alexei romanov: Although numerous viewers are experiencing problems with reception caused by the current spell of high pressure allowing transmissions from distant stations to interfere with signals from local stations, your on going problem with the reception of BBC HD channels is in my opinion, not necessarily associated with same.
Remote fault finding is totally dependant on feedback from the viewer with the problem, such as the result of any tests that may have been suggested, which in your particular case this is something which has not really been forthcoming, likewise unable to make a technical assessment of your installation.
By the way, I am particularly referring to the questions asked in my reply on Mon 30th May @ 5:05PM.

If you remove the booster there is not enough signal and as all the HD channels have disappeared anyway.We did get a leaflet about a year ago saying our TV signals may be affected by 4g for mobile phones.The booster filters this and is variable and set about 4db.The television is a 32 inch Samsung HD about two years old and is on permanent stand by as not a single switch on it,operates by remote only,can't see the back to get actual number.

We still need a full post code to stand any real chance of helping rosolve your reception problems. Without that it is not possible to give targetted advice.

LindaB: PA7 5HD .Reception this evening is terrible for BBC,other channels fine.Never had these problems with analogue. In 1959 our TV worked with a loft aerial. Problems have been since they switched off the analogue and now have no choice.

Suddenly, this week, we have NO SIGNAL on CH 32. Other channels are fine so it can't be aerial positioning. What's going on at Black Hill?

alexei romanov: Thanks for the update, the content of having shed new light as to the possibility of other factors being involved which were hitherto unknown.
However, on the subject of 4g, were you contacted by a company called AT800? and if you were did they send you a 4g filter free of charge to fit in-line with your aerial?, as they always do with any household deemed as being liable to be affected by a newly installed 4g transmitter located nearby, as although your booster might well be one of the types containing an integral 4g filter, they are not nearly as effective as a proper stand alone device such as supplied by AT800.
On the subject of your TV's model number, although not being able to access same due to it being wall mounted is fully understandable, its still unfortunate that you cant, because some Samsung TV's in the age group mentioned were known to suffer from various problems including one connected with intermittent loss of audio on HD channels, you having mentioned this problem in one of your postings.
To be perfectly honest about it, I feel that the only way you are going to pinpoint the cause of your problem is by testing your aerial system using another Freeview device capable of HD reception, or alternatively your aerial system tested by an engineer equipped with a professional signal level meter.
By the way, undermentioned is a link to the company that supplies the 4g filters, if you haven't already been supplied with same? it would be prudent to give them a ring on their 0808 freephone number and ask if you are liable to be affected, (your post code will be requested) this company having up to date information on the exact location of new 4g transmitters.

alexei romanov: In addition to that said in my previous reply, I also meant to say that my reason for requesting a reception test with the booster out of the equation was purely to see if this restored reception of BBC HD channels "irrespective of any others having possibly gone downhill", as indeed previously requested by MikeP on May 24th @ 4.53PM.
Another point to could maybe clarify on concerns you having mentioned that you don't have enough signal without the booster, I take it that you are aware that this means by-passing the booster by removing the aerial connector from it and coupling same directly into the feed going to the TV? achieved by using either a standard coax female back to back coupler, or an "F" version of same if your booster uses screwed connectors.
The only reason bringing this up, being that some people are under the impression that switching off the power supply to the booster is all that's required, which of course it isn't!, as an unpowered booster acts like a high value attenuator.

There is simply no detectable signal on Channel 32 so boosting has absolutely no effect. Any ideas?
