Im pretty sure this is to do withthe laser, try using a cleaning cd, put your head next to the player and listen to if the actual disc is moving inside.
this might evan be a problem with the cd motor.

HELLO
Find a Technics dealer in your area, failing that, any good electronics repair centre worth it's salt should be able to put the fault right for you. Won't be cheap though!

Use a CD cleaning kit and follow instructions, if this fails! the laser pickup assembly would need to be replaced, not cost effective to repair.

You need to get the service manual, get a scope (oscilloscope) and start tracing signals from the D-A converter to the RCA outputs. Most likely it will be a bad Op Amp or open Electrolytic Capacitor.
I have repairs at least dozen of these kinds of unit in my 40 years in electronics repair.
If you need my help directly, contact me.
