SOURCE: sa-dx1040 dvd optical input works, tv and cd do not.
You have to manually select digital input on the receiver.
SOURCE: Technics SA-DX930. I ran digital optical cable
If the only thing not working is the optical input, it is possible that the optical converter is defective. Without seeing the actual unit and testing the IC, I can't say for sure. If you have test equipment, let me know and we will attempt to track this down.

SOURCE: digital optical output for technics 5.1 surround sound 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!"
SOURCE: digital surround mode doesn't work,just analog
Failure of the sound processor. All you can do is to remove the cover, clean the insides, check the cables to make sure they are still firmly plugged in and then measure the 5 volts power line from the source. If all appears OK the the processor has died - a replacement board is mandatory. It will be cheaper to buy a new receiver .
