I am trying to replace my 555 bulbs on my Mr & Mrs Pac-man and started in the coin door.
At first, I couldn't get them into the sockets at all. I took a closer look and it seemed like the wires on both sides of the bulb were somewhat extended out from the bulb. I tried pressing them into the channel in the bulb, and was able to get two of them into the socket. The middle (red) light I still can't get in.
But to test the lights before screwing them back to the coin door, I turned the machine on, and when I did, the blue light gave off a tiny puff of smoke.
It still powered on and works, but what would have caused the smoke?
