Rob: I rather suspected that this might be the case! I will say though that most plastic cased digital equipment emits a certain level of noise that can be detected on an AM radio, although with this generally not at a high level after having passed though a properties double thick brick dividing wall, the noise referred to usually being of a purring / ripple nature especially from LCD TV's, the effect of being particularly noticeable at certain spots on an AM receivers MW band.
As far as the engineers visit to your neighbour is concerned, it would of course be advantageous to your case if you managed to be around when the engineer called at your neighbours house for the purpose of being able to give a demonstration of the problem.
The problem might even be caused by an iffy connection in the Virgin cable termination box, but with problems of this nature it could be anywhere in the system including the Virgin box itself.

mazbar: Although I would prefer NOT to be involved in any who said what debate, but on the subject of no-one having suggested switching off the suspect device, I had actually referred (28th @ 11.49pm) to the neighbour switching "everything" off as the only way of determining if his equipment was responsible or not for the problem.
And on the subject of the under floor cabling, I realise that its a bit time consuming to backtrack through all the postings made on this subject, but Rob had said on 25th @1.31pm that the fault was still evident even when the under floor section had been bypassed by using a fly lead from the wall socket straight into the TV.

jason knight: No, as a dish cannot be used for anything other than satellite TV reception.

jason knight: As a terrain check indicates your location as being line-of-sight to the Heathfied transmitter (trees or man made objects excluded) then an aerial such as a DM18 or standard DM log would be ideal for your situation, Heathfield being located at 12.5 miles / 350°.
However, if your living room window is North facing then you could try a reception test by connecting a short piece of wire (6 feet or so) into the boxes aerial socket and carrying out an auto tune, because should this result in a picture of sorts being obtained then this indicates that you are receiving a good signal.
You could of course use some of the less costly aerials around such as advertised by Argos, the Philex 14DW being ample for your requirements, the DM18 log being recommended for its more rugged construction capable of good performance, it being the shortened version of the standard DM Log.

However, before purchasing anything if your living room window is North facing then you could try a reception test check by connecting a short piece of wire (6 feet or so) into the boxes aerial socket followed by carrying out an auto tune, should this result in a picture of sorts being obtained then this indicates that you are receiving a good signal.
You could of course use some of the less costly aerials around such as advertised by Argos, the Philex 14DW (107 / 8471) being ample for your requirements, the DM Log basically being recommended as its a ruggedly constructed device capable of good performance.

By the way this is my 3rd attempt at replying the two preceding this one having vanished shortly after appearing on the list, please ignore should they spring up again!

Teresa: Meant also to say, make sure your secondary TV is set on "analogue" when you are carrying out the tuning procedure as the RF output of I.O. device is analogue and not digital.

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!
