Channel check/set info for pretty much all the NTL, Telewest, Virginmedia STBs, without needing unapproved engineer menu access!
Samsung 2100 and 2110: Press
TV,
OK and
Right at the same time. This will show the current RF channel number on the display. Then use the
Up and
Down arrow keys to change it to what you want, then press
OK,
Right and
TV again to confirm the new channel.
Take care, there is another command from the panel to lock/unlock the remote, I think it's OK/TV/UP and OK/TV/DOWN.
