Quoted from jorge5240:
My issue was that he sold me a "HUO" game that had a flasher issue and the wire to that flasher had been taken off of the board. I was a newbie and did not look in the back box at the time of purchase. I got it all fixed up and the game was in good condition but it rubbed me the wrong way. It would have been one thing if the flasher didn't work but it bothered me that it had been specifically taken off the board and it was a bad transistor so it wasn't like the wire had magically come loose.
Not enough to start a thread on pinside. I didn't have large issues like the op did but I decided it was the last transaction with him for me.
Mike, what pin was it?
