My freeview is giving me aggro, after moving from E6 3QY to DA1 2LP my previously reliable equipment has gone nuts, for example despite receiving 90 to 100 signal and quality from Crystal Palace the picture consistently breaks up, I found by manual tuning non Crystal palace numbers I can get it to work fine, however when it does its obligatory scan it says "new channels have been added" it then adds dozens more channels to the 800's and re tunes itself back to to crystal place and i have to manual tune AGAIN. it also regresses back to crystal place when it reckons the just added channels need removing because they are no longer transmitting and so it goes on. Is there a resolution for this frustrating behavior. i dont care what tv area i view, or is it just time to give up and look for a new box or tv.
I updated the firmware via the usb port but still crystal place breaks up and still cannot disable scan.
thanks for looking Anita

Anita: Should the aerial system installed at your new address use a booster then try by passing it, as what you have said could be an indication that your TV's or boxes tuner is reacting to receiving an over powerful signal and this possibility has to be eliminated before anything else is suggested.

Anita: In addition to that said, its also possible that your reception is being affected by the numerous trees that would appear to be located directly in line with the signal path, therefore it would be advisable to make a couple of enquiries with neighbours to determine if they are also experiencing similar difficulties to yourself.

jb38: Thanks for the suggestion. I will ask the neighbors this weekend and I presume the thing in the loft with the red light and the aerial type wires coming out of it is the booster. I will look into disabling that when I can borrow the ladder again.
Currently out of the four previously functioning pieces of equipment I have only a Pace HD box that works reliably and only if I select south east, this box doesn't seem to rescan back to crystal palace.
Thanks for looking Anita

Anita: Yes, its best that you make some local enquiries before doing anything "including" the booster bypass test, as its essential to have an idea of what to expect as far as reliability of reception is concerned as it saves you needlessly making checks that wont really prove anything.
The only reason I suggested the possibility of signal overloading is because of you having said that non Crystal Palace channel numbers work better, all of being received at a lower level, but having subsequently carried out a visual check of your locality signals other than from Crystal Palace might only be better simply because they are not being received via the trees referred to.
It would also assist if you could indicate the model number of your main TV or box being used, this to possibly enable its menu system to be checked out for the purpose of finding out if auto-channel update can be disabled thereby stopping it picking up channels from elsewhere, which according to the reception possibilities seen it can do.
By the way the box with the red light in the loft is most likely to be the booster/distribution amplifier.

jb38: Thanks for your time and suggestions Out at the moment cant remember main tv will post tomorrow, however I remember my daughters boxes they use in their bedrooms Sharp TU T2 which they use in conjunction with a old style tv and a flatscreen with a broken aerial socket (Bedrooms are the places where old tvs go to die LOL!) All you can do is choose between being notified or not.
Thanks for looking

To give the Sharp tut2 a little credit if you manual tune 40 you will ALWAYS have south tv BBC1 However if u Manual tune (i think)pick tv 39 (Strength 70) (Quality 80)u get perfect picture but without fail it ALWAYS reverts back to 22(Strength 80) (Quality changes over a few secs 100 90 zero) = no picture
This never happened at previous address
Thanks for looking

Anita: Yes, its rather ironical that by tuning to Bluebell Hill's 20Kw transmitter (C39) on you manage to obtain a good picture and yet the signal path from that station is indicated as being obstructed from 2.5 / 3 miles (although could be affected from 9 / see below), whereas reception from Crystal Palace (on 200Kw) and indicated with a clear line-of-sight is problematic, albeit of course that these indications are only with reference to the ground level and "not" anything on it, this including the dreaded trees!
However as far as your daughters TV is concerned, when you say "reverting back to C22" are you meaning because of it automatically updating channels? because if you do then go into the menu and under "Auto-Retune" select "Always Ask" then when it does at any time just cancel it.
If however you are not meaning the aforementioned then reset the box by reverting to using the "first time installation" procedure prior to manually tuning in the mux channels required.

Done some investigating this morning and think i have found the problem seems the aerial points at blueberrey hill. If signals don't like trees not sure pointing towards London would work it would be looking straight into trees etc defiantly no "clear line-of-sight"
