Technics SA-DA 8 analogue inputs and outputs are not working. Optical in and outs are working just fine.

You have to manually select digital input on the receiver.

I went to the HDTV plasma manual. It stated the only way the digital optical audio output would work (from this TV) was to go to the menu, select audio and turn off the TV speakers. Basically, it had nothing to do with the technics receiver.

Testimonial: "worked like a champ!"

hello there are 2 big capacitor behind the metal heatsink see if one has swelled up if so change them both then check the output chip to see if there are any dry joints then when you've check all and still the same then you may have to change the output transistor g ood luck

What model TV? Are you sure the optical jack on the TV is an OUTPUT and not an INPUT?

When you say you have sound from the BD prior to disc load... where (TV and/or receiver)? Initial wake-up audio is usually 2-channel.

Describe the optical audio connection input to the receiver and any other audio paths that are attached.

Do you have other multichannel sources you could use to test this, like a cable TV box?

There's an obscure setting in the receiver called PCM Fix (on Page 21). Give that a look.
