I cannot receive any HD channels today. A full retune does not find any of the HD channels 50- 54. Any clues?

Mikethemix: Try manually tuning to Ch31.
It is a possibility that you won't be able to pick up HD until switchover next year.
The Crystal Palace HD multiplex does not serve as big as area as the other (standard definition) multiplexes it broadcasts.
In particular, the Reigate digital transmitter uses the same frequency, so the amount of signal that Crystal Palace throws out in that direction will be much less than in other directions. You may well be having problems because of this measure.

At about 6.00pm today, we lost all digital chanlels with "no or bad signal". We have 4 TV's in the house, one is attached to a digibox, the other 3 are IDTV/freeview tv's. We can get analogue channels (BBC1 & 2, better than ITV/C4/C5 and that is it. I have tried retuning one of the TV's to no avail. Any help?

Nicki Hardy: In situations such as that which you describe, I would not retune any TV. The symptoms suggest a problem (of some sort) with the signal. Running the retuning scan simply causes more problems because now you have to retune it when you get the signal back.
If you have an amplifier for distribution to the 4 outlets, I would check that it's powered on. Then try bypassing it by connecting the lead from the aerial to the output to one of the TVs. Then go to the TV and see what you get.
You might need an adapter to connect the lead from the aerial to the lead to the TV (wall socket) because they might be the same gender.

Re: Dave Lindsay
Thanks for your constructive suggestions. I have tried tuning channel 31 manually, looking for T2, and the STB sees nothing.
We have been receiving all four HD channels without problems since the Humax HDR Fox T2 was installed in August 2011. So this is a new phenomenon. Is it possible that the STB's HD capability has failed? (51.2855,-0.3923BQ)

I have had probelms with ITVHD wirh lip sync. I thought it was the Sony SVRHDT500B unit but all other HD channels were perfect. My supplier contacted Sony that gave him wrong info like using the coaxial audio out to the TV. This of course is no good as TV's do not have coaxial audio in. Its only there for audio amplifiers or dolby sound systems.
I contactec ITV who say there is no transmission faults at present.
I contacted Sony who said try doing a factory reset, this done made no difference. Then many hours later after trying three times;all the HD channels could not be found!
--- Answere to all of this is my aerial was split to other devices and up till Sunday night worked other than lip sync problem. This morning by removing the splitter with the down lead now going straight in to the Sony unit, the channels have now all returned and lip sync on ITVHD is not perfect still but slightly improved. My signal strength has always been around 45% with error around 26% and still is.

Thanks Mikesparky, as you suggested I discovered a wiring problem with the aerial cable - a dodgy plug / cable joint. All sorted now and all channels coming in loud & clear!
Many thanks.
