jan: I suspected thats what you might have been meaning, the LNB inputs are the two connections from the dish on the rear of the box, just carefully unscrew them by only holding the nut type retainer (not the barrel) and swap them over, because if when you do this "no signal" is seen right away then the "ex" LNB2 input from the dish thats now connected into the LNB1 is faulty, and with the most likely reason being that water has entered the connector on the dishes LNB.
If this is found to apply then it requires the connector to be unscrewed from the LNB on the dish and then further unscrewed from the coax for purposes of drying out with a tissue, than after smearing the inside of the plug with some Vaseline the connector should be screwed back onto the cable again, but before doing so making sure that all strands of the braiding wire have been pulled back over the coax's outer cover, then finally screw the connector with cable back onto the LNB.
It should really then have a layer of self amalgamating tape wrapped around it for waterproofing purposes, although if the LNB is the type with a pull down shroud that partially covers the connectors it should be OK.

be: When you say that "nothing happens" are you meaning that when you press Sky it wont respond to the remote control? because if this is the case then have you tried a new set of batteries maybe borrowed from some other device that uses similar AA types.
If though you have done that and it still doesnt work then either the remote control is faulty (not a common fault) or its the boxes power supply that has developed a fault, this not exactly being an uncommon thing to happen on older boxes, and in particular boxes that are housed inside of a cabinet or ones that aren't having their side rows of ventilating grills blocked by the TV times and such likes sitting on top of them thereby causing overheating.

be: Irrespective of what may have been seen on Sky's website or heard from one of their customer advisers the average Sky box only requires to be left unpowered for about 30 seconds or so for purposes of re-setting, and when its plugged back in again it should start to respond to the remote control in about 15/20 seconds and finish its searching for listings procedure in about another 30 seconds or so, although this time can vary quite a bit dependant on the box being used with later boxes being a little faster.
As far as button No1 as well as the red one not working is concerned, thats more inclined to be caused by a worn key pad on the remote control rather than the box, you can check if the button is working or not if you have a digital camera, because if you point the control at the camera and press any button this will show up as a white dot on the cameras viewing screen, that said it only indicates that the infra-red sender is working.

maddy: You are one of many Sky viewers in Spain who have also experienced exactly the same problem since Ch5 was moved to the new Astra 2F satellite at the end of December, the reason for the problem being that the footprint (coverage area) of the 2F satellite favours the whole of the UK and Eire and with it even stretching into the Atlantic Ocean but with this being at the expense of Southern European countries, as the satellites footprint is seen to start tapering off around the Nantes level and with Bordeaux being considered as on the border line for reception, you being a considerable distance South of this.
Of course these footprints are by no means anywhere near to a 100% accurate indication of what's actually possible in a real life situation and reception can generally be achieved outside of the published range, albeit though only by using a really large 3M or more) dish! however I think that it would be somewhat stretching it for anything at all to be received as far South as you might possibly be located. (exact area not known)
That said, its possibly worth a chat to someone who resides more local to yourself and who is observed to be using a sizeable dish, as you cannot really beat a report from someone else in the same boat as yourself, as they say!

Gareth Jones: Well now that you have confirmed that you do indeed use a communal aerial system then this is something which somewhat limits the scope of what you can try, excepting of course the wire aerial test! but when taking this into account then about the only thing left that you can possibly do is to find out if any of your neighbours that you might be on good terms with happens to use a small TV in their bedroom that they would be willing to let you borrow for ten minutes or so for the purpose of trying it out on your apartments aerial points, you of course not requiring to do anything more than just plug it in and connect the aerial lead on to it, as the TV will already have all the channels pre-stored.
Should you be successful in managing to borrow a set then this would be an absolute boon as it would instantly point to the source of the problem, because if an engineer was called in to check out your system then the aerial points provided in the flat would be the very first thing that he / she (to be PC) would connect their signal strength meter onto, and if they were proven to be defective then it would save you a wasted visit to Richer sounds, because when dealing with communal aerial systems the possibly always exists that the coax line from the communal aerials distribution amplifier into your flat is defective, and there is no way of knowing whether it is or not except by testing it out using another receiver.
I should of course really have sussed out earlier on about the possibility of your aerial being communal, but by you having mentioned that it was on the roof somewhat swayed me into thinking it was yours.
Maybe you could give an update on how you get on, as I would be interested to know.

martyh: On having a look at the reception predictions for your area it would appear that where you reside could be problematic area for reception, as reception from Hannington (@ 22 miles) on all muxes (except presently HD) is indicated as being variable on a permanent basis, Crystal Palace (@ 30 miles) being reasonable on its PSB muxes but poor on everything else.
That said, reception predictors cannot be taken as being anywhere near to 100% accurate in what they indicate is possible (or not) and if you can presently receive the two Freeview PSB muxes (BBC & ITV) reasonably OK then the chances are good that you will likewise receive the same on HD.
Be careful when choosing a TV though just in case it does not have a DVB-T2 tuner as numerous people have been caught out by the way that these devices are advertised, any doubts whatsoever just post the model number on this site and it can possibly be checked out.

Lynn Steenson: On reading back through your various postings on the issue of zero quality being indicated on all of the COM channels, it would be interesting to know the outcome if you first of all blanked out all channels already stored in the TV's memory by carrying out an auto-tune with the aerial connection removed, checking the EPG list on completion of the scan to ensure that nothing is being indicated, then follow this by going into the TV's manual tune facility and entering Ch23 and check if the quality is still zero, if though it isn't then carry out a scan on this channel then when completed select ITV3 and check if a picture is showing.
By the way regarding your Echostar, if you scan channel 23 whilst its set on DVB-T2 than that will result in a zero indication, as the tuner will not recognise the signal.

JackMcKnight: Have you tried changing the RF channel that the modulator is set to? unable to advise on the best ones to use (and avoid!) without knowledge of your location, although I would use channels of around Ch64 upwards, not forgetting to retune your analogue TV's to find the new setting.

Dave Timm: Many thanks for your update on the situation as I was wondering how you would get on with the manual tuning tests, and with the basic reason for me requesting that you carry out this test being for the purpose of eliminating any possibility that your TV's tuner could be trying to store more channels than its memory capacity would allow, you actually having touched on this (maybe unwittingly!) when you wondered if hidden duplication could affect the EPG, which of course it can could do on any device with a limited channel storage capacity, this deficiency only being revealed when the device is switched off as it results in everything stored being lost.
However your single mux scan has proven that the "memory overload" issue is not applicable in your particular case otherwise Ch47 would not have been lost, and so this once again points to a tuner defect.
But though much as it might be a bit of a pain to carry this out but I would like to make one final request if you can still receive Belmont, the test being exactly as before insomuch blanking out everything stored followed by carrying out a manual tune but this time only on Belmont's channel Ch22 & Ch25, because I would like to know the subsequent outcome as far as the EPG is concerned when none of Emleys high powered channels are stored in the tuner, albeit of course that your tuner will still sense that they are there but hopefully with its auto-gain circuit not cutting back too much on its sensitivity.
One little point that I had previously meant to mention was, when the EPG vanishes does repeatedly pressing the guide button on the remote control have any effect?

Ruth: Meant also to say, that you could use the spare feed from the dish for a second Sky box located in another room or even use it for a Freesat box, because as far as dishes are concerned there is no difference between them.
