I have problems with my sony bravia kdl-26v4000 i tried to reset the digital freeview which is built in a while ago and that has some how disappeared and i tried doing it again today by auto tuning it and now no channels are appearing how can i reset it so that both analogue and digital channecls appear ?

Chances are that your reception just isn't strong enough to receive the 'less-commercial' channels. Happens to us all.

Not that this is really a 'solution', but I wasn't going to post it as a 'clarification request'.

Anyway, sorry for being the bearer of bad news.

Sounds like you cant have set up the scart cables properly. Im unimpressed with BT for not setting it up for you, why didn't they?
Plus you will not need the freeview box if you have BT Vision, so i would take out the freeview box and just connect one end of the Scart lead into the back of the BT Vison box then put the other side of the lead to the Back of the TVs scart socket. Then all you need to do now if change the channel to AV1 OR AV2 or whatever channel you have.

We had this trouble with our sony bravia, had to get a repair man in to look at it and the digital tuner within the tv went cost $180.00 to have a new digit tuner put in.
