DJR400 - Left Master out (XLR) not working

I have a 3 year old DJR400.
The Left XLR master out doesn't work, no sound AT ALL.
Does anyone know how to fix besides sending it back to Jerome?
Thanks, Rob

Jerome contacted me. he said best way is to find someone in the states that will fix it (shipping to and from france would be ALOT). Does anyone know of a qualified repair person, prefer someone who has worked on this specific mixer before!

Dead output, should be pretty straight forward to find yourself no?

Just to double check the silly things first, you have checked the output with other cables and another input thus eliminating the amp and cable?

When you wiggle the xlr plug in the back you still get no sound?

Take the mixer apart, how is the XLR socket mounted? Board mounted or wires?
What's the solder joint look like?

If all of that is ok, trace back the signal, what's it going in to? any op-amps? bad looking components or solder joints?
Perhaps ask Jerome what's feeding the XLR out and look there with a scope.
Had the left output go on my Akai S-1100 recently (Was very hissy) and took about a week to find the faulty op-amp but I did have the schematics.

Judging by this photo the XLR sockets are not board mounted and at a guess could be a dry solder joint or a breaking down ribbon cable.. Give it all a good wiggle if all that's ok I'd guess it's a faulty op-amp

Thanks for the reply vinyl junkie, yes i did the cable swap, wiggle test etc... it is def getting no sound at all from left master XLR, nothing. Jerome said it was prob a bad output line driver. Not sure how or why he came up with that because i gave him no details other than the fact that i'm getting no sound at all. If that is the case, the part relatively cheap but i have no experience repairing these things.

Only way to confirm if it was would be to place a test signal on the input and probe the voltage until you find where the voltage goes to zero. Those 4 x op-amps driving the XLR's are soldered to the board and the PCB tracks on the 400 are a little delicate. I would not advice doing this yourself unless you have good De-soldering experience as ruined tracks is worse than a faulty op-amp.

Hey all.. I've got serious issues w my E&S 400 mixer and looking to get some help.
I bought it new from E&S and it's had problems since day one. Sale and delivery went smooth.. but as soon as I let Jerome know I was having problems he pretty much stopped answering my emails? Looking now for someone who can work on these in the states so the shipping don't hurt so much? See a lot of talk about Mario G on here. Guessing he's the man? Anybody else?
A contact would be greatly appreciated.
My shit is totally fucked on all the line channels, cues cut in and out and wont monitor in stereo. Right now it's basically $3k paper weight.
Thanks, t
