I've just set up my new 32fx68 and noticed something I did not notice when auditioning in the store. Its a faint, but constant and annoying line (approx 1cm high), running accross the middle of the screen when watching terrestrial channels. This line moves to down to about 1/4 the way up the screen when watching ecternal programmes via the AV sockets. Is it faulty? Is there a service menu tweak to get rid of it?
