I've been given a Panasonic TH-37PX600B and am having trouble setting it up. If I run the autosetup it finds channels in Ireland even though I'm on the west coast of Wales. It doesn't actually show any picture on the screen but I can see what's on via the programme guide and the audio works.

If I use a set-top box via scart, which is being used on another TV, it works fine.

Any ideas?
 
Edit: The signal condition says No DVB Service, even though it works through the set-top box via scart.

And it picks up RTE this that and the other

Thanks for the reply

I have ran a new installation on both the television and the set-top box borrowed from another TV. When the aerial is connected to the set-top box and connected to the TV via scart, it works as expected. However when I take the aerial cable and put it straight into the TV, I get the RTE channels, with the sound, TV guide but no picture after a new installation setup
 
I'm setting the TV up at my parent's house to the south of Blaenplwyf and from the map in the link, outside it's range
 
i think were on the Preseli transmitter and we fall into a dark green patch. We had a booster installed when Freeview was launched.
 
Thanks for the detailed response lucid. Much appreciated.

Turning the booster off turns off the signal for all three TVs in the house. Here's the setup

TV1: This had a old CRT running a Phillips set-top box. I swapped it on the weekend for a cheap LCD/LED(?) with a built-in tuner.

TV2: Again this had an old CRT running a Phillips set-top box. I have tried the plasma here with and without the signal booster. With is detailed in my first post. Without it gets nothing.

TV3: Another CRT with a set-top box. Same result as TV2 when running the plasma here.

I'll bet you a fiver that what you're calling a Signal Booster isn't actually that at all. I'm betting it's a power supply, and it sends its power up the aerial coax lead to the amplified aerial splitter. If it was a booster then turning it off wouldn't affect the signal to TVs 1 & 3. They'd still get a signal if the loft amp was powered directly from a mains socket.

Just a thought, but you have made sure that the TV is tuning in the digital services rather than running analogue tuning?

I think your right. The splitter box is outside underneath the eaves.

As for the analogue tuning question, when I choose to manually tune it scans through numbers 21 - 69(?) which is the analogue frequency from what I remember. The auto tuning finds the RTE stuff with no picture. Though some of the higher channels (Sony Movie Channel, ITV3 something) work.

When I picked the TV up it was working, directly connected to the aerial via coaxial. That was about 5 miles from the Blaenplwyf transmitter.

A good suggestion.

I had a samsung freeview tv p2270hd purchased in France that was unable to tune the UK freeview muxes, although they should have been comaptible;
I tried frimware/usb updates to the tv but they did not resolve the problem.
So I was forced to use a freeview box, this had an hdmi connection, so Picture quality was OK.

It was bought in Aberystwyth
 
Thanks again for the detailed explanation. Ordered a 0-20dB variable attenuator but can't seem to make sense of the results for the fixed level attenuator.
 
I've tried the variable attenuator on the plasma but it still found the RTE channels only. The other type is on it's way.
