Treadmill Display Flickers When Belt Starts

Answer: EMI noise from the board’s supply reaches the console. UpFix adds new filters and isolates ground to stop flicker.

Quick take: EMI from the MCB’s switching section feeds back into console power.

Signs

  • LED/console brightness drops only at belt startup

UpFix cure

  • Install ferrite chokes and new LC filters

  • Separate console ground plane

  • Confirm flicker‑free at 0–12 mph
