Hi all, my first post here. Have had my Countdown for about 11 years and have done my share of maintenance and repairs. Recently I started doing some addtl maintenance and noticed on other videos when the game is over, other peoples Countown goes into a demo type mode where playfield lights light up. Mine, only the scores flip. Also, i can hear some sounds from the speaker sounding like a rocket but can barely hear it. I cant find any reference as to what option or things i can check. I have a niumph board and looked at that manual and my countdown manuals. Please assist if you are familiar. Thank you.
