After installing pinled score displays on my Bally "Paragon" I now have a loud hum over the speaker when its in atract mode.and when it switches to high score to date it gets louder.
When I toouch C10 on the score card I can hear (believe this or not) a radio station.
Anyone have an idea? I cleaned where the ground contacts are made on the board to the backbox, no real difference.
