WG46xx no green, narrowed down to P317 daughter board
Green crapped out on my Pac-Man's 46xx. First checked for continuity in the green video feed in the game wiring and between the chassis & neckboard. All good there. Then tried changing the green transistor on the neckboard. Still no green. Finally decided to pull the P317 and try it in another game I have with a 46xx. Problem is following that board. So I am thinking maybe a bad transistor there? Just checking in to see if I'm heading in the right direction here. The transistors on P317 are 2N3904's. I do have 2N5060's on hand, but I'm guessing those would not work. Can't really make sense of the datasheets.
Anyone want to chime in here?
