I'm restoring a non-working MC I picked up recently. I've updated the power brick (bob roberts kit), installed a rebuilt A/R II and rebuilt G07 chassis. I'm currently getting no sound, green tint on the monitor, player 1 and 2 lights on and the pcb led is lit.
My voltage reading on the test points are below. Am I missing something? Does it look like I have a bad game pcb?
I also recently purchased a (working) mc pcb but getting the same results.
I'm leaning towards a bad pcb but wanted confirmation.
If these are in fact bad mc pcb's I'll need to research my next steps.
Thanks for any feedback.

-5 = -4.96
+12 = 11.8
+10.3 = 10.2
-22 = -16.6
+22 = 16.5

PS
Pins 1 and 2 (10.3vdc) = 10.4
Pins 4 and 6 (25vac) = 27.5
Pins 4 and 5 (12.5vac) = 13.6
Pins 11 and 12 (6.2vac) = 7.0
