I suspect a broken cable or connection.

Problem: serious picture break-up on ITV3 and others in MUX A, since changing from Sony DVD recorder (acting as digibox) and CRT TV, to Sony flatscreen (integral digibox)last week. Good ITV3 reception via DVD recorder to AV1 input on new TV, but then can't watch-ITV3-record-another. Aerial lead direct to TV, still v poor picture.
Roof antenna (Crystal Palace Tx) serving five flats via communal booster. If the signal is too weak for the TV, why is it OK via the DVD recorder?!

Yes, I've already looked at these - it doesn't seem like interference (isn't intermittent); only device attached is the DVR, and bypassing that (as I said previously) makes no odds. I've now added surge-preventing mains distribution, with no improvement. Another observation is that another ('portable' CRT Sony with cheap external digibox) TV in another room (same aerial system) receives ITV3 perfectly. Is the tuner in our new Sony flatscreen less sensitive than the one in the DVR or in the cheap digibox?

Brian King: It could just be that the Sony is less sensitive than a Freeview box. If this is the case then the obvious answer is to get another cheap Freeview box until switchover.

It is probably worth checking you've got really good quality "fly leads" as these are often the source of problems.

Often expensive freeview boxes can have worse tuners than expensive ones. The other thing is, as Brian says, to use proper quality flyleads otherwise radiated interference from the TV ot near sources can ruin a signal especially is the S/N ratio is not too great.

Brian King: As has been said by Briantist / Matt, some devices are more sensitive than others, but an easy way to even this out, albeit on a temporary basis, is to use a simple booster in line with the least sensitive device, as this will lift the signal to just above the level that is causing you the problem.
