K3 - Error on power up , sub-rcvr removed

[BYRON]

 I have found a seller of a non-working K3, serial # 6000's ,  he states " the radio powers up with an error message,
Radio thinks sub is on, when not actually installed.  Trying to mitigate some risk here, I am an IPC Certified electronic technician , I have a test bench with the normal average electronic repair equipment to repair circuitry etc.  ESD practices observed as well. I am simply looking for someone who has removed a sub-receiver board or installed one that could shed some light on what the original owner of the radio may have done incorrectly when removing the sub-rcvr board. Is it as simple as a menu selected setting , a jumper board not installed etc. The seller hasnt been able to identify what the original seller did other than just remove the sub board.
