Greetz all, I have been troubleshooting the complete lack of matrix lamps working-either columns or rows, on my latest DE Star Wars pin. Mains and Flashers work fine, I have gone through diagnostics, nothing seems amiss there, other than none of the matrix lights work. I followed most of this troubleshooting here -http://techniek.flipperwinkel.nl/desega/index3.htm#lamp, but nothing sticks out.
I checked impedance across resisters with no opens (R55-R62), I have checked for burnt fuses at F2 and burnt molex G.I connectors, as well. Right now, I am not sure what I should look at next. Because its the entire matrix of columns and rows that do not light, if feels like it should be a fuse. Help would be appreciated. Thanks in advance.

ChrisHibler thanks for the suggestion. This started a whole other process which I wouldn't have thought to do in the sequence I did, without some feedback. I tested for 18VDC, and got intermittent voltage when testing w/ DMM, from one side of the connector to another. I reset the connector, and all the matrix lights go on...awesome!...intermittently. I then followed power back from the board to the transformer to see if/whether there is something causing this, or was this a voltage irregularity. I found something in the transformer molex connector, which seems to be causing a problem as well. One side, completely smoked. I'm not sure how I missed this before. So, I clipped it out, and used some wire nuts temporarily to see if that might be the solution, before re-terminating these. Sure enough. works like a charm. All matrix lamps on, all the time.
