Which companies have run the Channel 3 services in the Llanddona transmitter area
I live most of the year at LL54 5RS. and have recently purchased a LG oled smart TV. We have a hightail aerial pointing towards Llandonna transmitter on Anglesey. We borrowed a Panasonic TV to test the reception before we decided to have a TV in our home. The Panasonic was able to receive BBC HD BBC 2 HD and all ITV HD channels.
The LG channel search will not find Channels 101, 102 etc and nothing between 100 to 201??
I have either not got a setting right on the TV or those channels are not available from the Llandonna transmitter. I am 75 and just venturing into the world of a television . Please help. Cofion Mel

Mel Nevitt: Your postcode is predicted to have good reception from Llanddona which is only 22km away. You should certainly be able to receive BBC One HD, BBC Two HD, ITV HD, Channel 4 HD & Channel 5 HD on 101-105 as these channels are broadcast from every transmitter. Try going in to the manual tuning option on the TV's menu and do a scan of UHF channel 46.

I live in Dwygyfylchi and experience regular issues of interference of multiple TV channels
Probably about 2 or 3 times per month I have issues with all BBC channels but never all channels at the same time. The latest issues are today 18/12/21

I assume you mean the BBC SD channels today (18/12) or does that include the HD ones as well?
When exactly was the previous occasion?
I can't find any faults listed for the transmitter and it's not been listed for Planned Engineering since the end of October. Most parts of your area should have very good reception from Llanddonna but without a full postcode the predicted reception in your locale can't be confirmed, it's possible you may be in an awkward spot!
It's possible that your problem today is weather related.
There is currently some moderate to strong temperature inversion/tropospheric ducting conditions affecting large parts of the UK and these weather conditions can disrupt reception for brief or longer periods. The conditions are predicted to last on and off for a few days.
The BBC currently have a warning in place.
That said there are a number of things worth checking.
Is your aerial external or loft mounted? How old is it (roughly)? Do you have a distribution amp/splitter?
Have you changed anything in your set up since this first started?
I would check that your aerial seems intact and pointing in the correct direction and that your downlead looks undamaged (especially if it is old) and not flapping in the wind if external. Also check all your coax plugs, connections, flyleads etc, behind the TV, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them.
If you ever retuned at anytime when you had no signal, that's never recommended as it usually just clears the correct tuning or you may end up tuned to weak signals from another transmitter.
Check in your TV's Tuning Section that you are tuned to the correct UHF channels for Llanddonna. These are C40, C43, C46, C41, C44, C47 in the order PSB1/BBCA, PSB2/D3&4, PSB3/BBCB HD, SDN/COM4, ArqA/COM5, ArqB/COM6
To be clear, the Main BBC SD Channels would be on multiplex BBCA UHF channel C40.
Check that you don't have any trees that have grown high that are on the line of sight to the transmitter (or very very close by) or things like scaffolding or new buildings.
See what signal strengths and quality you are getting for the multiplexes (groups of channels) shown in your TV's tuning section, that information may indicate issues with your aerial or downlead or possibly any distribution amp/splitter you may have.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.
Make sure you don't have any HDMI leads near unscreened/poorly screened flyleads/aerial leads as HDMI has been known to cause interference.

The transmitter hasn't had any current or recent reported faults and isn't currently listed for Planned Engineering.
You don't mention whether your upstairs TV has a separate aerial.
If it's the same aerial as the downstairs TV, does that have a signal?
Has the signal returned now to the Upstairs TV?
If so, it was probably the weather conditions at the time.
There has been some Temperature Inversion/Tropospheric Ducting which has been disrupting signals in various parts of the UK for some.
Essentially it results in interfering signals from other transmitters in the UK or Europe reaching you and so your wanted signals are disrupted. It won't necessarily affect all multiplexes or necessarily at the same time if more than one. It can last for seconds, minutes, sometimes hours or longer.
Despite the incorrect spelling, this link does work - simple technical explanation
It's always possible these conditions may affect you again during the next 24hrs according to some current predictions.
If you continue to have problems, post back with more detail about your aerial installation(s), any distribution amp/splitter etc.
