Paul,
If you have a proven back plate then it should be straight forward. If your visual inspection shows nothing to be wrong with the membrane then you have leakage somewhere on that panel. Set the bias at the level that would have been correct for the other panel that works correctly, then listen for any low level hissing noises.
