Our digital signal for ITV has disappeared in the last week - can you tell me why and what I can do to restore it

Our digital signal for ITV has disappeared in the last week -
published on UK Free TV

Sometimes people experience problems with the ITV/C4 multiplex (and also the one that carries five) because of the different transmission mode that allows more channels to be carried, but reduces the effective signal strength.

Freeview modes

This can sometimes cause problems when the weather changes (due to the inversion effect).

If you rescan for channels on your box and don't get the ITV/C4 services restored, then you may need to get a new Class I aerial to get reception all the time. However, you should check your cables and connections are in good order first.

Hi - lost ITV1, C4, C5. Muswell Hill, N10 area.
Do we need to readjust digital aerial?

Tom: No, just retune. The services were turned off during the night (and will again tonight) for testing of the new equipment. My Freeview box has no EPG, is blank on FIVE, ITV3, ITV4, ITV2+1, has no sound or the channel line up is wrong | - independent free digital TV advice should restore.

Cor blimey! Props to you or whatever's the vernacular!

We had booked a company to fix our digital aerial on the Monday (Nov 7) after I'd posted above. In the meantime I kept retuning the TV (brand new, btw partly bought because of the egregious reception in Muswell Hill); and on Friday, lo! ITV et al returned, though (Freeview) ITV breaks up/is unwatchable (again), so we use the analogue version of ITV.

Then I belatedly checked my post/your reply only to discover:
1) Theyd switched off the mains, as it were: QED the loss of ITV, and (ipso facto);
2) A retune was the answer not an aerial twiddle and its accompanying £50-£100 bill!

. .
I wonder how many people go cable and/or fandangle their aerials because of this nonsense ie, poor service, and even worse communication.
We've had many, many problems with ITV over the years and even replaced our (not very old) digital aerial a few years back. Yeah, we pimped our ride, so to speak, with a bells-and-whistles new digital aerial only to find theyd put dodgy retreads on a Porsche!

Round here in N10-land people put up with a poor service or throw money at it because they blame it on the area Muswell Hill and so let off the hook the crooks and incompetents behind the so-called digital revolution (sic). Why?
the technology must be there.
And why do the people to blame for this Fred Karno shambles create no-mans-lands of feeble receptivity by carving huge distances between masts?

Secondly, the lack of info about switching off signals ie, taking away peoples TV channels is beyond the pale, imho. My Mum watches only the main two channels and BBC News24 and has endured a patchy, fragile ITV for years only to be given the mushroom treatment from above by the TV honchos (ie, kept in the dark, and fed et cetera) about switch-offs to their (already v. poor) service. Shame on them!
. .
Anyway, moans aside! What I'd like to ask is this:
Our address is N10 3DB our digital aerial points south (to Crystal Palace?).
Come April when the new service is 'fixed' and the digital signal cranked up, will we still need to twiddle with the aerial? Where will the nearest digital signal be? Alexandra Palace? Crystal Palace? Planet Zog?!
Will we need a different/new receiver a dish instead of an aerial?
. .
Finally, I want to tear a strip off the shower behind this farce. Have you got a number for someone on whom I can vent my spleen?! Someone near the top not a poor flunky paid to insulate this seraglio of half-eunuchs from this outrage that invariably affects the old, poor and marginalised who dont have internet access to uncover this scandal and (then) post angry blogs like this!

Tom: All main transmitters have been switched to their post-switchover configuration for a total of two nights about six months before their switchover date.

It is necessary to test that the new equipment will work correctly when switchover happens.

If you think that you will get a "better service" from cable or satellite - well, wait until it breaks down (which cables does quite a lot) or rains heavily!

You have one transmitter you should use which is Crystal Palace. You should, with the correct equipment, get a perfect signal from it now and after switchover.

There is no one to complain to, the work was scheduled as part of the project plan.

this ITV CH5 problem is more than an ariel or lead issue

when retuned all programme channels are showing with great reception

however, when the freeview box is turned off
the ITV CH5 channels are lost and wiped from the channel list.

this has nothing to do with the ariel or leads because we have freeview boxes on every tv and this problem is only happening on the one box and i have changed all leads to it and used it on various tvs

i would have guessed the box is broken if it was i alone experiencing this problem

but as it is happening to others
and it happened on the week of 10/4/13

i am asking for an expert on here to advise

dave: This can happen where the receiver runs out of memory. When the automatic tuning scan is run, it scans from low frequency upwards.

Should this be the issue here, then it is probably the case that the scan has picked up signals from other transmitters (those other than the one the aerial faces) and that the desired ITV/C4/C5 signal is picked up last.

Without knowing your location or which transmitter you are using, it is impossible to suggest whether this might be a possible cause. In the case of Winter Hill, for example, all its frequencies are high up, with ITV/C4/C5 being the highest.

If you are using Winter Hill then try having the aerial lead unplugged for the first half of the scan so as to prevent it from picking up and storing any signals in the first half.
