Carried out a retune on a Tecknika ( Tesco) tv on 4th April and lost a lot of channels that previously did work, including BBC 1 and BBC2. Retuned again on 18th April and have now lost Viewable channels even though the TV retune reports it found 90 channels.This retune stuff is something of a farce, I bought this TV in Sept 2010 and it has built in Freeview, I would expect a longer life from a TV than just 18 months.I now have no tv, Tesco are saying it is out of warranty and not their fault, so it might mean a visit to Trading Standards.Who else can afford to just lose the use of a TV on a government related retune.

Hi,
Some of channels have offset, is this something that can be adjusted in a standard set top box? Is it important, will it give improved signal, or does settop box just tune to it automatically?
Thanks.

Nick: The ofsets on the channels are a technical network matter, and 99.99% of set-top boxes will discover them.
They are used to provide a small "buffer" against the bands used for the DDR (4G mobile services).

If you have a 2K mode unit you will have losted BBC on the 4th April as they moved to 8K mode. And as of today you will loose the rest as the all swtich to 8K mode. If this is the case as with manny of the original cheap boxes or early TV sets. you will need to buy a new box.

I have a non-High Definition PVR; presumably it's normal that a service search shows no channels on former analog channel 20 (PSB3), and this will never change?
I'm sure a lot of people who have noticed this will be confused at a multiplex showing as 99% signal quality on their equipment, with 0% quality.
Thanks

Previous message typo; where I said analog channel 20 I meant 30.

Hiya, I have retuned and seem to get all the channels but there is a strange problem : some channels like Yesterday, Film4, ... have a channel number greater than 800 instead of their usual number (smaller than 100). Anybody has an idea why that could be ?
