Yamaha MG32/14fx Auxillary output issue

[Callahan]

I am new to the church and we have small speakers that are on the wings that have not worked since I started there. I've worked on smaller portable mixers at our old church. Two weeks ago all of the other aux monitors quit working.

Issue #1 - The Wing speakers were plugged into the R-Main bayonet jack. I moved them to jack to the L-Main and they worked ok. Could the Yammie port go out like that?
Issue #2 - I went in tonight and confirmed that the wiring is ok with some tracing tools that I use for networks. I wondered if the Yammie could be having a problem, so I unplugged both L-Main and R-Main. After doing this all of the Aux speakers including the choir monitors started working fine. Is this a sign that we are about to lose more functionality?

There are 4 Amps involved. One for the Mains and the others are divided into the reamaining 3 amps. If we were having an amp problem, I would expect a different result from just unplugging the main at the board.

Any ideas would be helpful.

I spoke with a local sound company and we are going to investigate the wires on the stage to see if there is a wire crossed somewhere up there. If not then we will investigate the board.

We went through the connections to the board. We did find that there was one unused monitor cord under the piano that had was not connected to a speaker. The wire ends were not taped up and that may have been shorting out causing the board to isolate the circuit for protection. After taping this up and doing some other misc cleanup on the use of the board we had a good Sunday with no real issues. So, we hope that it will continue to work well for a long time.
