I just acquired a Paragon that seems to have an odd issue.
In test, all coils (including flippers) work properly. Some switches work (drop targets) and many do not (roll-overs, top saucer holes, start button, flippers).
In gameplay, neither switches nor coils/flippers work (including the start button, so it's not possible to add addtl players). The game does reset the drops at game start.
Rectifier board is brand new and connections are good (swapped it thinking that was the issue). MPU is the nvram.weebly.com Revision 13 from 2019. So I assume it's not any problematic male pins on the MPU as it's too new and they all look shiny. Checked all fuses with multimeter and all good.
I'm at a loss here...I'm not too well versed in these older Bally games. Any ideas?
