Panasonic G30, how to turn off speakers?

[MichaelHo]

My fiancee just bought me the 50G30 for my birthday! Very lucky guy indeed.

I have a yamaha amp with bookshelf speakers I prefer to use rather than the TV speakers, from scrolling through the menus I cannot find anywhere the option to turn off the TV speakers. Does anyone know how to do it?

Never mind, I just turned the volume to 0 and as it's optic out it doesn't affect the volume of the amp.

Just incase other users wanted to know how, I've found it.
Click on viera link button and choose speaker to Home theatre. Since doing that my tv remote now controls my amp volume! It's so good.
It also turns amp on automatically when tv turns on and then turns amp off when i turn tv off.
