Hi all

I hope you can help, I am trying to help my elderly mother remotely, never a good idea.
She has a LG Freeview TV up in Cumbria. This worked fine after the analogue switchoff up there, but recently when she switches on the TV there is no signal on bbc1 and bbc2. when she does a retune, it brings those channels back in with all the others, and apparently both have an excellent quality picture. She can then freely move between all the channels, but once she switches off the set, they are no longer there when she switches back on.

I wondered if this was a common problem or indicates to anyone where the fault may lie, I can't find any similar posts here and the internet is swamped with digital retuning information, making it impossible to search for something like this at the moment.

We welcome your thoughts.

Possible that it is faulty. My LG certainly doesn't forget channels, even the rubbish shopping ones, much as i would like it to

I was wondering if it was switching on tuned to BBC analogue which obviously won't exist any more. The LG I have is fairly unusual in that you don't put it into Analogue or Digital mode. You can scan freely from BBC1 analogue up to Five analogue then to BBC1 digital and so on or vice versa just using the channel up down control. ie if you are on BBC1 digital and go down a channel you get Five analogue. if on Five analogue and go up you get BBC 1 digital. Can make it a bit confusing because I've actually got two channels 1, 2, 3, 4 and 5!

But if you have dialled up a digital channel and select 1 on the remote it goes first to BBC 1 digital. But if you had selected an analogue channel and pressed 1 it goes to BBC 1 analogue first. But it does have a little pop up box that lists all channels starting 1 which lets you switch easily between analogue and digital. The only difference is a little logo next to the channel name that says TV for analogue and DTV for digital. That may be an indication. If the popup that appears when you press button 1 just has BBC 1 with a little DTV logo next to it then it's on BBC 1 analogue. If however it has BBC 1 (twice one with DTV and one TV) plus 11,12 etc then it is on digital.

If it is that using the channel UP button should go to BBC 1 digital eventually. Assuming your mum's telly is similar to mine. Model number would help

Thing that puts me off that though is the retune business. Whenever I've retuned my TV it has tuned both digital and analogue (in that order). I'm trying to recall though if you can separate analogue and digital tuning (not at home so can't check).

But if it had left the analogue tuning intact then it may still have references to BBC1 etc analogue that are no longer valid, hence the blank screen. But do a retune and it reverts back to BBC1 digital at the end. Though quite why it goes back to BBC1 analogue all the time as it should go back to the last channel viewed.

I am sort of leaning towards it being a fault rather than it selecting analogue but you never know.

Thanks for your thoughts ChrisJr, I will try to explore that thought, it is really difficult doing this remotely. I guess I suspect that it is a fault, but don't want her incurring unnecessary expense if it is something trivial that she is missing.

thanks again

If you can get the model number of the TV that would help. Though that might not be so easy. If she still has the box it will be on that in big letters. Mine is a 32LH3000 and the model numbers follow a similar format just maybe with different numbers and letters.

if it is a fairly recent one then it may well operate like mine and scroll seamlessly between analogue and digital. In which case the little pop up box that appears when you press a channel number might indicate what is going on.

So ask her to press 1 when it "goes wrong" if the pop up just shows BBC 1 and nothing else or two BBC 1s one with DTV and one with TV next to the number then it is on Analogue. if it lists two BBC 1s and also ITV 3 on 10 and Sky 3 on 11 and Yesterday on 12 then it's on digital.


PS if you are going to capitalise my username get it right. it is ChrisJR

Thank you

Hi ChrisJR, (sorry thought it was Junior, no offence intended!)

Unfortunately, no model number forthcoming, the TV is a couple of years old, so no box, i have suggested she finds the instruction booklet to see if that helps, but it sounds like your theory may not apply in this case as she says there is a button to change from analogue to digital channels.

Guess this is a hands on job!

Haven't been a Junior for more decades than I care to admit to in a public forum

Sounds like it is a different firmware to mine then.

One other thought. I wonder if the other BBC channels are going at the same time? ie BBC 3, BBC News CBBC? If they are missing too then that sounds like it may be losing the BBC MUX in it's entirety. Again not so sure why it should be doing that.

If you do get hands on with it have a look to see if there is a way to do a factory reset on it. That should restore it to out of the box condition. Then retune and see if it retains the tuning info now.

It could be that the tuning table of the TV is a bit corrupt. Especially if it's gone through analogue switch off which may well have involved some UHF frequency changes on the muxes. Maybe it's got a bit of the old frequency data trapped in there somehow. Or is that just clutching at straws?

But i would be tempted to try a factory reset which should completely zap all stored data and let you start from fresh again. One other thing you could try is doing a manual tune just to be 100% certain you are receiving the correct muxes.

Not impossible that it could be getting signals from two transmitters which may confuse things. Use this guide from Ofcom to find the UHF channel numbers, assuming you know the local transmitter name of course!

Thanks again for the input, lloks like I really do need to do this myself rather than try and do it over the phone!

there will now be a short pause, until I have nipped up the M6 and back.

Cheers Duff

Hi ChrisJR

Mission accomplished! Managed to do a factory reset and all working fine again. Thanks again for your input.
