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.
thanks

Rotendog used to be on pinside. Until they were called out with all their problems. Great Lakes pinball didn’t make it. I got old school flippers boards, for TZ. From a guy in NY. They were made in Australia. Adjustable tension, leds, love them.

Yes, refund. Your original board lasted for many years.

LOL
This problem goes back over 9 years.
I do have some Rotten Dog boards. They seem fine. Build quality, they are no Great Lakes boards. My friend has a couple Sega machines and these flipper boards. They are not reliable.

Strange how all these boards have so many problems. Nice to know information.
