I have a Denon PMA 2000R Integrated Amplifier. On a normal day, when I put my amp on, the power light blinks for 3 seconds and then a click noise sounds and the power light becomes steady. The amp is ready to play the music. Even when the input source is changed, there is a click sound after a few seconds and the amp is ready to play. Today when I turned on the amp, the power light started to blink as usual but there was no clicking sound before the light became steady. When I turned on the source, no sound was reproduced. Even when the source was changed, there was no click sound and no matter what source I put on, no sound was reproduced. I have checked all the wiring and there is no fault with that. In fact, I was listening to the amp before I went to sleep and the problem occurred when I woke up and put the amp on. Has anyone out there faced a similar problem or knows the solution to this problem? I am very distressed and eagerly await your responses.
