Amplificador Onkyo DR-645 "petardea" Ruidos o Picos de señal
Tengo un amplificador dvd Onkyo DR-645, que desde hace algún tiempo, como a los 5-10 minutos de estar encendido, emite sonidos muy fuertes, como picos de señal, o interferencias. Son ruidos como de disparo, que se repiten varias veces. A veces termina fallando un canal, que se queda sin sonido. Si apago, se restablece, pero a los 5-10 minutos, otra vez los mismos ruidos.
Alguna idea de a que puede deberse, ¿y cómo podría solucionarlo?

¡Gracias! Al final era el circuito integrado. Se había dañado, y hubo que sustituirlo. Me lo solucionó Cañedo S.A.T. en Oviedo (Asturias), por menos de 60€
