martyh: Well, anyone who is intending to purchase a new TV and is thinking along the lines of a Panasonic brand set cannot in my opinion, really go far wrong no-matter what model in the range is being considered, including of course the two mentioned by yourself, as Panasonic is one of the few brands that I take no hesitation in unreservedly recommending to anyone that is after a reliable TV capable of giving excellent performance "once its been set up", this meaning after the picture settings having been adjusted for personal taste from that of their default settings, and in particular the three modes usually seen at the bottom of the selection list, namely: Vivid colour - S.A.T.S - P-NR, and with these being changed to OFF before adjusting the brilliance / contrast etc.
I do have to say though that as an engineer I am inclined to look at these sets more from the technical side of the equation as far as their internals are concerned and also their performance as an actual TV for the purpose of displaying a high quality picture that is received via an aerial, or in the case of a Freesat model including a dish , and my recommendation of these models concerns only their RF performance and picture quality aspects rather than what they are capable of achieving / facilities obtainable when connected to a modem.
However as far as reception is concerned, these models are also fitted with top class tuners that are capable of performing well over a wide range of signal conditions, the only minor criticism that I do have of them being that they tend to give a slightly embroidered indication of the levels received when compared to a proper signal meter, of course most sets are inaccurate in this respect and with the only device I know that isn't being the tuners used in a Humax Freeview box, top class!

Hi - I have no issues with other channels, but suddenly have poor reception on ITV. It flicks between poor and no signal through to normal viewing. I've tried retuning.
Can someone help please? I only had the arial put in 3 months ago...

panasonic as JB says is about the best with Sony where tuners are concerned
LG and samsung are good but only in a top class set up near to a transmitter otherwise you get the odd picture glitch every few minutes

Sasha: If it is only ITV that gives problems check that the ITV you have stored on button 3 is the correct one for the transmitter that the aerial is pointing to. Check on the signal strength screen for signal strength and quality plus the UHF channel/frequency that is being received. How does this compare with say C4? Also look in the 800s of the channel list for any alternative ITV that works correctly.

NICK ADSL UK: Yes spot on! as the problem with LG and Samsung tuners is that they do not have a very good signal level tolerance range, whereby on one hand they require a reasonably good signal level to produce a glitch free picture whereas on the other hand they cannot cope with situations where even slight signal overload conditions exist, likewise will block reception well before any of the two devices I mentioned show any signs of problems.

Hi Jb38. Would you care to give your opinion on the link that follows, under the heading: '4G to affect TV reception in two million homes'? BBC News - 4G to affect TV reception in two million homes (BBC News Website). Regards, martyh.

martyh: Well I look at this potential problem in various ways, and putting aside my sense of outrage that something has actually been sanctioned that is already known (or suspected) beforehand as having the potential to affect a mode of reception (Freeview) that by its very nature is already vulnerable to being interfered with by a number of things, including of course nature. (inversion effect etc)
That said, I feel that this issue is being somewhat over hyped to a certain extent by a number of well placed non-technical types (in the practical sense) but with the means to be extremely vocal, and this is causing many people to panic quite unnecessarily about this issue, although I do admittedly feel that anyone within a couple of hundred yards or so from one of these masts could well experience problems "if" the Freeview signal they receive is sitting at a lower than ideal level for reception, this automatically making the receivers tuner more vulnerable to interference from any RF sources nearby.
The whole thing is really a wait and see game, because when dealing with RF signals other than microwaves its quite impossible for anyone to accurately predict exactly what will happen as so many variables exist with peoples installations, coupled to the fact that its notoriously difficult to predict exactly what level of interference (if any) that viewers will suffer from if they reside anywhere near to a mast, as RF predictions, whether for reception or expected levels of interference, are up to a point educated guesswork unless on site tests are carried out.

martyh: On reading over my reply I feel that I should clarify part of a statement made, insomuch when I referred to non-technical types with the means to be extremely vocal, I was mainly meaning media types who consider themselves to be an authority on technical matters.

Crystal Palace - answering my own question and asking another.
I replaced all internal cabling and fitted a new distribution amp and have restored my missing channels.
However although I now have good signals on BBC-A, D3+4 and BBC-B I don't get any signal at all from SDN, ArqA or ArqB multiplexes from Crystal Palace.
Digital UK tradeview does not show these channels as being available but they are listed here as being broadcast from CP at the same power as the other multiplexes. Why can't I receive them from CP? I can get them from Hannington but they are at a lower level and I am on the outer edge for good reception from there.
