Behringer pmx2000 has sound from the monitor/ left power amp only

[marlow]

I have a very used Behringer pmx2000 that has no sound on the Main /right side of it at all!! The monitor/left and the bridge/center seem to be in great working order how can I fix this issue?

you can start by digging up the schematic and posting it here.
Behringer is a very difficult company to deal with because they don't support the customers or techs with schematics or parts.
I am not saying that it is impossible to find a schematic, it just takes some digging.
Enzo seems to think that the pmx 2000 is a copy of a Peavey XR 684. That might just help you.

Try to narrow down the problem.
Check that you have a signal on the L & R Out jacks.
If you do, then insert a signal into the PA L & PA R jacks.
You may simply have a dirty or corroded jack.
The fact that the amp works in 'bridged' mode seems to indicate that the output amplifier is good.

Thanks for that most wonderful schematic.
