Having re-read your post, it looks like you might have your TV and
the Linn connected but you just can't get it to work.

If that is the case, you might need to go into the Menu on the TV
and make sure the Digital Output is On and set to the right Format.
I think the Linn might want to see PCM Audio.

I can't remember off hand all the different Formats that might be available
on the latest TV's.

I don't think an HDMI Converter is the way you need to go on this.
Stick to a Digital connection.
