Displays stopped working. All fuses are good. I can only assume it's some wire that's loose. Any leads as to which one? I've followed display wires to their connectors. All seems good. I'm obviously missing something.
Thanks in advance.

Can you elaborate on where to check snyper2099 ? I'm still becoming familiar with SS :/
Transformer to power board to displays? Would that be correct and a wire is loose somewhere?
Sorry I'm inept still learning....

It is probably not as simple as a loose wire, those displays run off a high voltage power supply in the backbox. That circuit is probably the culprit see the link Atari_Daze provided above.
There's test points on the displays, check the schematics for which points are 170VDC and GND and see if you've got voltage. If not, go check the TPs on the driver board
got a high voltage kit and replaced all parts. displays work now
c26 had a big bulge on one side. pretty old i assume. im glad it didnt explode.
i had tried only replacing some parts at a time. (c26 first, then resistors that looked funky, then all transistors...)
it took replacing all parts before it worked. a lesson against laziness lol.
thank you all for the info. it lead me in the right direction.
