Need help troubleshooting BeoMaster 2400 ultrasonic remote circuit

Hello all,

I've just recapped a 2400 using Martin's kit, fixed the sliders, got everything hunk dory, and realized the left buttons on the remote aren't working.

I've tested the remote against another 2400, and it succeeds both left and right.  I've tested another remote against the newly recapped 2400, and the left buttons don't work.  Ergo, it is certainly in the BeoMaster.

I understand the left and right sides are tuned to different frequencies and that one of them is failing...sadly I don't know where to go from there.  My abilities to follow instructions and replace like with like are stronger than my abilities to actually troubleshoot circuits.

So, does anyone have any thoughts on what to do next?  Has anyone solved this before?

Replace the trimmer in the receiver circuit for the affected side (left or right).
(Or both).
