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
