Ian: If your CCTV system is of the type that sends the image picked up by the camera to the TV via its aerial input socket? then this signal is from the control units "analogue" RF modulator, therefore in order to view the signal on your TV you will have to set the TV's "input select" button (on remote control) to "analogue", followed by carrying out a scan to pick up the signal sent out by the control units modulator, which its assumed is on C50 on your device, that is unless the analogue modulator offers the choice of more than one output channel.
Many CCTV devices do to avoid the possibly of the signal clashing with a channel used for Freeview reception, although C50 is OK in your particular case "if" you are receiving Freeview from Blackhill.
However, if on the other hand your CCTV device is of the "movement sensor" variety that couples into your TV via a scart lead connected into the TV's AV1 input? then that said with regards to analogue does not apply, in other words you do not require to alter anything on the TV, because as soon as movement is detected the control unit sends a signal (via scart lead) into the TV that switches it over to the CCTV device no matter what programme you happen to be viewing.

G,newcomb: Although engineering work is presently undergoing at the Pontop Pike transmitter, any periods of reduced power found to be necessary are usually only of an intermittent short term nature of possibly up to an hour or so, and although the effects of reduced power may not actually be noticed by viewers who reside in a good signal strength area, it can however cause problems to viewers located in less than ideal areas for reception, which judging by what you have mentioned "might" possibly be applicable to your location.
Although unable to assess if its liable to or not without a location being known, this preferably being in the form of a post code or one from nearby, such as a shop / post office.
That said based on you "not" having carried out a rescan on finding a blank screen, because if you have? all this action achieves is to delete everything stored in your TV or boxes tuner, frequent rescans then being necessary in order to reload the channels back into the tuner.
If by any chance you havent carried out a rescan and yet the channels are still missing, it would be prudent to check with someone nearby to ascertain if they are also suffering from similar problems with reception, the purpose of the check being to eliminate the problem being associated with your installation.

D Mutter: If your are meaning that programme channels normally viewed are now indicating no channel when selected, then carry out a reset / retune on your TV or box to update the programme guide, as changes were recently made to some of the the EPG listing numbers.
If though on the other hand you are referring to additional HD channels broadcast on COM7 and COM8 multiplexes, then Dover is not one of the stations allocated to provide extended HD services.

Gary Briggs: Indications suggest that you are receiving Freeview from the Hemel Hempstead Town transmitter located at just over 1 mile away, no faults being listed against the transmitter nor is any engineering work taking place at the station, therefore although you have tried a few measures to overcome the problem such as trying a new booster, your best policy would be to ascertain if the problem is actually associated with your installation or not by checking with some other household in the area to find out if they are also suffering from similar problems with reception.
My reason for suggesting this being two fold, the first being the fact of the signal path from the low powered (8 watts) transmitter being obstructed by dense vegetation in the Felden Lane area, secondly that there is also the possibility of 4G being involved, as the frequencies used by H / Town transmitter are in the range potentially most affected by any 4G transmission tests possibly being conducted in the area.

Grant: With regards to the aerial being placed next to the window, does the window referred to face towards the Clevedon Road railway bridge (@ 81 degrees) where the transmitter is located?
The point that has to be appreciated being, that the Kelvindale transmitter only rated at 2 watts output with its transmission being vertically polarised, and even although its located at only 0.6 miles away from you it cannot be taken as a foregone conclusion that you will receive a workable signal from it under your particular circumstances.
You should try a test by going into the tuning menu on your TV or box, selecting "manual" tune" followed by entering C52 (Kelvindales BBC) into the box but "not" followed by pressing search or scan!, because on most devices if any signal is being received the level / quality of will appear on the indicator bars no matter how low the signal might be.
If nothing is being indicated? leave this menu on the screen and move the aerial around to see if there are any traces of a signal, as this procedure causes the tuner to act like a form of signal meter devoid of threshold cut off levels.

J: P/code indications would suggest that you are connected into a communal aerial system, if you are? then you should check with someone else who resides in the block to find out if they are also experiencing problems with reception, as a fault could have developed on the distribution amplifier system.
The other point to remember being, that as you have already tried retuning your TV or box and not received any signal, then the retuning action when no signal is present will have deleted all channels stored in your TV or boxes tuner, frequent retunes now being required to recover same otherwise you will be unaware when/if the fault has been rectified.
That said being on the basis of you having checked the jumper lead coupling your tv into the wall plate outlet socket, and that you are on a communal aerial system.

Grant : Small correction to that said regarding the location of your local transmitter, it is of course Dalsholm Road railway bridge (next to the recycling centre) and not Clevedon Road.
The other point I ommited to mention being to try the test twice, one with the gain control fully advanced, and the other with it set at minimum.

John Dunmall: When you cancel your Sky subscription your viewing card automatically reverts to being a normal viewing card of the type referred to, as all Sky does is to disable (via OA download) the access code which enables you to view the channels associated with the package you happen to be subscribed to.
You can of course view a range of channels on a Sky box without the card even being inserted into the box, as all the card really does (when no subscription is involved) is to allocate the news services etc appropriate to the area you reside in, otherwise the box defaults to London.
However, you will lose the recording and playback side of your box by cancelling your subscription, plus you will be restriced as far as viewing HD channels are concerned, as you will be limited to BBC HD channels / ITV1HD / Ch4 HD but not anything of a +1 nature.
But though on the subject of recording, Sky was offering ex-subscription customers the chance of retaining the recording / playback side of their box if they took out a new subscription "purely for this purpose" at the time of cancelling their package, the cost being around £10.00 or so per month, although to my knowledge, most viewers decided against going down this route and opted to purchase a Freesat twin tuner recorder which is 100% compatible with Sky dish systems.
By the way, you can easily find out what you will, or will not be able to view once you cancel your subscription by removing your card then running through the channels normally viewed.

wayne: Stating that the TV "is tuned in correctly" is inclined to suggest that you are recording from the TV into your recorder?, if you are, then did you remember to set the video recorders "input" selector to the socket used on the recorder to connect it into the TV? And of course "not" placed the TV in standby unless its known that recordings can still be made whilst its in the standby mode.
By the way, according to the programme guide on my recorder True Entertainment starts at 06.00 every day, with The Waltons being on at this time next Saturday and Sunday.

margaret: The Dalry area is indicated as being served by either the Darvell or Blackhill transmitters, the latter providing a better signal as far as the commercial channels are concerned.
However, as the TV in the second room would apparently receive all the channels OK, this then indicates that the signal is actually there, but is possibly being received at a level under that necessary to resolve a picture on your main TV, as tuner sensitivities vary from set to set.
Therefore, if your main TV is not wall mounted? you should try temporarily connecting it into the outlet socket used by the TV in the other room followed by carrying out a retune, if this results in the restoration of all channels? then the next stage is to reinstall the TV into its original location followed by checking that the channels normally viewed are still there.
Should they be OK? then this is inclined to suggest that your system could benefit from the addition of a powered amplifier / splitter to feed a higher level of signal into your two aerial outlet points.
However, before carrying out any of the aforementioned procedures, you should try carrying out a manufacturers reset on your TV or box, this procedure also known as "default setting" or "first time installation".
