To deal with the problem you must clear the channel list completely and then rescan - if your box has it in the menus, please the 'installation menu' to do an initial scan or a reset to factory settings or First Time Installation. You MUST delete the entire existing list of channels. On most boxes this technique can be also be used:
2) unplug the aerial from the Freeview box by disconnecting the cable from the 'RF in' socket;
3) wait 30 seconds;
4) plug Freeview box (or idTV) mains back in;
5) do a complete scan for channels - it will fail without the aerial. (This may be in the installation or initialization menu, and is distinct from any 'add channels option'). Once this is done your channel line up should be empty;
6) reinsert aerial by reconnecting to the 'RF in' connection;
7) do a complete scan for channels again.
The Freeview channel line-up provided by six "multiplexes" - each of which carry five or more TV channels, radio channels, text services and EPG data. In this diagram each ROW represents a multiplex. If you are still missing a whole multiplex (ie everything on the row) you may need to replace your aerial with a wideband type, purchase a larger aerial or you may have interference from a VCR, games console, Sky Digibox or similar.
I have recently been experiencing a weak HD signal each evening at around 19.00 hours onwards. The picture becomes distorted or fails completely with a "weak signal" message. During the daytime the reception is normal.
I have changed the aerial leads and checked the outside Freeview aerial without improvement.
Can you throw any light on what may be causing this problem?
Vic Quaglieni: We need a postcode to help, plus signal strength and what mux your watching. If its happening at the same time each day, that sounds like single source interference - any switches, etc that come on around that time?
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.
Hi, I did have the HD channels 101 to 106 but they've now disappeared. Understand they're all on the same mux. Presume it's because I'm on the outer edge of reception from the Wonershtransmitter. Any chance I could switch to a better signal? If so, how?
I have a new Sony TV with built in Youview.
