    Freeview, but no Freeview HD?!?

    Got a new telly at the weekend that has Freeview HD built in to it. I can get Freeview absolutley fine through the roof aerial - have been able to for years. The Freeview website says that Freeview HD was switched on for my postcode back in December - but the TV ain't picking up any of the HD channels.

    Any ideas, HUKD tech boffs?

    Ah ok - I'm using the auto tuning function - you think it may be missing the tuning channels out that might be carrying the HD channels?

    It's an LG...

    and what area are you in? e.g. whats your transmitter?

    Good question. Is there a website I can go to to find out? I see on other forums, people have been able to find out where their local Freeview transmitters are, and which of them broadcast Freeview HD. From that I can work out whether it's signal strength that's letting me down, I understand...

    Hmmm...I'm about 27 miles away from three transmitters, which kinda puts me in a medium-strength signal area. I don't really understand the whole thing around mutliplexes, so it's hard to compare signal strengths. The HD signal to my postcode is better than some of the SD signals though, and I get all the SD channels ok...

    One other thing, the aerial cable into the telly goes through our Freeview HDD box first - is this going to be compromising the signal strength?

    Are you trying to watch through your HDD box tuner or directly through the tv tuner?

    Yeah - let me be clearer...

    * Aerial comes out of wall into back of Freeview HDD, which picks up the standard def channels fine.
    * Aerial then comes out of back of HDD box into back of Freeview HD TV. TV picks up standard def channels fine, but no HD channels.

    Do we think it's likely that running it through the Freeview box first is weakening the signal enough for me not to be receiving the HD channels by the time the aerial lead makes it to the back of the TV? I need to try it and find out, don't I?

    split the cable before the box and it should work fine.

    where's the HDMI cable

    I wouldn't have thought that runnning it through the box would neccasarily cause you problems, however it will be worth looking at which way your aerial is pointing, and therefore which transmitter you are ACTUALLY on.
    I know of several cases where although their 'postcode' is capable of receiving FreeView HD, the aerial is actually pointing at a non-HD transmitter.

    Tony D - ta for that, I'll try it, but then I'm sharing the signal between two devices and therefore weakening the signal going to both, aren't I?

    Darren - no HDMI cable required, the Freeview HD tuner is built into the telly.

    Funder - I didn't realise that you have to 'point' an aerial...I may try that as a last resort, but I don't relish going up in the loft, taking the bracket down, and moving the aerial around. I fear I may end up with no better than I have now, which was best by a country mile when I first put it up. I'd rather have all the Freeview channels than get the HD channels and mess up the rest of my set up. I'd be happy for the footie, but the Mrs wouldn't be!

    Don't " split your cable " you will lose signal by doing that.

    I suspect that your aerial is focused on a non HD Freeview Transmitter.

    the transmitters polarise the signals as well so you can only pick one up at a time. So if you change it to face a different transmitter make sure you have your ariel the correct way to recieve that signal.

    whats the model number of the TV .. ?

    Care to expand on what you mean, that made no sense whatsoever to me?

    I think if it's pointed at a main transmitter then it'll be horizontal, if a relay transmitter it'll be vertical.

    Put your postcode in ]this website (tick the 'in the trade' button) and it'll show you the local transmitters. It will give their bearing from you so you can work out where to point. I think the last letter (H or V) gives the polarisation.

    Well, I went up in the loft, tried moving the aerial around to every corner...pointed it in every direction, and held it horizontally and vertically. No improvement at all...put it back where it was mounted in the first place and that's the best spot. Lost my rag with it a bit, went out and bought an el cheapo booster and that's done the job. Huzzah and hurrah, HD for the World Cup

    I recognise I should roof mount the aerial, and I recognise I'd get more gain with a better aerial, but am looking to move before the end of the year so wasn't gonna fuss around with that.

    Thank you all for your input - there is much genius going on around here...!!!
