SKUDE:

My Audya once again played perfect at last nights gig. I also played it for six hours during the day....perfect!

All I did was disconnect and reconnect every ribbon and wire connection I could find.

I don't know for sure which one or maybe more than one was causing my Left Channel Out Problem.

I suspect and recommend to you this: ( If you are still having problems with the audio outputs ).

The yellow and white and short black wires connecting the Sound Board and the Top Right Panel Board I believe is where the connection problem lies.

I know you have replaced most if not all of your PCB's in the keyboard and the ribbon connectors had to be unplugged and replugged in to do the replacements.

However did you unplug and replug in the connector on the ( Top Right Panel Board? )( Yellow, White & Black Wires. ) Probably not! Really no reason to do that when replacing all the bottom PCB's.

I strongly suggest trying that! Also try cleaning that connector with a little rubbing Alcohol and a Q-tip while disconnected. Disconnect and clean the connector at the Sound Board also. Also check that the top panel board's mounting nuts are all snug just for good measure. Mine were all snug.

Again, I can't say for sure that connector is the culprit, but through a process of elimination I suspect it is.

Give it a shot....nothing to lose! Maybe finally like me you'll get rid of the Aggravating Left Audio Out Problem!!!!!

This suggestion also applies to any of you out there having Left Audio Out Problems.

Let us know the outcome.
