Official Wells Gardner D9200 Schematics and Troubleshooting Guide not matching?

Hi all,

When I go to this page:
https://www.wellsgardner.com/service-support/

..and read through the D9200 Troubleshooting & Repair Guide:
http://www.wellsgardner.com/wp-content/uploads/2016/08/D9200_27_33_39_inch.pdf

..particularly the "No green" symptom which is what I'm having atm, the suggested causes are "IC201, R236, Q207". So far so good.

Now when I open the schematic:
http://www.wellsgardner.com/wp-content/uploads/2016/08/D9204_D9205_Schematics.pdf

..it does correspond exactly to what I see on my boards, and I do find IC201, however no Q207 anywhere to be found. Same thing with many other components of the Troubleshooting Guide.

1) Am I missing something, or is this simply because the D9200 (troubleshooting guide) is actually quite different from the D9204/D9205 (schematic)? (Which would make WG's support page quite misleading!)

2) If so, would anyone know where to find a Troubleshooting Guide for the PD279200 with neck board PN279200, which seem to be what I have? (I know there's a lot of info on this forum but I'm wondering if there would be an actual "formal" equivalent of the Troubleshooting Guide above but for the model I have.)

Thank you heaps!
