Hi there,

There could be a number of reasons as to why this could have happened, your system could have run it's auto update which wasn't successful. Try going into your setup and running the channel update, this should then reload the channels including the ITV channels.

Hope this helps,

James

These will have been rolcated to a different channel number. You can select the programme guide & scroll through all the channels until you find thier new location number, then you could either take note of these new numbers or go into the set up menu where you can re-arrange the channel numbers back to 4/5 etc or set them on your favourites listings

Hi, I had the same problem, try removing your aerial from the box - retuning and saving so it blanks out all previous channels and then reattaching the aerial and doing another retune, this worked for me. Good luck.....

I had same problem, first reset to factory default (code should be 1234) then keep trying the auto tune. It took me about 10 goes over different days since wedn 30th, managed to get all channels last night 1st Oct.

Can you try a non-working box in the Thompson box's location in the lounge? If you swap the boxes in the lounge and they both work normally then you must suspect that the cable supplying the conservatory must be the problem.

I think you need to get Sky because it will give you 100% coverage of all terrestrial channels. You may need to retune the television otherwise just get sky

I've got exaclty the same problem :-/
HELP!

This is due to NIT in DVB-T transmission

Digital UK estimates that "only 1%" of Freeview receivers are susceptible to this change - technically, the introduction of a multi-part Network Information Table within the digital data.

The effects on some of those STBs and VCRs are plainly malfunctions, such as abnormal channel numbering e.g. Channels may be listed, but they're assigned to all the same number or assorted incorrect numbers. Alternatively, no pictures are seen, despite all channels having high ratings for signal strength.

Any luck? I lost channel five to channel 802. I want to change it back to it's slot after channel 4
