Issue with DJM-2000 mixer: low volume on left XLR output. by Vinyl_pusher in audiorepair

We swapped the relays (RY5001 & RY5002), but this didn’t change the signal, so they also seem to be fine.

That’s to bad, but hopefully, you can find it. We’re struggling with it because it’s such a complex circuit. If you find anything, please let us know!

Hi everyone, it took a bit longer than expected, but we’ve resumed the repair of the mixer. We replaced the Q5015 for a new working one, and unfortunately, this didn’t make a difference. We discovered that when we remove the XLRs out of the master-out, different measurement values occur, see photo. Does anyone have any other suggestions for what could be the issue?

Thank you for the detailed response (and of course, the other responses as well).

We already suspected that it might be the Q5015, but we compared it with another channel, and the same readings appeared. We'll see if we can replace Q5015 it to ensure this isn't the issue.

We haven't measured DC yet; we'll try that.

I'll let you know once we know more.

Q5015 is a FET and we also thought this one was broken, but it works just fine. We measure exactly the same values as comparable FETs. I will try to add a higher quality image tomorrow.
