Hi, I can't get the board to go into test mode. A test switch is not wired, when I turn dip #4 on the pcb and power up it still goes into game mode. The service switch is wired but all I get is two service screens. Any suggestions? Thanks
 
Did you try using dip 3 or dip 2?

If I recall, some of the 'old' boards might have used dip 3 instead of 4 for test mode.
 
Figured it out

So I found the ground and put a new switch in connected to service wire. Test mode now works!
 
Yeah, that caught me out too, the 39-in-1s are different to the later 48 and 60s, you need an actual button wired up, you can't use dipswitch #4.
