I assembled an Out Run upright from parts I've acquired over the last three years.
I have it (finally) all assembled, but it's not working. I'm at the limit of what I know how to check.

The details:

Isolation transformer voltages look good.
Votage from the switcher to the PCB look good.
Coin door lighs come on, but don't seem to trigger anything
LEDs on logic board and video board light up.
Test / Service buttons don't seem to do anything.
No sound.

I don't have a CRT ready to go in here, so I tried a Gonbes board with LCD. Gonbes puts up a no signal type of message. I have a differnet converter board I've also tried. I can't remember the board name, but it was recommended in a thread somewhere. With the other board sometimes I get dancing green lines, or the other static pattern pics below.

I tested continuity for RGBS and seems good. I've checked the wiring for that many times. I do get about 3.8v out of the sync when it's powered up.

The main boneheaded thing I did was I initially had the RGB plugged into the pinout on the left side of the board instead of the bottom. That's not used in upright, so I'm guessing that's for deluxe sitdown. Possible I fried something there?

I tested for watchdog based on another thread, but didn't see voltage drops, so I think I'm good there.

I get 13v from the green and white wires that come off of the amplifier board.

Unless I inadvertantly torched the PCB, or it coincidentally died, I wouldn't expect it to be bad. I bought it refurbished from @parism and it litterally sat in the unopened shipping box in my basement for three years.
