Hi Jan, there is a fuse that you should check, if it was burned, replace it only by one of equal size, never of greater value, it could be drastic
The switch of your Technics, is electronic, works with a relay that connects the power to the main transformer
This electronic ignition is powered from an auxiliary transformer (Stanby)
If you hear a noise when you press the Power key, it means that the relay is working and you should check the fuse that tells you
If you do not hear anything, the auxiliary transformer could be wrong
I sent you the link of the service manual of the Technics SA-GX690, which is the same in this part of the circuit
I hope you can solve the problem
Greetings
Hola Jan, hay un fusible que deberias revisar, si estuviera quemado, reemplazalo solamente por uno de igual medida, nunca de mayor valor, podr?a ser dr?stico
El interruptor de tu Technics, es electr?nico, trabaja con un rele que conecta la alimentaci?n al transformador principal
Este encendido electr?nico esta alimentado desde un transformador auxiliar (Stanby)
Si escuchas un ruido cuando presionas la tecla de Power, quiere decir que el rele esta trabajando y deberias revisar el fusible que te comente
Sino escuchas nada, podr?a estar mal el transformador auxiliar
Te env?o el link del manual de servicio del Technics SA-GX690, que es igual en esta parte del circuito
Espero puedas resolver el problema
Saludos

just an idea maybe check the position of speaker select switch some models have
a or b
or a+b
SOURCE: My Technics AV Control Receiver SA AX530 is in overload
An amplifier should never be turn on without speakers, it will overload internally.
make sure speakers work and try again.
