christy m: If the dish with wires on it was operational when the last tenant left then it should still work when you connected your box to it, as "no signal" could be caused by a bad connection to your box (maybe "F" plug, short circuit) or that the LNB on the dish is faulty, or the dish is out of alignment, even the possibility that the last tenant was using it for continental TV reception on 19.2 degrees.

MikeH: According to the trade predictor, Ch56 is not showing as being receivable on IP12 post code areas until the 20th of this month when the channel number changes to 41 at switchover stage 2.
Even then only the first three Mux's are shown as having good reception, these being Ch44-Ch41-Ch47, the latter being the HD Mux, the remaining three being classed as variable until June 2012, although MuxD (Ch63) does improve slightly on 16th of November this year.

Sue B: If you received the channels OK up until a couple of weeks ago, then there is a possibility that the reason for not doing so now is maybe caused by transmitter upgrading work, this being where your post code is essential for verifying purposes as well as looking at what is possible in your area.
Quite a number of people in various areas of the country have experienced similar situations to yourself during upgrading work, but once again a post code is essential to check on this possibility.
The fact that your TV works with the aerial coupled directly into it just simply means that you are on the verges of receiving a working signal and no more, anything placed in line with the aerial reducing the level hence the picture glitches or vanishes.
If however none of the possibilities mentioned apply, then an aerial amplifier mounted as near to the aerial as possible will definitely help the situation.

David: Just purely out of curiosity, what model number of Panasonic Freesat TV are you referring to?
Regarding what Mark has said, most retailers are not really technical people and as such haven't a clue about system specifications, with "trading standards" being the people you should take your complaint to, that said though, even they have to seek technical advice when dealing with any complaints of a nature such as yours, so instant answers are never forthcoming.

MikeH: If I could just add what I omitted to mention on my original posting, insomuch that a "signal" level of 36% is not usually sufficient to resolve a picture on most digital equipment, this no matter what the transmission mode might be, albeit that what Dale has mentioned would apply to any equipment that wasn't capable of operating on 8K irrespective of how strong the signal might be. (or not!)
Dales post code location (IP2) indicates variable reception on Ch's 56/68, whereas your post code indicates no reception being possible, this because anything received will be under the so called "digital cliff", an effect that I think you are experiencing.

David: Thanks for the info, and as probably realised the reason for asking being that I wanted to have a look at the manual to "check the spec" so to say, as it so happens its virtually identical to the later "G20" ranges with the tuner being DVD-S2 capable and the symbol rate being shown as having a maximum of 30MS/s.
It seems to be the 23k symbol rate that is causing the problem, or more accurately the lack of being able to choose it, as I was worried about this on my own G20 model as it didn't appear as being a manual choice, however a subsequent auto-scan gave the desired results, this being suggestive that a mysterious (and lengthy!) download I noticed the set carrying out much earlier on in the year "may" have been connected to adding the 23K facility to the sets reception capabilities, as I couldn't determine any other reason for it.
By the way, the TV doing an automatic shutdown reboot on completion of the download, this rather fascinating other members of the family who happened to be watching at the time.
Indications seen in the tuning menu after the reboot whilst viewing BBC1 HD.
S/R : 23000
DVB : DVB.S2
Modulation : QPSK
FEC : 8/9.

Sean: Reception capabilities can very quite considerably between different brands of equipment dependant on design of their tuners, so this alone can cause one set to pick up something that another wont.
The other factor is that of the aerial feed arrangements to the various sets, if a daisy chaining (loop in/ out) method is used the set at the end of the chain will receive less signal, hence it might not operate correctly, but if the aerial goes into a powered splitter then that guarantees that each set will have the same signal, so if one device falters on that system its nearly always because that device itself is less sensitive than the others.

Sue B: Your post code indicates that you should be getting good reception across the board from either the Mendip or Wenvoe transmitters, especially Mendip albeit this only by a small factor on Mux's A-C-D, with the reception not forecast as changing even after the final upgrading is finished in 2013.
A way to check what station you are receiving from being, go into the sets tuning menu / signal check area whilst on BBC1, if you see Ch61 showing its Mendip, whereas if its Ch41 its Wenvoe.
All that being said though, its generally better NOT to be receiving TV signals across water, as depending on circumstances fluctuations of the signal can occur, and so in theory Mendip is the preferable signal.
To clarify your situation maybe you could come back regarding the BBC1 channel you are receiving the signal from.

chris: The answer totally depends on where you are located and what your aerial set up might be, with neither being mentioned!
Ch24 being the high powered PSB2 Mux on the Sandy (Anglia) transmitter.

GIna: Error code 29 just really means that the box is not seeing the default transponder.
To rectify the problem start by taking its power lead out and waiting about 15 secs before re-inserting it again, then wait for about another 20 secs or so to let it initialise before pressing the Sky button, once done let it go through its usual "searching for listings" procedure.
If however it doesn't respond to that then that could possibly indicate that the dish has moved slightly out of alignment, or that the box itself has developed a fault.
