Hi,
I suspect my Pioneer VSX-D608 has a power supply issue. When I turn it on from standby, the screen turns on and there’s sound from the speakers. But after a few seconds, or after I turn the volume up, I hear the main relay from the power board click and after that the receiver restarts.
I wonder how to troubleshoot this issue - what is the main reason for the relay switching? is the system shorted somewhere or is it a bad component?
Thanks!

It is called a speaker relay. It is there to protect your speakers from DC current burning them out. I could be that it just needs adjusted to lower the DC offset 99% of the time when the red protection light comes on or the relay does not make a sound or turns on then off, it is a bad component. It will need to be looked at by someone who is familiar with electronics.

@travisjfox thx, already got the manual. I have knowledge in electronics (I'm an electronics engineer) but no hands-on experience with working with complex analog circuits. I am wondering how to approach this and what I should look for first, just to get started

@yoniizu If you have the remote that goes with the device take the batteries out and turn the device on manually. I've seen dying batteries in the remote cause something similar in a Phillips brand player

I tried both with and without the remote, same problem...

@yoniizu Were the batteries removed from the remote?
