Test for lamp voltage on the CPU board at either of the ends of the inductor. I suspect you don't have power. It is extremely unlikely that all columns or rows fail at once. I would not touch any of those ICs before ensuring that the power to your board is good.

Sorry. I incorrectly assumed it was obvious that I was highlighting the +18V track on the board. That big track masked by the solder mask is the +18V track. Any point connected to it is +18V. I made this assumption because what you wrote about what you did implied to me that you knew about how to follow tracks around.

Here's another attempt with a much more pointed annotation. There are other points but those are easily accessible when the board is mounted in the machine.

Oh. Sorry. You stated you measured at the SIP where the text is whereas I would've measured at the inductor or the pins at 1J4. If you don't have +18V at the board then check the actual pins and the connector - just to be sure. Beyond that you need to go upstream.

The 8A fuse...remove and buzz...is a prime suspect.
Next is the bridge adjacent to i.

If you've pulled the fuse, it tests fine and you have no +18V at the 1J4 connector (not header) then you likely have a problem in the wiring as outlined in the wiring diagram. Test at points further up the chain for the presence of +18V - i.e. at the positive lead of the bridge rectifier. If you get nothing from that then check the transformer secondary output wires (AC input to the bridge rectifier). You need to find where the problem is. It's going to either be active component (bridge rectifier) or the wiring. You say you've done a static test on the bridge rectifier so do an active test by measuring the voltage at the positive terminal. If there's voltage then you have a break in the wiring. Test continuity of the wiring.

There's not a lot in the wiring diagram. You just need to do the work because nobody else can do the work remotely.

If you're still unsure then post an image of the layout so someone can annotate it and guide you further.
