Gail: Try connecting your magic eye directly into the Sky boxes RF2 socket and see if it lights or not, if it still fails to light then either the eye is defective or its the Sky box.
But though, its best to check that the RF2 socket on the Sky box is still powered, the procedure for checking being to press "services - 4 then 0-1-select" and this will take you into the installers menu, select and press on RF outlet.
You should also check that the batteries in the remote control are OK.

Excitymouse: Motors TV is broadcast on the COM7 HD transmitter which operates on a much lower power than the main channels, your problem most likely being caused by the signal received from this transmitter being low to the extent that its not much above the minimum required to resolve a picture, but with it dipping under at times hence why you are unable to view the channel.
By the way, this multiplex is also used by (107) BBC News HD / (109) Community HD, likewise its assumed that when Motors TV drops out you are also unable to view these programmes either?
Further advice can only be given if your location is known, this in the form of a post code or one from nearby, e.g: a shop / Post Office, as this would enable access to info on the transmitter that covers your area.

Excitymouse: I can certainly see what you mean by very close! indications being that you are located at only 2.1 miles away from the transmitter, although a signal path check using the terrain indicator does not really show your location as being in the shadow of a hill, although obviously you will know whether you are or not by being resident in the area. Can you see the mast?
As Caradon Hills PSB transmitters are radiating on 100Kw and with the commercials being on 50Kw, under normal circumstances any receiver located at only a couple of miles away could easily suffer from overload problems, and as such an aerial installer "might" possibly have incorporated an attenuator in line with the aerial to take the edge off the signal, the point being, that if one has been fitted in your aerials down lead? the dB rating of the device might be a tad high and is partially killing the signal from COM7, this transmitter only radiating on 11.57KW.
Try carrying out a signal strength / quality check on BBC1HD (Mux C22) making a note of the levels seen, then (if motors has not returned) go into the TV's tuning menu and select "manual tune" followed by entering Mux C31(COM7) into the box but do "not" press search or scan, as on most receivers if any signal exists the level of will appear on the signal bar.
Further advice dependant on the outcome of this test.

Excitymouse : My reply was based on what you had said in your posting @ 08.46PM, being unaware that you had followed this up @ 09.01PM, but now having read that said in your 09.01PM update, should you be able to receive 107 & 109 but not 71 indicates that your TV or boxes EPG requires updating, this achieved by removing the TV or boxes aerial connector then carrying out an auto tune to blank out everything stored in the tuners memory, reconnecting the aerial on completion followed by carrying out a second auto-tune to reload the channels.

Dave Lindsay: Yes, thanks for the confirmation of that seen on Megalithia, as I was unable to use Google Earth some unknown reason earlier on, albeit that it seems to be OK now.

viv : If all three TV receivers are definitely being used on Freesat ? (via a dish) and with each of the individual coax cables from them being connected into their respective ports on the dishes LNB, as satellite equipment "cannot" share a connection such as can be done on Freeview (via normal aerial), then your problem has to caused by something having happened to the coax feeds from the LNB that runs to each of the two secondary boxes.
You should temporarily try each of your boxes (if that's what you are using) on the satellite connection used by your main TV in order to ensure that they are still fully operational, or alternatively if your large TV does not have Freesat built in and is being used in conjunction with a Freesat box? try this box on each of the coax feeds used by your two secondary Freesat devices.
Further advice dependant on feedback.

quentin: Have you as yet, verified if anyone else in your area is also suffering from the problem referred to with regards to a mass of horizontal rectangles afflicting reception in both mornings and evenings, something which comes into the category of being rather odd, as although anything of an alien RF nature clashing with a digital TV signal generally results in the break up of the picture, its not in the fashion of a clearly defined pattern such as you have mentioned.
On the subject of replacing the cable, although modern satellite grade cable is in most cases superior to coax made in the era you have referred to, but as far as killing off interference from France or any other European station is concerned, virtually nothing you (or anyone) can do will alleviate the problem, as viewers located in large swathes of the Southern areas of the UK can suffer from this at various times of the year due to reasons similar to what you have mentioned, although its usually at its worst during warmer weather.

John Sturdy: If your system is genuinely operating on an outside dish then the box connected into it must be a Freesat device and not Freeview, as the latter uses a normal aerial system.
What I find a bit puzzling is how you manage to connect the coax from a satellite dish into a Freeview box or TV, as the connectors used for satellite devices have whats known as "F" connectors which screw into a threaded male socket.
Maybe you could clarify with regards to the model numbers of the devices being used.

Michael: Although that said by MikeB is quite correct for the dates referred to, but be aware of possible interruptions to the service occurring at any time during this week starting today, as engineering work is being carried out at the Sandy transmitter.

mark688: Does the situation regarding the signals on the ports change if you swap the boxes LNB1 & 2 inputs over? The other point being, that if the two ports you refer to are on a Sky+ box then the signal levels on the check screen should never vanish no matter what channel you choose, as these level indications only represent the default transponder.
Further advice dependant on the outcome of the above mentioned test.
