Gweneh: If your aerial is facing Aldeburgh ( @ 6 miles / 162 degrees) then it will be mounted with the elements facing up and down, whereas for Tacolneston (@ 25 miles / 314 degrees) it will be positioned horizontally, and if indeed it is facing Aldeburgh then its a bit surprising that you are picking anything up from Tacolneston with the aerial being so far out of alignment, because even if it wasn't the only mux that's indicated as providing a good signal is COM4 / SDN (ITV3 etc).
By the way, all of the aerials seen on the properties on the Middleton Moor main road are facing towards Aldeburgh, the only exception being on one of the three properties situated near to the pole carrying 4 electricity cables that run behind the houses.
Maybe you could give an update on the result of the aerial installers findings.

r. bedford: Well even if the batteries in the remote control are definitely OK? it could still be the coding side of the control that's defective even although it might still be able to switch the set on and off, does it?, but if you used to be able to change from ATV to DTV by pressing that button, which of course is its purpose!, then a fault has developed in either the control or the receivers IR pick up decoder.

r. bedford : On the subject of the apparent inability of the TV's "mode select" facility to respond to the button being pressed on the remote control, if the problem is NOT with the remote control or the TV's IR pick up / decoder circuitry, then it could be associated with a fault in the section of the power supply that's concerned with supplying power to the tuners switching system, if indeed not even the tuners themselves!
Unfortunately I dont have a service manual for that model, only its operating same, and with my first chance to access the manual not being until later on in the week, however irrespective of that the TV or remote is faulty and something that I now suspect has been the whole cause of your problem.
By the way, maybe you could confirm (or not) if the remote is able to switch the TV off and on?

Gweneh: If you could please! as I will be interested in the results.
By the way, thanks for the comprehensive signal report, all said has been duly noted for reference purposes.

Nicholas Willmott: Although it could be said by some that a Sky boxes RF modulator is basically an extremely low powered transmitter, it is however not a transmitter in legal terms but an RF generator in exactly the same way as found in a wide range signal generator used for testing receivers, and whose output (modulated or otherwise) can "only" be transferred to a receiver via a direct connection simply because that no point to point transmission via air exists, in other words its a closed signal transfer system that is incapable of transferring a signal via air of anything more than about 5-10 millimetres or so at the very most, sometimes not even that!
That said, no offence whatsoever is being committed by using a Sky boxes RF modulator no matter what channel its set to.
Of course, if someone connects the Sky boxes RF output into a small RF amplifier and then into such as a set top aerial to transmit the signal into another room, then that's a different matter!

r. bedford: It certainly seems to go from bad to worse with your reception!, however I would strongly advise you to ask for a quotation before any repair is carried out, because as said by MikeB replacement boards can come a bit pricey.

Ian from notts : If you are referring to the standard type of tunable RF modulators (and not a video sender) that covert the AV output from a scart socket into an modulated RF signal then no! they do "not" use different frequencies, as they operate on exactly the same frequencies / channels as a Sky box.
The three types I am referring to seen by opening the links.

David Ponsford: When the TV engineer fitted the aerial in the attic did he connect the coax you had installed into the aerial? that is the one than runs from the attic to behind the TV in the lounge.
Also, when he connected the cables into the rooms are these the cables you had installed from behind the lounge TV? if the answer is "yes" to both questions and the coax you used was of good quality then I cant quite see where the problem is, although the usual procedure is to have the powered splitter in the loft with a short coax from same going into the aerial, then with each of the splitters outputs being fed to wherever they are required.
On the face of it, all you have done is a variation on the aforementioned, insomuch by running the cable from the aerial down to the lounge and with it then being distributed from that point rather than the loft.
Further info on confirmation that what has been said applies, and that the coax used for the Sky box runs straight from the dish?

David Ponsford: In addition to that already said, if your coax wiring is configured as was previously mentioned then this system gives an element of flexibility over that if the splitter had been installed in the attic, insomuch that if you wish to use the Sky boxes RF modulator to feed the programme being viewed on the Sky box in the lounge to the bedroom TV's, (provided they have analogue tuners as well as DTV) then its a relatively easy process with the method you used.
The procedure being, you feed the connection from the aerial in the attic into the Sky boxes aerial input socket, you then connect a coax jumper lead from the Sky boxes RF1 output socket into the splitters aerial input socket, this then enables the signal from the aerial to pass though the Sky box and picking up the RF modulators analogue output in the process, both signals then passing though the splitter and onto the bedroom TV's, both TV's having previously been temporarily set on analogue and retuned whilst on this mode to enable the Sky boxes analogue signal to be picked up and stored, then reverted back again to DVB / DTV if the programme on Sky was not required in the bedrooms.

S J Chapman: On exactly what? a Sky or a Freesat box or are you referring to Freeview?
