Aragon 4004 power light on but no sound

Hi all,

I have Aragon 4004 power amp that has an issue: It used to work well, however i just turned the amp off and in 10 seconds I turned it on again then I found it provided no sound. The power light is still on now. The aragon preamp has been tested, working well.

Does Anyone have any experiences and ideas? I appreciate your time reading this.

Check the internal speaker line fuses.

Yes, check the rail fuses. But since it appears that both channels are dead it might be a fuse (or problem - faulty power switch?) related to the power supply. More likely that than two (or perhaps four) rail fuses blowing simultaneously.

Thanks for replies.
After a night, the amp worked again. But as soon I turned it off and on, I had no sound.
i ll check the rail fuses as you adviced.
Thanks again.

The amp does have a relay that mutes the output at initial turn-on for 3-5 seconds. It might be if you are turning it off then right back on, the relay hasn't had time to reset. Try leaving it off for a few minutes, then turning it back on.

Also, like Partial stated, it could be a faulty power switch and/or relay itself that is causing the problem.
