Alexei Romanov:
Yes it can be caused by too much signal! That's why we contributors ask people to tell us what the reported signal strength is on the multiplexes they are having problems with.
Please check the actual strengths reported by your TV set and give make/model of same please. Note that we are asking for strength readings and not quality figures.
In you case, I conjecture that you may have too much gain in your amplifier. Too much signal is not a good thing, it was not good in the 'old' analogue TV days and is even worse for digital signals, expecially the HD ones.
We await your strength figures, etc.

alexei romanov : Irrespective of any other advice given, as these intermittent problems with reception stretch back to around August last year, one thing I haven't seen mentioned as yet is if they are also being experienced by others in your "immediate" vicinity, i.e: neighbours?, as knowing whether they are or not would at least allow the elimination of one of the two possible causes of said problem, that of (1) a deficiency in your
installation, or (2) due to external factors remote to your household, likewise beyond your control.
My reason for enquiring is basically due to the fact that although you are indicated as having a clear line-of-sight with the Blackhill transmitter its only just and no more, as the terrain (ground only) signal path indicator (Megalithia) shows the signal skimming over a high spot of land at approx 1.5 miles prior to your location, the area in question roughly coinciding with two ranges of trees located to the East side of the M8 motorway, the first (and worst from the TX) being on either side of the old Greenock road a tad to the North of the high voltage overhead line distribution depot.
Reception in situations such as described can on occasions (usually weather / atmospheric dependant) have an element of the erratic involved, trees having a dastardly effect on the data carried by RF signals, this resulting in some muxes being affected whereas others aren't, although any that are usually suffer from quality related issues and not necessarily strength, which in many cases can remain high.
Therefore, the next time you see a weak or no signal warning on BBC HD, go into your TV's tuning menu and select "manual tune" followed by entering C40 / 626.0 MHz into the channel box but "not" followed by pressing search or scan, as in most Freeview devices if any signal is being received, nomatter how low it might be, the strength and quality of the signal will appear on the indicator bars.
However, that said is on the assumption that if any HDMI type cables are being used in your installation to connect your TV into other devices or vice-versa, that said cables are "not " running close to the aerial lead, as the radiation emitted from some HDMI cables can be of a frequency selective nature, i.e: affecting some Mux numbers and not others.
Further advice dependant on reply.

jb38: Most of the neighbours are on cable or satellite. The set only gives signal quality and I use shielded OFC cables.At present all channels are fine.I don't watch a lot of television, mostly listening to Dab radio which can sometimes go as well.

alexei romanov: If the problem referred to is still in existence? try removing the aerial connection then reinserting same "whilst you are viewing the screen", the purpose of being to see if the picture flashes on the screen then off again the instant you remove the aerial connection.
If though it doesn't, then try switching the TV or box off for 10 seconds or so before switching it back on again, checking if this action has resolved the problem. If any of the two procedures have? then this is inclined to point to a deficiency in your TV or boxes software.
By the way, as you have mentioned that your Freeview device does not have individual strength and quality indications, it would be of assistance to know the model number of the device in question.

jb38: I have now found signal strength(Support, self diagnosis ) 68,and bit error can be as high as 200 on BBC1HD.The signals just went again on HD channels.

alexei romanov : If you have now found how to access your Freeview receivers support menu and are able to view the BER level, 200 being a measure of the data corruption on the signal received which on a good installation is zero, however, BER indications (quality in non technical terms) are always accompanied by signal strength, should this now be the case, what level is it indicated as being?
I also noticed in your reply to MikeP (May 23rd / 7.11pm) you had said that you need to use the booster to watch anything, if you are now able to view signal strength on its own? I would like you to try a test by leaving your Freeview device on BBCHD, noting the signal strength / BER level then see what happens by removing the booster from the equation.
The reason for this being, that receiving a signal that's a tad too strong for a tuners front end will nearly always result in false level readings being obtained, i.e: strength usually indicating much lower than it actually is but always accompanied by a high bit error rate (BER).
I would also be interested to know the dB level indicated on your booster, that is in addition to the model number of your Freeview receiver, as this enables specifications to be checked.

jb38 The signals have gone again on BBC and also HD channels.STV and other channels are fine though I don't want to watch them.BBC signal strength was down from 68 to 48 and bit error 2000.

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.
