Mike Broadbridge:
You are just 7 km from the transmitter so are likely to be getting a very strong signal, perhaps too strong. So start by checking the indicated signal strengths on all the multiplexes. They need to be between 60% and 85%, any more will cause significant problems that can be cured by fitting an attenutator into the aerial cable behind the set, using a new flylead to prevent the weight from 'hanging' on the aerial input socket.
You should also check that you are tuned to the correct channels. Put your full post code and house number into the Digital UK Coverage Checker at Digital UK - Coverage checker and scroll down to find the Sudbury transmitter details in the listing. That will give you all the current, and future, channel numbers being used for the multiplexes.

Possibly all just a coincidence but ...
1. My freeview tv suddenly stopped working with "no signal" (two weeks ago)
2. Next door neighbour has just had a new arial because was getting interference
3. House over the road has had some arial work done.
I have sent my tv away for repair (still under guarantee) I am waiting to see what happens.
Postcode IP11 9LP (North Felixstowe)
Have there been aany changes to the transmissions? (Sudbury I think)

Rob: There are no changes reported for Sudbury in the last couple of weeks, although reception of some multiplexes aren't predicted to be the best at your location. Did you check for any loose or damaged cables or connections before sending your TV away, or did you just assume it was at fault?

The last engineering work carried out at the Sudbury transmitter was on 1st August 2018, no other work has been done since.
It is worth checking your aerial system to ensure that all the cabling is in good condition and that all joints are in good order. If there are coaxial plugs/sockets then unplug those and refit them to clear any possible corrosion/oxidation from the contact surfaces.
If you have access to another Freeview TV then use that to check that your aerial system is working correctly.

Ipswich can get interference from continental tv stations but if the problem is recent I suspect a problem with your aerial or its connections or plugs. (possibly a source of interference such as a new phone mast may be the culprit. But your aerial system being faulty is more likely .)
Your area is a bit complicated for best reception. See the digital coverage checker as Mike suggests. You could get rock solid basic BBC and ITV channels with a small possibly loft aerial (vertical polarisation) from the Ipswich relay transmitter . the other channels probably need a good outdoor aerial for Sudbury . Idealy one with low pick up to the east (rejects continental signals ) A few channels (that you might want ) are better from dover . But having two or three aerials is probably for experimenters and enthusiasts !

There are currently no changes for Sudbury next year. It's changes at other transmitters (which is why you'd need to look through DigitalUK) that will affect reception of signals from Sudbury at certain locations in Sudbury's reception area.

Thanks for all your responses. I have now had the TV back from the repairers. I don't know if they actually did anything, but it worked fine for a few days and now (18.30 on Wed 24th Oct) it has suddenly started (intermittently) doing the same. I have a high gain external arial and a 4 way booster/splitter in my loft. The other TVs in my house are working fine and I have tried switching them around. It seems that perhaps this particular TV has a weak RF/tuner stage?

Please can you check what the signal strength is as repoirted by that TV set. You can usually find that on the manual tuning option - but do not retune.
Some sets have rather sensitive tuners that do not respond well to too strong a signal, so the usual advice is to aim for no more than 85% strengths on all the multiplexes. Other makes may have a less sensitive tuner so are less affected by too much signal.

Rob . because you can receive several transmitters it might be that particular tv could have trouble selecting the right frequency for a given channel. Maybe not so likely with a modern tv . But to check I would use the tuning menu to verify that the set is tuned to the correct UHF channels (not freeview channels).

I agree with Mike that too much signal for a sensitive set is a possibility . Perhaps one way to temporarily test on a lower signal is to connect the aerial without the amplifier.
