Hi Caz,
I think my issue is a little different to yours , i have all the channels but only some are effected by this interference issue mux 60 channels. If you have another TV ariel point you could try that if they run off the same Ariel or use a lony ariel lead and move it away from the wall to see if this improves it. I only know it is coming from next door as i have moved my tv away from the wall and the problem stops.
The easiest thing would be to try and move it away from the wall or pop round and ask. Have a look on the signal quality and strengh meter on the TV, you may have a weak signal.
Regards
Rob

rob: I HAVE FOUND THE ANSWER!!!!
Thanks for replying, my hubbie just told me that he's been turning off the booster thing in the sitting room every night and that is exactly when I lose the picture upstairs. We live on the very edge of the Oxfordshire area (Aylesbury) but still should get good signal.Apparently. When we had the new digital aerial fitted a few years back the guy also put in a booster thing where the aerial comes into the house behind the tv in the sitting room.It goes from there into the tv in that room. But when I found this out, I got him to test it, as like I said, he'd been turning it off every night coz the tv in there buzzes. When it is on, my digital channels upstairs are fab, when it's off, they pixilate and disappear!!! Try just getting a booster box thing, which just plugs into your main house aerial inlet? Do you live in an edgey area of the Oxford 'mast' too? Best wishes, Caz.x

Caz: Your blond husband is switching off the booster which is likely to be located adjacent to the aerial. What is referred to as a "booster" is in fact a power supply for a booster which is fitted where the single feed from the aerial splits into two, one to each room. Thus, by turning off the power supply the booster has no power and a booster with no power will give out little or no signal.

Well, good news for you, mine is definitely interference from next door. Does anyone have any ideas on how i can protect against it?
Regards
Rob.

rob: I just have to ask have you had the aerial checked out. I have never heared of interfereance from the next house. If your coax is damaged this could be letting in the interfereance but a good aerial with good coax with sheliding should block it. So call someone out to check what the problem is this website is good for advice but without being at your house no one can give you 100% the answer.

Rob: I'm in Oxfordshire and I had on and off reception with some channels last few weeks too and this week lost a lot of channels including the HD channels. Surely this is just down to the oxford transmitter engineering works this week? That would be why your neighbour also has poor reception. It was obviously not a great signal before which I assume is why they are working on it. Is there any way of finding out the details of the engineering work? (51.6887,-1.2717)

Because of Rob's very different location to you, the suggestion of a 'booster' (better called an aerial amplifier) is not correct. He is only 7 km away from the Oxford transmitter so gets a good strong signal already and it does not need amplifying. If it were then in his location he would have had far worse loss of services because of the signal then being far too strong.
As we do not have any idea of your location, other than it being in Buckinghamshire (with is not a small county), we cannot make any suggestions.
As David Linsay has stated, the item behind your TV set that is connected in the aerial feed cable is a power supply, the amplifier is mounted close to your aerial. The power supply needs to be left powered on to operate the aerial amplifier so your bedroom signals are properly delivered.

Much earlier in the discussion of Rob's problem it was established that it is only affecting one TV connected to his system in the room that is adjacent to the wall which has his neighbours Virgin equipment at the other side. The problem is not present on his other TV sets, so the aerial is fine and not a factor in this particular problem. Likewise, he has tried moving the TV set to the other side of the room successfully, again showing the aerial system is not a culprit.

Thanks Mike P,
Hope the neighbors ring virgin for an engineer like they said they would. I cant see this being anything else than em interference, hoping that the engineer will move the offending source.
could by a new tv but don't really want too and there is no guarantee that the new one wont do the same.
regards
Rob

Rob: Have you as yet tried turning your TV around by 90 degrees so as to have it facing end on to the offending wall? the reason for this request being that I suspect that your TV "might" be more susceptible to picking up locally generated EM interference directly into its PCB circuitry if any of the internal earth bonding jumpers used to link the metal screening cans on such as the tuners or any other vulnerable areas have not been tightened up properly, or indeed are missing! and should anything of that nature apply then any interference being picked up in that way is usually highly directional whereby is affected by angles, likewise turning the set around by 90 degrees or so being one way one way of revealing its existence without having the benefit of any test gear being to hand, that being your biggest impediment!
