nishijin lighting problem
i have this nishijin machine. it runs fine and pay off fine. but there are a few lights that do not work. i have pointed them out in the pictures. i have done some little things like clean the pins and changed all bulbs. i have checked continuity on the wires. also there are no burnt traces and all the ic chips look fine. no heat damage or swelling.
i am stuck here. at times i think some will only light up when certain criteria is met during game play. i do not know.
i guess the easiest way to fix it is to replace the printed circuit board. the second easiest fix would be to have some schematics. i have neither. any help here?
thank you,
Gary
