PaulN: As far as the old transformer is concerned its not really worthwhile replacing the thermal fuse anyway as its not really known for sure what caused it to fail in the first place, as although its not exactly unknown for a T/ fuse to fail as simply "one of those things" and with replacement of same bringing the amp back into life, but though on the other hand the overheating "might" have been due to the transformers primary having developed a partial short across a few of the windings thereby over-volting the remainder and causing excessive current to be drawn, and so if the fuse had simply been replaced you might possibly have found that the problem re-occurred after an hour or so when the transformer reached the point where the heat once again resulted in the fuse to failing.

debra: Judging by what you have said would suggest that your problem is possibly being caused by either a faulty connection where the coax joins into the aerial or that water has entered same, or alternatively that the aerial itself has been moved out of alignment by the wind.
You should also check that your booster box hasn't failed by observing if switching its power supply off makes any difference to what you can view, although a more accurate test is to temporarily bypass the booster by connecting the aerial directly into the TV's aerial socket.
As far as your neighbours aerial is concerned, provided its used for that said then it can safely be eliminated as being in any way connected with your problem.
By the way, any queries involving reception should always be accompanied by a post code or alternatively one from nearby, e.g: a shop / Post Office etc, as its impossible to check details of the transmitter covering the area without same.

Heyder: Now that its known you are using an A240D booster / splitter then testing the magic eye out in the loft could pose a bit of a problem for you, insomuch that the magic eye's input (from the RF2) is via a female coax connector whereas the cable in the loft from the Sky boxes RF2 socket will be a male "F" connector to match the A240D's input, meaning that you would have to use a female "F" to male coax adaptor, this type of adaptor generally not being readily obtainable from the average TV shop.
However, although this would undeniably have been an ideal test by the fact of it being halfway along the cable run, but when taking the aforementioned into consideration then its maybe best that you try the other test suggested, being to connect the uplink from RF2 straight into downlink that feeds the kitchen magic eye, as although this would still require an adaptor (female "F" back to back) for joining the two male "F" connectors together these "are" readily available from most places that sell "F" connectors for under £1.00.
Another point being, that I did note you had said that the system was working OK prior to the problem having developed, and so there is always the possibility that the problem is actually with the circuitry associated with the "sensitivity" of the boxes IR return as magic eyes can be notoriously troublesome on some installations, but the only way you could verify if this should apply or not in your case would be by trying another Sky box on your system as any type of Sky box would do for the test.

Kath : Although as MikeB has said your best bet would be to purchase a twin tuner Freeview PVR such as the Humax suggested by same, it is however possible to make recordings from your TV's scart 2 socket if connected into the Liteon as AV2 has an output facility.
That said, you are obviously limited to recording the programme you are viewing, and if the TV is placed into standby the output facility is liable to fail as it all depends on the internal circuitry associated with the socket.

mary: There are a number of things that can be responsible for your problem, however its not really possible for anyone to assist with queries of this nature without having knowledge of your location, this in the form of a post code or one from nearby. e.g: a shop / post office etc, as this would then enable details of the transmitter covering your area to be checked out.
The other point being, are you on a communal aerial system?

Mandy: If the flat has twin input feeds from the dish then provided the dish has been operational when the previous occupier moved out then the Sky box should work exactly the same as it was in your old residence.
As far as the TV is concerned, it will of course also work exactly as before if coupled into the Sky box, but however not on any other mode such as Freeview unless the flat is fitted with a normal aerial connection.

Margaret : If you are definitely referring to" Freesat" (satellite) and NOT Freeview via a normal aerial then no or bad signal in most cases is always caused by the dish either being out of alignment or by water having entered the "F" connector on the dishes LNB.
Purely out of curiosity, what is the model number of the box you are using? and are you connected into a communal dish system?

Margaret: The great point about satellite equipment is that any problems with reception is always associated with some aspect concerned with the reception side of the equation.
An LNB does not work like an aerial by the fact that with satellite reception the box (Humax in your case) sends control signals to the LNB for the purpose of band changing / polarity switching, and if any defect occurs in this system its reflected by missing programme channels.
Now the equipment you are using is known try swapping the two LNB inputs over, the reason for this test being that LNB1 is the main input used for normal reception and if anything is amiss with the port / cable on the LNB being used for that input then the situation will change by reversing the inputs over.
Should it subsequently be found that the situation has not changed then its either the case that the dish is slightly out of alignment or the actual box has developed a fault, that is provided that whatever radio channels you might be referring to are actually still being broadcast!
By the way, if you are viewing a BBC or ITV channel and you press the " i " button on your remote control what levels are being indicated on the strength bars at the bottom of the screen?

Margaret : Just a small addition to clarify on that said about band switching.
When you are selecting a programme to view on a satellite receiver every channel you select instructs the LNB to switch to a particular combination of low band or high band operation combined with either a vertical or horizontal polarity, these changes being achieved by the box sending two different voltages plus either a 22Khz tone or not dependant on the channel selected.
If for example water has entered the LNB's "F" connector then this will cause a short circuit to the 22 Khz tone necessary for high band operation, meaning that although the channel may have been selected on the box the LNB will not have responded which results in a "no signal" message.

Sandra : In addition to that said earlier on, should you be using Freesat (dish system) and are unable to find EPG 112 in the programme guide then your EPG menu requires updating, this simply achieved by carrying out a complete retune on your box.
