I hate matrix issues I never have any luck (idea) on how to fix them.

So I have a BSD and the 'R. Ramp 2 Million' lamp is lit when any of the others are also on in the same row, most of the lights if not all are boards so the diodes are on PCBs is there an easy why to try and diagnose what and where the issue is?

I did try a multi meter on the power board pinouts but I guess I need to use a probe, so another question is; (as I have a probe) how do I use it and check the power boards pins to see if its a cabling or power board issue?

As an update;

I had to pop in another power board to fault find another issue whilst in I tested the lamp matrix issue and it was no longer an issue.

So its a power driver board issue I bet transistors.

Thanks for your help folks.
