Hello, new user here looking for some clues on troubleshooting a problem with playfield lamps on a 1978 Bally Playboy. This is my first pinball machine, so I have a good deal to learn.
There are two lamps in the playfield that are not functioning properly. One lamp (the 2,000 point light in the bonus area just above the flippers) never illuminates and with the machine in the lamp test mode, I have determined that there is no voltage at the socket.
The other lamp (the #3 light in the Playboy Grotto area at the top left of the playfield) is constantly on and with the machine in test mode, that lamp alternates between bright and brighter, rather than between off and on as the others do.
It strikes me as a possibility that these two anomalies are somehow related but I leave that to more experienced folks to assess. Any pointers?
Thanks much,
Richard
