A Denon AVR-590 has been stop outputting anything to the speakers occasionally. In the past, I applied the "resetting sequence" a few times and it came back. This time, it seems to be gone for good, although I can still get sound from the headphone jack.
This happens to all input sources: AM, FM, DVD, etc. Sometimes I can hear relay(s) clicking for no reason inside. But I am not sure if the click of relays always lead to it having no sound.
This is my first posting in this website. If this is the wrong place, please let me know. A pointer to the right forum for modern stereo repair would be appreciated.
Thank you!

if you can hear music with a headphone,
it is probably coursed by the defective speaker output relays or the protection circuitry,
if you tap slightly with a plastic bar on the case of the relay and it resume music on the speakers. then clean the contacts inside the relay or change it .
if you hear relay clicks for no reason, may be its the protection circuitry problem.
you need to check the voltages of the amp power supply. but
are you experienced in this field,
if not, find someone who knows what to do with it,
its dangerous inside because there are fatal AC inside the amp.

Denon is particularly tricky. Not for the inexperienced, even pros do not like to work on them.
Just spray the headphone socket with contact cleaner, and work the pin in and out a few times. Might just be a bad contact. Do it from the outside.
And bear in mind that some Denon designs use high voltage supplies in the power amp section, sometimes up to 120 Volts.
Be very careful.

NareshBrd is right,
blow strong air into the headphone hole,
or blow 3 in1 cleaner into it to clean the contacts which will mute the speakers when headphone is plug in.
hope you fix it soon.

The previous post, while sounding weird, has
Value.
I have a denon receiver similar to yours.
I also had the same weird "speakers stop working" problem.
I the end i unplugged the headphone pcb. There's one plug which provides audio for the headphone and also some form of detection for the headphone.
It is this detection that fails, and compressed air helps some.
I don't use headphones soi simply unplugged the thing and have never had an issue since.

I unhooked a connector from the headphone board to the main board and it works like a charm!
Thank you!

yes it has 🙂As a new poster all your posts need to be approved by a moderator before being passed.
