Quoted from tonyf1965:
Thanks so much everyone. That we may have wrong transistors in their Rottendog FLP023 data east boards. I am helping a friend with his star wars machine. He also had bought one of these boards from them Rottendog FLP023. That has 2n5401 transistor for q1, q2, q3 on his. I will change them to 2n3906 for him. His q8 (IRF9530) is shorted, blowing f 3. I can fix both problems at the same time, and double check his flipper coil too.
I’ve got the same issue as above.
It looks like the q1, q2 and q3 transistors are still being shipped with the wrong transistors in them or I got an “old batch” board! The board I got has 2n5401 installed instead of the 2n3906.
I just purchased my “new board” in August 18 from K’s Arcade with 2n5401 installed. It worked for 3 months then F3 started to blow yesterday and after testing q8 it’s shorted apparently because of this issue. So disappointing to get something brand new and to not have the correct parts and take a crap on you after a few months.
I’m going to contact them and see if we can get this resolved quickly it would of been nice to have my game operational for Thanksgiving.
