Monitors of this era typically had x and y film caps that tend to self-destruct after some years. They are usually packaged in plastic that was not yet known to become brittle and crack

Can you elaborate on that? I've pulled and tested four film caps near the deflection coil connector and they all test good. I don't see any visually damaged components.

Not around the deflection. They would be close to the AC power input area. They would be "safety caps", such as an x or y class cap intended to operate across the input voltage.

That would be my first thought if it isn't turning on.

You can verify it by checking the voltage from the plug up into the PCB and see where things go wrong. Obviously it's line voltage, so be careful.
