The symbol shows the location of the Bluebell Hill (Medway, England) transmitter which serves 200,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Bluebell Hill (Medway, England) mast?

Thank you for the response Dave,

Unfortunately using manual tune doesn't give me a signal strength.

Actually scanning using manual lists 22 sevices on C46, none of which are available to be stored.

Checking the signal using the TalkTalk box I get 60% strength and 100% quality on BBC 1.

I can't remember the last time I tried to use the TV tuner, but a few months ago it was OK.

Can't understand why both freeview boxes are getting all the channels, but the inbuilt one in the TV isn't.

Thanks,

Steve

Steve: Can I ask how the TV and the box are connected. The Talk Talk (ok, really a HUmax) manual would probably tell you to put the main feed into the back of the recorder, and then get another aerial lead and 'loop through' into the TV.

If thats how its been done, then you know that your aerial feed is at least working (although more on that in a moment). If its passing fine via the box (and if it wasn't, you'd get nothing at all via the TV), then its worth just changing the aerial lead from the box into the TV. It could well be very loose, damaged, etc, hence the very dodgy signal.

There is one thing which might point to something else, or a combination of a dodgy aerial lead and something else. Your predicted signal from Bluebell Hill should be good, your just 9km from it! In fact a Talk Talk box would normally be screaming from too much signal. Now if you've put an attentuator on the feed that makes sense, but 60% is not that high for a transmitter so close with a tuner known to be fairly sensitive. It could be that your main aerial is fine for the Humax/Talk Talk, but the TV tuner is less sensitive, and perhaps compounded by a dodgy aerial lead, your getting very limited signal into the TV. You try swaping the main feed directly into the TV, just to see if that helps.

However, I'd check your main aerial as well as change the extra aerial lead, because your problem might be further up the chain.

Steve : In addition to that already said (by others). You stated on your initial posting that - no amount of re-tuning made any difference, but though did you try resetting the TV?, e.g: by carrying out a "manufacturers reset" / "default setting" / "first time installation" or some similar meaning name, as resetting is "sometimes" the only way of rectifying odd problems.

OK, the main aerial goes into the back of an old freeview boc with a loopt through gizmo, then into the TalkTalk box, then to the TV.

I have ordered 2 new coax extensions, WF100 cable, which I assume is going to be a lot better than the stuff I have at the moment.

I will find out how to do a manufacturer's reset on the TV and try that also.

The coax from the aerial is good quality, but I must admit to having the aerial in the attic as there is direct line of sight, so that's probably why the strength is so low.

Thanks again for all the help.

Steve: Yout loft TV should be fine with direct line of sight - your only 9km away! In fact you night get away with an indoor aerial at that distance.
OK - so the signal goes via an old Freeview box (if the TV has a Freeview tuner, take it out of the circuit -you dont need it), then into the Talk Talk, and then into the TV.

The better cables might help, but do some tests first.

a) Put the feed from the wall directly into the TV and see what you get. If the signal strength is suddenly really high, then you know that the problem is somewhere along the chain (and again, if something doesn't need to be there any more, take it out). And check the aerial cables. The ones you've just ordered will be much better, but you can certainly get duff cables. In fact I was wiring up the 'new to us' TV last night, and one coax cable was shot, which took a while to work out, since it was looping through.

B) Make sure the TV is tuned to the right transmitter - it happens!

c)If the TV is getting a rubbish signal after all that, then it might be the tuner (make/model?), but I suspect the problem might be nearer the aerial, perhaps a dodgy connection in the roof or something. At least its in the roof, so you can check it more easily than if its on the roof. If the tuner is shot, then you have at least a backup with the Freeview box you've already got (and simply dont bother connecting up the TV tuner at all), plus the Talk Talk. But the extra tuner is really handy, since you can watch one channel and record two thers all at the same time.

Well, thanks for the all the help.

I am sure I tried the aerial straight into the TV before and got the same result.

Anyway, first I completed the factory reset, still no good.

Aerial straight into TV, now got all channels, hurrah.

Back to going through the old freeview, and TalkTalk boxes, no BBC.

Using a spare coax cable tried all combinations of cables, still no BBC.

Checked aerial into TV again, all OK.

Left out old freeview box, no BBC.

Put old freeview box back in, left out TalkTalk box, all OK.

So it was the new TalkTalk box, went into settings, sure enough the loop through was "off", switched to "on" and all channels now available on the TV.

Now, I would have thought the TalkTalk guy seeing should have set this to "on".

But I also tried to use the TV whilst waiting for the new box and I couldn't get the channels, but by then I believe I had tried everything to get the old TalkTalk box working including factory resets etc. (had a lot of programs recorded), so probably turned off the the loop through during the process.

Again, thanks for all your help, and the new cables will probably be worth it anyway.

So back to being able to record four channels and watch one......

Steve

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
