Without knowledge of which transmitter you are near to nor the expected reception conditions, it is impossible to advise. Please provide a full posy code to this website so we can check those conditions.

Please provide a full post code so that we can see where you are in relation to the possible transmitters and what the expected reception conditions are likely to be.

Indoor aerials are never very reliable. I suggest having an expeternal wideband aerial fitted with suitable attenuation to limit the signal strength to below 85%. It should be aimed to avoid the worst of the possibl intereference from your local mobile masts.

Then your aerial is an old Group A type that was used for Crystal Palace but is no longer suitable. It needs to be replaced by a wideband type, prteferably a log-periodic. Call the Freeview Help line on 0808 100 0288 as you may qualify for a free replacement of your old aerial.

Bob Mudd:
According to Digital UK, you are almost on top of the transmitter - see Coverage Checker - Detailed View That is set to show reception expectations at your location. You should be getting excellent results for all three multiplexes.
Can you check what the signal strengths are for all three, please? The ideal levels are between 60% and 85%. Any less or any more is a problem (the output from the transmitter does not vary). If it is more, which is entirely poissible as you are so close, then you need to use an attentuator to reduce it to a level given above.
The other possibility is local interference.

There has been some engineering work done on that transmitter yesterday and tody. Retuning was a bad idea as you now have no idea of when the signal returns! I suggest a retune every hour until they do return.

The Government requires that to operate a TV receiver to watch 'live' programmes you must have a broadcast receiving licence. The Freeview and Freesat services are provided 'free' as there is no requirement to pay a subscription to watch via those systems - hence it is absolutely correct to call them Freeview and Freesat. Unlike watching via the Sky plartform where you have to pay a subscription to watch anything beyond the PSB services - and you still need the licence.

Bob Mudd:
The signal strength for each received multiplex is shown on the page used for manual tuning. Check in your User Manual for how to access that page. Once there DO NOT PERFORM A RETUNE, but merely look at the strength for each multiplex. The link I gave before shows the channels used for each multiplex. You need strength to be between 60% and 85% on every multiplex. Note we are talking about the strength and not quality.
Hope that helps?

Bob Mudd:
The signal strengths you report are way too low for any reasonable reception of anything. That's why you are having such problems.
First thing is to check ALL the aerial connections from the back of the TV right up to the aerial itself - but do be very careful if that involves access to the roof area.
A twenty year old aerial is likely to have serious corrosion problems, even though much of it will be aluminium - which is not corrosion proof! So I would suggest getting a good local aerial contractor to fit a new log-periodic or good wideband aerial and to replace all the old cables. Be careful not to fall for the 'hype' of a 'digital aerial' as there is no such thing (the aerial does not care how the RF signals are modulated, which is all that differes between analogue and digital services).

Hrdy and DJB:
In both your cases it could be that you have too much signal, as suggested by StevensOnln1. It is often the case that different equipment responds differently when fed too much signal. So I concur with the suggestion to reduce the signal strengths - it need to be between 60% and 85% for best results.
