Whoops!, yes the test points are there, I accidentally cut them off on the right when I screenshot the schematics.
Hmmmm, that's not correct. You shouldn't have any DC there. Set the meter to AC setting. You should have around 19-20 volts AC. If you don't have that coming into the board, you won't get your +5VDC logic power so we'd be working our way backwards upstream. If you have the 19-20VAC coming in then proceed to the following:
At the edge of the board by the giant heatsink for the regulator transistor, you should see wire attachment points for the regulator transistor labeled E, B and C.
Set meter to DC, and measure from ground to "C". Should see about 11VDC there. If it isn't, then set the meter to AC and take the same measurement. You should see around 40mV or less. If you are measuring much higher - in AC volts instead of millivolts, then one or more filter caps are probably bad. If the DC voltage is not present, probably the bridge. I would then remove the board and take some rectifier measurements or cap measurements to confirm, since you really have to get to the back of the board to do this. Also, would check for cracked through-hole solder joints on the back.
The regulator transistor wire labeled "B" should be around 6.77VDC, the point E would be your pre-conditioned logic voltage - about 5.4VDC. You can use standard transistor testing with the game power off to check the transistor.
