david: Just to add, what I mentioned was assuming that its Freeview you are referring to, if its Satellite then obviously the feeds to the boxes will be individual ones from the dishes Quad LNB.
Trying the box upstairs still applies though!

Mick Cartwright: Although I realise that you have dedicated your question to Briantist and so I don't really wish to intrude, however in the mean time if I could just confirm something you queried insomuch that Ch5+1 is EPG44 on a BT vision box and is received on the same SDN mux as is ITV3 (10) / Quest (38) and QVC (16) and a number of other programmes, these in your case received from the main station Winter Hill.
If you do not receive ITV3 etc, etc, either on your BT Vision box then it most likely has auto tuned to the PSB only station called Long Mountain which is shown as being possible to receive at your location, which of course being a PSB only station does not have commercial muxes such as SDN that Ch5+1 uses, hence you will not see them indicated.
I suspect that your main TV has also auto-tuned to Long Mountain and that's why you are seeing Ch5+1 slightly above the BBC up in the 850 ranges, as BBC1 / ITV1 etc from the Long Mountain will have taken up the low EPG channel numbers on your TV pushing Winter Hills channels like BBC1 / ITV1 etc up to the 800 ranges, the only difference being that Winter Hill also has commercial muxes containing SDN where Ch5+1 is located.
Although I am working from memory, but BT vision boxes are somewhat limited in their Freeview facilities and I don't think they have a manual tuning facility, and should this be the case (I will check later) it makes it extremely difficult in situations such as yours as you cannot use the usual trick of taking the aerial out whilst scanning then reinserting it at a given point, as Long Mountain and Winter Hill channels are interwoven.
Hope this helps to slightly clarify the situation.

kerry: Its quite impossible to say whether an indoor aerial would have any chance of working or not when you havent indicated your location, this preferably in the form of a post code as it would enable the signal strength expected in your area to be checked on.
The other point is, when you say "it has Freeview channels also" are you indicating that Freeview is received elsewhere in the house?

k: If the reception of every channel has failed its much more inclined to suggest that your aerial system has developed a fault, and so I would check the co-ax cabling as far as you can manage to.
There could of course be a fault with the TV's tuner, but that's not so likely a reason for your problem, cant you borrow a Freeview box for an aerial test?

kevin green: When you say "since the switch off" what switch off are you referring to?
The other point being, are you using a co-ax lead from the Sky boxes RF2 output to feed to the TV in the conservatory, that is if that's what you are doing? and if so have you tuned the TV in the conservatory into the RF channel used by the Sky box?
Finally, do you have an normal aerial connected directly into the Freeview box, or is it getting the signal via the co-ax from the Sky box? that is with the normal aerial connected into the Sky boxes aerial socket.
What you have mentioned can suggest various possibilities, and the points mentioned have to be known to be able to assist.

Michael: Although its always possible that the problem could be caused by the cable, however its much more likely that its occurring at the "F" connection to the LNB, so I would unscrew that and check that no water has crept in, then coat it with vaseline before screwing it back in again.

Penny: Well as you may already know a blue screen usually indicates that a TV is not receiving any signal, but you shouldn't really re-tune it as all you do is scrub what it has already stored.
What you should do though is check whatever you are using to distribute the signal to the three sets, if that appears as being OK then the other test you could try, albeit possibly inconvenient! and that is to swap the offending TV over with one used in another position, because if the problem moves location as well then you have the answer, its the TV that's faulty.

j: You cannot record from a scart socket on every brand of TV as it depends on the design of the set, if you had stated the model of TV involved this could have been checked on, however if you have the manual for it go into the specifications section / connections and look at the scart sockets description, and if you do not see "in / out" mentioned under the video heading then that's your problem.
If you dont have the maual then if you provide the model number this can be checked.

kevin green: Thanks for that update as it fully clarifies the situation now.
What you are doing is the standard procedure and perfectly correct, but you have to remember that when you are viewing the list of Freeview channels picked up by the box your TV will have switched off its internal analogue tuner over to the scart socket thereby blocking the Sky channels from being viewed, the easy way to correct the situation being to press the A/V button on the TV's remote control and that should enable it to revert back to its internal analogue tuner which is being used to pick up Sky's RF2.
The same thing should happen if the Freeview box is either placed in standby or switched off altogether, if you still cannot get the TV back on analogue pull the scart lead out, if that cures the problem then it indicates that either the scart lead is faulty or that the Freeview box is one of the odd types that hogs the scart link if connected to the mains.

david: Although you may well have tried all of the things mentioned it would appear by what you say that it was whilst the box is in its present position, so you should take it upstairs and try it in one of the standard boxes positions, as if it works up there then there has to be a problem with the downstairs aerial feed.
What arrangement are you using to feed the signal from the aerial three ways? as unless you have a really strong signal then it should be done via a 3/4 way powered splitter.
