Freeview issues

I've got a relatively new digital TV.  My aerial became disconnected the other day - and since then I have some weird problems with my channels.

I can't get E4, but I get E4+1.  More4 and ITV4 come up No Signal. 

I've been looking for possible causes on-line but only find old info about Freeview boxes.  The was something about 'rescanning channels' but I can't find it on my menu.

Any ideas?   

I found mine this way.

Menu button > Set Up> Auto Tune> Replace Existing Services

That's how we rescan periodically for new channels and when they move channels as well.

Hope that helps.

Thanks WebyJ, but I still can't find it. 

I did find how to check the signal, and it says I have an IO error.  Funny thing is it's all the '4' channels. 

I'm going to have to get out from under my blanket and consult my owners manual aren't I         Blarg! 

Sorry, but sounds like you'll have to go digging...best of luck!

Ok so I figured out how to rescan, and now those channels are totally gone!  No Channel 4, no ITV4, no More4 or E4.  But I still get E4+1.

Snap!  Are they no longer part of the Freeview package - or is it just my TV?

All your missing channels are on the same Multiplex (frequency). E4+1 is on a different one. This is likely a problem with the aerial (or even your local transmitter but that would probably have been fixed by now) rather than your TV. See http://www.radioandtelly.co.uk/freeviewchannels.html for a list of channels with their multiplex (mux).

Your aerial might need to be checked to see if there is a fault in it or some damage especially if the cable was tripped over and that's how your box was disconnected. You might want to try disconnecting it from your box and re connecting it. I doubt it's your TV. I know our box is having issues (all our BBC/itv channels are up in the 800's now instead of where they were at the beginning, we've been told it's our aerial or our freeview box). But we're just living with it.

Its a digital TV with the Freeview included in it, so no box  I guess that means the box is on the inside?  I've tried disconnecting both ends of the aerial cable, and nothing changed. 

I moved my TV about 4 feet right before this problem started.   Either that or my cats disconnected the plug from the receptacle. 

I guess that means that they are not deleted from the service.  But since I'm getting everything else, I'm confused.  Particularly that I get E4+1. 

Funny you should mention that, I always have issues with my E4, More 4, and ITV4! BF says he has it happen all the time at his house too.
No idea how to fix it, I've tried retuning and it didn't fix it.  Mine never seems to work during and after rain, wind, fog, snow, etc (so like all the time!)

Put the tv back where it was and see if that helps. When I have fuzzy reception I can just shift my box and usually clears it up, you'll just have to shift the entire set.

Don't be confused by the fact that E4 and E4+1 are related stations.  As Hendy pointed out, they are carried on separate multiplexes, so as far as technical aspects are concerned they might just as well be BBC and ITV or any other two stations.

Digital TV is broadcast using six mutiplexes.  Each multiplex carries multiple stations (hence the name, obviously) and occupies the space that one conventional analog TV channel uses.   The six different multiplexes are labeled 1, 2, A, B, C, and D.   If you look at the list of which stations are on each multiplex, you'll see that all of your affected stations are on MUX 2, while E4+1 is carried on MUX C:

Around Bristol you are most likely on the Mendip transmitter, which transmits these multiplexes on the following channels: MUX 1 = Ch. 59;  MUX 2 = Ch. 55; MUX A = Ch. 62; MUX B = Ch. 65; MUX C = Ch. 56; MUX D = Ch. 67. 

Certain antenna and cable problems can result in the signal in one part of the band being affected while other channels are still coming in strong.  So in the case of Mendip, if you had a fault which was severely attenuating the signal on channel 55, it would affect any and all the stations which are carried on MUX 2, which is what you are experiencing.  (You might be on a local relay which will use different channels for each multiplex, but the principle is the same.)

Unless your local transmitter is running that particular multiplex on reduced power temporarily for some reason, you are almost certainly looking at a problem with your antenna or the feeder cable.  It could be that the aerial has moved a little, or that damp has gotten into the connection block, or you have a damaged connection at the plug, etc. 

If you find that moving the set and cable around to different places affects the signal drastically, this is a classic indication that you have a bad connection somewhere.

Thanks folks!  I'm going to move the set around and see what happpens.

I just haven't bothered to try to fix it yet.

Finally!  Yay!  Spot on Paul.

I had just been unplugging and replugging the aerial.  Just now I pulled the table that was in front of it back and looked closely at the way the plug fits into the receptacle.

In some positions is was out slightly.  While the aerial was detached from the set, I rotated the plug to get the best fit, rescanned my channels, and am back in business! 

Thanks everyone! 

 

I was having problems recently when I moved things around and although the cables were all connected still...a few of the channels vanished and some became pixalated in bad weather.  I bought a cheapy booster from Tesco that plugs into a power point socket and the ariels themselves and I got them all back again and the signal strength of all the channels went from 40% to 75%.
