I've just bought a 46" ES8000 TV and HW-E551 soundbar, and am having trouble connecting them fully.
First I attached an HDMI lead from the "HDMI Out" port on the subwoofer to the ARC port on the TV, which sounded great, but the soundbar wouldn't turn on with the TV.
Then I read that I needed to connect with an optical lead.
So I bought a lead, and connected it from the optical port on the subwoofer, to the optical port on the TV.
But the sound is no longer as good (weirdly) - it sort of sounds tinny and lacks bass.
But also, it still doesn't turn on with the TV. I have used the menu on the TV to turn Anynet + off, but the LEDs on the soundbar still say that the autopower-on feature "isn't available with Anynet + turned on".
If it helps, I am also connecting a Sky + HD box to the TV directly (ie. not via the subwoofer).
Help on why the sound isn't as good, and why I can't get it to turn on automatically would be great!
