Tracy: Provided that you are not intending to record anything then use the lead that goes into the LNB2 input as both LNB1 and LNB2 are technically identical to each other.
If part of the LNB1's "F" connector broke off then these are easily obtainable from most electrical stores for around 75p or so, the connectors simply being screwed off (anti clockwise from end view) the coax and with the reverse procedure being used to fit the new same..

Chris : Although its neither here nor there now that you are thinking about making changes to your set up, but on the subject of your present equipment, although your Toshiba recorder could indeed have developed a fault, but though on the other hand the partial post code supplied could indicate that you might be located as close as 9 miles (or even less) away from the Sandy transmitter whereby "if" you are using a roof mounted aerial, especially if boosted in any way, then the signal received could be a little too strong for the Toshiba's tuner hence the erratic reception.
Humax devices in general being far more able to cope with this sort of situation hence don't suffer from signal overload problems in the same way as many other TV's and boxes do.

DaveW: As the WFAV25 is a 10 - 25dB variable gain device is the problem still evident when the amp is set on its lowest setting?
It would also have been of assistance if a post code had been supplied, as this would then have enabled access to the reception predictor / info on the transmitters covering your area.

Linda: As you are located at just under 12 miles away from the Hannington transmitter and with a clear line-of-sight to the station (excluding man made structures / trees etc) then in theory anyway, you should be able to have good reception.
Have you as yet checked with anyone else residing nearby to determine if they are also experiencing similar problems on the same programme channels? although I fully appreciate that many prefer "not" to have to do this, in some cases with good reason! but its essential to know if the problem is only confined to your installation or not.
However if they aren't, then carry out a signal strength / quality level check on one of the problem channels, paying particular attention for any erratic variations being seen in the quality level of the signal.
Further advice dependant on reply.

james andrews: If you are referring to the Corris Freeview PSB only station then no faults have been reported concerning this transmitter.
However, according to the reception predictor your location is outwith the coverage area of this transmitter., although if you were previously receiving from this transmitter your signal has possibly dropped under the reception threshold to resolve a picture.
Therefore to test if it has, go into your TV or boxes tuning menu / manual tune and enter C45 (BBC) but do NOT press search or scan, because if any signal is being received (nomatter how low) the level of should appear on the signal strength / quality bars.

dave simpson: Indications are that you have a clear line-of-sight with the Keelylang Hill transmitter @ 22 miles / 359° although Rumster Forrest operating on lower mux channel numbers can also be "partially" received and which "might" have been stored in your TV or box, therefore you can check whether they have or not by carrying out a signal strength test on each of the following EPG's (programme number listings) for the purpose of cross checking the transmitter mux channel number seen along with the strength / quality indications, e.g: EPG 10 being mux channel 42.
EPG programme number test : 1 (BBC1) - 3 (ITV1) - 10 (ITV3) - 11 (Pick TV) 18 (4Music) plus any HD channel.
Keelylang Hill muxes: 46 (BBC) - 43 (ITV1) - 40 (HD service) - 42 (ITV3 etc) - 45 (Pick TV) - 39 (4Music)
If your TV or box does not indicate the mux transmitter channel number along with the signal strength indications then carry out a factory reset (or first time installation) followed by manually tuning each of the mux channels one at a time, storing same if not automatically done!

dave simpson: By the way as far as the aerial is concerned, its not so much a case of changing it for a better model but making sure that its positioned as far away from the source of interference as possible, this also applies to the powered booster / splitter.

john: Re: latter question, most likely yes! although you can easily find out if this is the case or not by selecting a programme channel thats working OK and looking at the signal strength / quality its being received at, because if both strength and quality indications are indicating 60+% then in most cases the dish is OK although its always preferable for the quality to be leading the strength, if however its lagging then that generally indicates that the dish requires a slight right to left (or vice versa) trim as its slightly out of alignment.

Chris: It would also have been of assistance as far as the signal level expected at your location is concerned if your posting had included a post code, as the level of the signal being received determines whether or not its advisable to purchase a powered splitter rather than the passive type referred to.
You can of course get a rough idea of whether the signal level received is high enough or not by checking the undermentioned Freeview programme guide number channels one at a time via the Humax, noting if any glitches are seen.
EPG channels referred to being: 1 (BBC1) - 3 (ITV1) - 10 (ITV3) - 11 (Pick TV) - 18 (4 Music)
You then bring the Toshiba into the equation by removing the aerial from the Humax and connecting it directly into the Toshiba's aerial input socket, a coax jumper lead being connected from the Toshiba's aerial out socket being connected into the Humax's aerial input, do NOT alter the scart connection between the Humax and the TV as this test does not require any connections to be made on the Toshiba other than its aerial in / out.
Power up the Toshiba to ensure that the loop through is working then carry out the EPG channel number check on the Humax in exactly the same way as was previously done, once again observing for evidence of any glitches that may have cropped up since the previous test, if none are observed then the signal level being received at your location is of a sufficiently high enough level not to cause any problems.
By the way, what is the model number of the Humax in question?
