maybe the jack sockets on your mixer don't make good contact
anymore. tightening the mounting nuts won't help then.
you have to remove the module, plug a cable into the
jack sockets and then push the contacts of the sockets towards
the jack with a small screw driver until they make contact again.
if this doesn't help then maybe an electrical part is broken.
