Hi guys. Is there a guide on how to diagnose lamp matrix issues? I did not find one in pinwiki.

The issue I'm having is that Column 6 (juwel inserts) is dead.
I measured the voltages on power board and I'm getting something from J137-5 and 7 (working columns), but not from 6 (dead one).

Does that mean that the Q93 transistor is bad?
