Jb38 I did try manual scan as well, as suggested, but no signal shown. Good signal strength shown for mix channels that it was tuning though. Bizarre that same aerial socket/leads picks up all channels via other freeview tuners but that toshiba 19" suddenly stopped doing so after working perfectly and still won't work after new PCB fitted. Planning on getting Samsung replacement.

Cannot receive any mud via indoor aerial that I have. Not aware that signal booster being used. Have rooftop aerial that is distributed around house via distribution box in loft. Not easy to get tv into loft to connect up directly so not planning on trying that. As all other freeview boxes working with same aerial/signal feed it does seem to be problem, of unknown cause, that has developed in the Toshiba. Thanks for suggestions so far.

MH: Best policy! although just from my own interest point of view the first chance I get I intend to have a look at the service sheet to see if the tuner is part of the main PC board, which of course is quite common on smaller TV's, because only a defective tuner can cause your problem as far as the fault being within the TV is concerned.

The other aspect being that possibly the tuner isn't available as a spare part as yet and this is why the entire board was changed.

Although one final test I would like you to try is to connect the offending TV straight onto the aerial and not via any splitter that you might be using to feed your other boxes / TV's, re-tuning it of course after having connected it directly into the main aerial.

Very difficult to get access to aerial directly in lift as no boards etc and I do not want to risk damaging tv before returning it for replacement. Many thanks for your assistance to date.

Happy ending. Just collected my new replacement TV, Samsung, for problem Toshiba. Samsung tuned in to ALL available channels first time with no pixelation/breakup etc. do not think that I will be buying Toshiba again.

MH: Good news then!! and pleased to hear that all is OK now thanks to your new and superior replacement, the success of on tuning same somewhat proving that the Toshiba's tuner was the proverbial duffer after all, as the tuner is the only component in the set (any set) that can cause that type of problem.

Thanks again for the update!

Hi. Help. We seem to be having the same problem as MH was having at the end of September. We live in Aylesbury (HP19 postcode) and should pick up from the Beckley transmitter. Well, we did until last Thursday at 1645 when we lost all channels and no amount of First-Time Installation retuning will get them back. We have a Toshiba 22BL702 22" widescreen Full HD 1080p Backlit TV with Freeview (to give it its full title) which we bought on May 23rd 2012 and worked fine until last Thursday. Is the fact that we cannot pick up a signal likely to be with the TV tuner? Nothing has changed with the set-up so I'm a bit stumped. And I missed the Liverpol match last Thursday (not that it was the result I wanted...). Thanks for any help or advice you can give.

Hello, Simon J Bolton.
Can you try your TV on a different aerial? Can you try a different TV on your aerial?

Hi Paull. Thanks, but we've tried both (sorry, should have mentioned that in my first posting) and still get nothing. We tried the (roof)aerial of our neighbour but the TV still does pick up any channels. We know the aerials (next door and ours) are ok and we know the transmitter is ok, so I think our next step is just to return the TV for repair/exchange. Mind you, the way Liverpool are playing at the moment there's no rush...
I'll post an update when I have one.

Simon J Bolton: Although it does appear as though your Toshiba TV's tuner has failed you should try a manual tune test, this done by going into the installation menu and selecting "manual search", then select "digital" by using the <-> (left/right arrows) followed by selecting "channel" and once again using <-> to obtain the channel required (Ch53 BBC) followed by pressing OK to start search.

If no results are obtained try the same test again but using Ch62(ITV3 etc) if still nothing is found then this would suggest that the tuner is defective.

By the way, all that's been said is on the assumption that no booster is being used on the aerial system, as if it is then it must be by-passed for the test just in case your signal is excessively high, as that can likewise result in nothing being received because of tuner blocking.
