Sounds like an interruption between the BBD output and the corresponding
socket on the front panel. The internal signal path is as follows:

internal BBD output (which is obviously working) -> BBD output socket ->
Feedback socket (via switching contact of the output socket)

The first connection (internal BBD out -> socket) is made via one of the two
5 pin connectors. Maybe one of the cables is loose or there is any other
interruption.

If you cannot find the fault please send the module for service/repair to
the dealer/representative where you purchased the module.
