James Feest: You will have to carry out a "first time installation" on both sets as Dave is now on (12) and with Drama on (20) although Yesterday still uses (19), and so if after having carried out the aforementioned you find that its still missing can you receive ITV4 (24)? as that is on the same as Yesterday.

By the way "first time installation" is also known as "factory reset" or "default setting" or similar dependant on the brand of equipment.

The other point being, that if you use for then work has been taking place there since 27th and you might have retuned whilst the transmitters had been reduced.

BRIAN

Hopefully your issue was down to works.

As HD are on UHF 21 and are on other UHF settings then it is possible to have an issue with some and not others. channels are transmitted on 6 different UHF settings, if one setting is not being received correctly then all channels on that setting will have issues.

However, if the problem continues you should check weather you have a group A or aerial.

Group A are designed to perform well on UHF 21-37

Widebands are designed to perform on UHF 21-68 however they only perform well the higher up the UHF spectrum you go, due to this they do not perform very well on UHF 21 which is the channel you HD channels are received on.

Jamie. Thanks for the response, further info today, all hd started playing up this afternoon, on the menu it is the that drops from 10 to 0 then back up to 10. I coupled my old sony hd tv to the same an ran them in tandam, whenever the pana lost its hd signal the sony was steady as a rock, does that mean it is more likely the new panaisonic tv?

or could it be the below as it mentions CH21, if so why would it effect the pana and not the sony?

4G at (at800) issues
Tests now show that SOME households AND are in poor signal areas AND that are very close to a 4G phone MAY have their Freeview service disturbed: : ArqA, : BBCB

brian: When I looked at your first post earlier today, my first thought is that your strength is too high, and although your Sony seems fine, signal strength is still probably the most likely problem.

When the strength gets too much for the tuner, the first to go are the HD ones. Strangely, different brands react in different ways. Panasonic is known to be very sensitive, whereas Sony (although actually quite sensitive) is less likely to break up. My Sony PVR has a current signal strength of about 85% - and it got to 93% before it began to break up.

If you have a , try bypassing it, and see:https://ukfree.tv/fullstory.php?storyid=1107051892

Thanks Mike, bit of a noob when it comes to tv stuff, as i said strength is at max the same as the signal , however it is the signal quality that shuts down from max to zero and not the signal strength, not sure if that would be caused by the signal strength being to strong....the article you refer me to says to get the highest quality on the signal you can.
So it could be 1) signal strength, 2) 4g problem or 3) faulty tv, which did work fine for 4 days.....thanks for the assistance mike and jamie

brian: If the is up and down like a yoyo, but strength is 100%, its too strong a signal. Its certainly not 4G, and the TV is probably fine - as Mazbar said, if you have a problem with a TV, it tends to be a big one.

Follow the advice in the article and thats one less problem, and enjoy the telly, including the online stuff and your snazzy voice remote!
