hmmm... The counter sees the 30 Hz CTL pulse when playing. So maybe it's picking up 60 Hz hum or noise making it count twice the speed while sitting stopped? Strange one! I'd have to take a look at the PB CTL pulse output probably a test point somewhere, or maybe a pin on the servo IC for CTL pulse.

The video starting out dark like no luminance then gradually getting normal looking sounds like bad electrolytic(s) to me.
