James Watt: Yes, as the RF modulators fitted into analogue VCR recorders of the real yesteryear variety were pre-set from the factory around C36, the only adjustment possible (although only in the 30's) being of a sweep nature via a screwdriver inserted into a small hole in the rear panel of the device. However in later devices where the modulators RF output channel was set up via the menu, C21 was (in my experience) the pre-set starting channel, the RF output channel being adjustable between 21 - 68.

Ed Henderson: Apart from the answer given by MikeP, the fact of you having mentioned Freesat as well as Freeview rather indicates that the problem referred to might be of a twofold nature, as Freesat is in no way connected with Freeview transmissions.

If by any chance you are connected into a communal aerial / dish system? then your problem is likely down to a defect in the distribution amplifier, the repair of same being the responsibility of the buildings maintenance department.

Debbie: Assistance can only be offered with problems of this nature if your location is known, this preferably being in the form of a post code or one from somewhere nearby, e.g: a shop / post office, this info then enabling access to details of the transmitter covering your area as well as the operational status of same.

Alan Herman: re latter query, its very unlikely that 4G transmissions (should this mode apply anyway!) are connected in any way with your problem as COM6 (C47) would also be affected.

You should try deleting everything stored in the tuners memory system by carrying out a retune on your TV / box "after" having first of all removed the aerial connection from same, reconnecting the aerial on completion followed by carrying a second retune to load the programme channels back into the memory.

Should this action fail to resolve the situation, if your TV / box offers a "manual" tuning facility, enter C44 (658.0Mhz) into the selection box but do "not" select search or scan, as in most devices if any signal is being received the strength / quality of same will be seen on the indicator bars.

Apart from the aforementioned, if you have any HDMI cables connected into the TV/ box, make sure that the aerial lead going into the set is kept well clear of same, as radiation from HDMI cables can cause problems with reception, the interference being of a frequency selective nature, i.e: knocking out one mux channel whilst having no effect on another.

Further assistance as required.

Ed Henderson: Many thanks for the update, really pleased to hear that the problem has now been speedily resolved thanks to your apartment blocks service management team, the nature of certainly not coming into the category of being time wasters!

Pleased to have been of assistance.

Gary Jones: Have you as yet checked if anyone else in your area is experiencing similar difficulties with reception? However stating that you reside in Newport is not sufficient info to enable access to the reception predictor, a facility which can also be used to assess the possibilities of reception from another transmitter, therefore a post code or one from somewhere nearby (e.g: shop/post office) is required.

Hilary: In addition to that said by MikeB. If the aerial outlet sockets in your six rooms are all connected into a powered distribution amplifier, which of course is the norm, then check that the power supply to same has not been accidentally switched off. If though it hasnt, then either the distribution amplifiers internal power unit has failed, or the problem is caused by a defect in your aerial system.

Kilroe: As no faults nor engineering work has been listed against Tacolneston, the problem "might" be down to a glitch having occurred in your TV / boxes tuner. If same has a manual tuning facility? try carrying out a manual scan on Mux C31 (554.0 Mhz) and see if this rectifies the situation.

Although a better method is to carry out an auto-tune "after" having first of all removed the aerial connection, this action blanking out everything stored in the tuner, reconnecting the aerial on completion followed by another auto-tune to load the programme channels back into the tuner.

Zimwemhanga : Al Jazeera (108) is now being carried on the COM7 HD multiplex, therefore this programme can now only be viewed on TV's or boxes fitted with full HD receivers, Freeview HD ready devices not coming into this category.

An easy way to find out if the receiver you are using is capable of HD reception or not is by selecting EPG 101 (BBC HD), if unable to view? then the device being used is not fitted with a DVB-T2 tuner, the type required for full HD reception.

Your location is indicated as having excellent reception from Sheffield's COM7 transmitter, the multiplex channel used by same being C31.

By the way, if you are able to view BBC HD (EPG101)? try carrying out a retune "after" having removed the aerial connection, this action blanking out everything stored in the tuner, reconnecting the aerial on completion of the aforementioned followed by carrying out a second retune to load the programmes back into the tuner.

I find your statement of having previously viewed Al Jazerra and other HD channels a bit puzzling, as Al Jazeera wasn't an HD channel prior to having been moved.

Kevin W: Your TV / boxes EPG listings might require updating, therefore carry out a reset on your TV / box followed by a normal auto-tune, this on some Freesat devices referred to as "first time installation", you having to enter your post code into the box in order to receive news services appropriate to the area you reside in.
