Hello Giannis, the indication that appears on the screen, can be for several reasons, malfunction of cassette players, malfunction of the compactera and / or malfunction of the speaker output, in the worst case the audio output, scorched
If you have technical knowledge, you can try to disarm the equipment and go disconnecting, the flat cassette connection tape and fix if it starts, if it does not, leave disconnected and disconnect the flat tape from the compactera and the multi-legged cable that comes from the mechanism of the compactera, try again, if it still continues, you should check that you do not have direct current in the output of the STK4211
Otherwise, you will have to take it to a specialized technical service
Note, in this Sony model, you can not join the speaker negatives, since they do not have the common configuration, the audio outputs are Bridge type
I hope you can solve the problem, comment the results
Greetings Franco Dosil
Hola Giannis, la indicacion que te aparece en pantalla, puede ser por varios motivos, mal funcionamiento de las cassetteras, mal funcionamiento de la compactera y/o mal funcionamiento de la salida de parlantes, en el peor de los casos la salida de audio, quemada
Si tienes conocimientos t?cnicos, puedes probar de desarmar el equipo e ir desconectando, la cinta plana de conexi?n de las cassetteras y fijarte si arranca, si no lo hace, deja desconectado y desconecta la cinta plana de la compactera y el cable de varias patas que viene del mecanismo de la compactera, prueba nuevamente, si aun continua, tendr?as que revisar que no tengas corriente continua en la salida de los STK4211
Sino, tendr?s que llevarlo a un servicio t?cnico especializado
Nota, en este modelo de Sony, no puedes unir los negativos de parlante, ya que no tienen la configuraci?n com?n, las salidas de audio son del tipo Puente
Espero que puedas resolver el problema, comenta los resultados
Saludos Franco Dosil
