Tim: Go into your TV's signal check screen and make sure that both the signal strength & quality levels are seen to be level pegging at about 75% or so, but if the quality is seen to be lagging to any extent then the dish is a fraction out of alignment, this most likely in the horizontal (left to right) plane.

If though the levels appear to be OK, then carry out a factory reset on the TV followed by a re-tune, this action will of course result in you losing any personal settings you may have carried out, like favourites etc.

Dennis: Carrying out the normal "Factory Reset" to wipe out everything stored in the memory will NOT delete your previously made recordings but WILL if "Format Hard Disc" is selected.

Have a look on the link, the section on the info you require about 3/4 of the way down the page.

John Chambers: And if I could just add, that purely with reference to the last part of your posting re; Friends living a mile away, in areas where reception from a lower powered mux channel is generally received on the weak side its not exactly uncommon for a person on one side of a road to struggle with reception whereas the signal is reasonably OK on the other side, as even a distance of only a few feet can sometimes show large differences in signal strength.

John Chambers: NOT that I am suggesting changing anything, as the low powered commercial channels and especially the one you are having problems with (ArqB 2.2Kw) all switch over to 100Kw operation on the date mentioned, something which will eliminate the majority of problems such as the type experienced by yourself.

David Brinkman: Just to exclude something, I would like you to go into the "manual" tuning menu screen on your G20 (and only on) and using the up/down arrows on the large centre button select Rowridges BBC on Ch24, if nothing is shown on the strength / quality bars then "slowly" proceed to pull the aerial plug out "whilst observing the screen", as I would like you to note if when the plug is just about clear of the socket (and no more!) if the strength / quality bars start indicating.

Matter of fact if you slightly offset the plug alignment with the socket so that its touching the socket off centre that's about the correct position for this test.

If though nothing changes, then reinsert the aerial plug and inch the channel up to Ch57 and see if Poole's BBC1 comes in, another channel to test being Mendips BBC on Ch61, giving an update on results.

You will probably already know this, but there is no need to scan anything on the Panasonic because as you inch up the channels it acts like a super sensitive signal sniffer, as the tuner is excellent on that model.

Although it has to be said that you must be in a somewhat better location for reception than the predictor would suggest if pre-DSO1 you were able to receive a reasonably good signal, as you are presently forecast as only being able to have variable reception from the high powered ("H" polarity) PSB muxes and nothing at all from the commercials, although Rowridges "V" polarity PSB's are indicated in the green.

Big Mart: As there are five mux channel changes and one disappearing you could just carry out an initial rescan with the aerial unplugged, then follow this with another rescan after reinserting same, but if any problems cropped up that lasted more than a couple of days I am afraid that its a reset job, as that would be inclined to indicate that some corrupted data is still lurking around in the tuners memory.

Angela: If I could just give another angle on this, as you are located at only 11 miles away from Crystal Palace then depending on the aerial system you use its possible that you could be receiving an excessively high level of signal from the high powered BBC transmitter, and which can in certain instances affect reception from the lower the powered transmitters, albeit this will all change on the 18th.

Just for a test, if you have a set top aerial lying around plug that in and carry out another re-tune.

By the way, it doesnt matter if a person misses a re-tune event as this is instantly corrected by any subsequent re-tune thats made.

Paul Jones: Sorry for the delayed reply but I failed to notice that you had given an update. However as far as your aerial is concerned, its possible that repositioning it would make a difference, but you should have a look at it to ensure that its facing towards Kilvey Hill which is on a bearing of 108 degrees from you, and importantly, that the aerial was mounted with its elements vertically polarised.

Another thing to try and see is if the end of the square horizontal bar that the elements are mounted on has a RED plastic stopper on its end, as that would indicate its in the correct group for that transmitter.

By the way, that booster you have although of an older variety is actually quite good.

Rod Craig: Yes, as if your Sony is actually 12 years old then its very unlikely that it has any chance of responding the the newer transmission modes that's being used now from when it was first manufactured, as some equipment half that age can have problems.

The other difficulty being that nothing can be done about the situation, as TV's are generally considered by the manufacturers as being obsolete over about 6 years or so old, although if you consider it still has a reasonably good picture then it would make a good monitor for a cheap Freeview box.

Rod Craig: Although still standing by what I have said re: age of TV etc, I just noticed that you haven't actually mentioned your location, (pref: post code or one from nearby) as this would enable the signal level expected at your location to be assessed just in case you are receiving an excessive level of signal, as no two sets handle this problem the same way.
