Having purchased one of the above, I am using it with a Sony DB1070 Receiver. The 1070 has an audio feed from the phonos on the rear of the TV. My question is, "to enable the best audio quality from the rear phonos, one has to switch the internal speakers of the TV off. This is done, as i'm sure most of you know from the on-screen menu. The prob is that this has to be done each time the TV is switched on, even from standby the TV defaults to speakers "on". Does anyone know if the default can be changed to "internal speakers off"? I have access to the service menu, I have used this to great effect when combined with the THX setup info on various DVD's, but cannot find anything with ref to the problem mentioned. Can anyone help?
