Older Technics Receiver; right side no/weak sound-staic. Tried different cables, switched speakers L to R...the red/right terminals seem to not be working
The output transisters for that side are probally blowin,
SOURCE: Technics SA-DX950 intermitently sounds blown out
There are poor solder connections at the output amp pacs and the voltage regulators. Once these are resoldered the problem should go away. If you can solder, resolder any connections that appear grainy or have rings. If you can not, this should be effectively a labor only repair for any shop that works on audio gear.

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: Max. wattage for speakers w/ Technics Receiver SA-GX100?
I too have a Technics SA-GX100 and it's rated at 2 x 40W @ 8 Ohms. I have the Technics SB-2840 floor model speakers hooked to it, which are rated at 200W Music Input - 8 ohms. It sounds very nice just to be a 40W receiver.
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!"
If it's only an analog source doing it I would suspect a bad audio cable or a switch contact somewhere in the signal path. Typically, it might be a switch you rarely use, like a Tape Monitor or Mute. It's wise to occasionally (with power OFF) manipulate all manual controls throughput their ranges a number of times to wipe oxides from their contacts.
