This info is a bit out of date, any chance of updates please?
TruTV has gone.
Sony Crime Channel is on 60.
Also My5 will be replaced by 5Prime possibly today (13 Feb).
True Entertainment has appeared on 61 despite having strange signal problems bouncing up and down between 35% to 78% with picture breaking up a bit (every other channel is strong and stable). Any idea what is causing this? Is True Ent even supposed to be there?
Thank you

Paul: My5 has become 5Select (the originally announced change to 5Prime was dropped due to trademark issues, presumably with the Amazon Prime streaming service). If you are receiving True Entertainment then you are picking it up from a transmitter in England as it isn't present on any transmitters in Wales.

Mike: Have you checked for loose or damaged cables or connections behind your Humax box and TV? Please provide a full postcode so that we can see which transmitter you're using, where you are in relation to it and your predicted coverage etc.

kevin: Retuning will never fix a weak signal as all you are doing is deleting your channels which were already tuned correctly and searching for them again. Have you checked for any loose or damaged cables or connections behind your TV? The current hot weather conditions are causing TV and radio signals to travel much further than they normally would, resulting in interference from distant transmitters causing reception problems in various parts of the country which may be a factor.

I also live in Llandudno and have had the same interference and now loss of channels. I know of many others experiencing the exact same thing both here and in rhos on sea. It's obviously a transmitter problem which has got worse since some bright spark decided to carry out work during the busiest week of the town's year and whilst the world cup is on.

It is not due to the transmitter work but the weather. It is a well known natural phenomenon that occurs every year in warm weather and there is nothing anyone can do about it.
Patience is a virtue in these conditions.
