Saorview cutting out

Gwynston

My in-laws have recently started using the built-in Saorview tuner on their LG M2755D TV and are having problems with keeping channels "in tune" . (They were still watching analogue as they are in a poor reception area and needed an installer to fit a new higher UHF aerial).

Now when watching a Saorview channel, the TV will periodically "lose" the channel - all of a sudden all they get is a snowy residual image of the channel they were watching. Strangely, simply selecting the channel button on the remote restores the clear Saorview channel again.

This can happen quite frequently, say multiple times during an evening's TV viewing. I haven't had a chance to investigate myself, but is it likely a TV tuner problem, or can reception problems with Saorview manifest themselves like this?

i.e. being digital, if the signal quality is borderline, could the picture just cut out similar to when bad whether can cause loss of satellite reception? Or would you expect a more gradual picture breakup, with pixellation or freezing picture or something?

Snowy or fading would be associated with analogue reception, the only type of picture breakup I've seen with digital TV is a you say pixellation, freezing, a sheet of colours across the TV screen or a blank screen. Does it happen in the evenings only or anytime of the day or after the TV has been switched on for a period of time?

The aerial installer should be able to advise them.

This sounds like a tv set fault as DTT pictures should not be "snowy" and the fact that the remote brings them back.

Sounds like someone is changing the station to analogue!

I am sure you can set the Tv to receive digital only, so that it doesnt switch between analogue and digital(Saorview) .

Thanks for the replies.
So it sounds like the DTT tuner is just cutting out? (Leaving a snowy analogue image).
It happens randomly by itself any time of the day, as far as I'm aware.

I'll check the TV settings for them to see if I can deactivate analogue completely and see if that helps....

Yea I am having the same problem, I have the Saor view box and the Saor view box keeps turning on and off every 5 minutes. I don't have the snowy residual problem.

Any body else having similar problems with the box?

OK, haven't been to see the in-laws for a while until this weekend, so finally managed to sort this issue out. I should say that the symptoms I posted originally were actually reported by my wife when she was visiting - I'd never seen the phenomenon in person myself.

So it actually turns out that the signal wasn't being lost periodically by itself, it was actually during channel surfing. After having it demonstrated to me and then playing around myself, I realised that it happened if you selected the channel number that was already being shown!

The TV was storing two banks of channels against the same numbers: the new Saorview ones under a bank labelled 'DTV', and the old analogue ones (from before Saorview was set up) under a bank called 'TV'. So when you, let's say press channel 1 on the remote, there's a choice of two "channel 1's". It defaults to the DTV one, but if you subsequently press 1 again, it switches to the analogue one, which of course no longer exists!

To avoid confusion, I just deleted all the old tuned-in analogue channels, so unexpected switching no longer occurs.

I must say that this little LG set has a great picture - one of the few sub-30-inch TVs with full HD. When I bought it for the in-laws a few weeks ago, the salesman in Currys tried to convince me that you wouldn't really notice the difference between HD-ready and Full-HD on sets of that size, but watching the FAI Cup Final yesterday on RTE2-HD looked brilliant!
