  • 4 Check if the circuit board is working correctly (indicator lights):
    • 4.1 Red light indicates power supply is working
    • 4.2 Yellow light indicates CPU is working
    • 4.3 Green light indicates signal is working

  1. Power On, Resets But No Light:

  • 1 Check if the bulb is good and properly installed
Light bulbs that generate the necessary brightness for professional stage lighting.

  1. Lights Reset After Working for Some Time:

  • 1 Unstable output from the power supply
  • 2 Loose or poorly compressed wiring causing poor contact, leading to automatic reset

  1. Bulb Turns Off Automatically:

  • 1 If the bulb turns off and later turns on again by itself, check if the cooling system is functioning properly. If there’s a cooling system fault, the bulb may turn on again.
  • 2 If the bulb doesn’t turn on again after going out, the bulb may be defective (e.g., surface whitening, internal blackening), and the bulb’s life has ended.
  • 3 If the fixture has been without control signal for a long time, the bulb may enter automatic protection mode and will light up once the signal is received.

  1. Bulb Lights, Motor Resets Normally, but No Control:

  • 1 Check the signal connection (DMX)
  • 2 Check the fixture address code
  • 3 Check if the signal IC (75176) is damaged

  1. Fuse Blows or Power Supply Trips After Powering On:

  • 1 Check if the ballast is short-circuited or if the inrush current is too large during power-up
  • 2 Check if the bulb is grounded
  • 3 Check if high voltage inside the fixture is short-circuiting to ground

  1. Bulb Lights but Cannot Turn Off:

  • 1 Check if the “Electronic Ignition Off” setting is enabled in the menu
  • 2 Check if the thermal switch is short-circuited
  • 3 Check if the ballast is faulty

  1. Bulb Lights, Can Be Controlled, But Not White After Reset:

  • 1 Check if the distance between the Hall sensor and magnet is within 2–3mm
Hall sensor detecting the strength and direction of magnetic fields in lighting fixtures.

Magnetic Field Sensor for Precision Lighting Control

  • 2 Check if the fixture is properly zero-positioned

  1. Motor Shaking or Losing Steps:

  • 1 Check if the motor is short-circuited, causing IC (3711) damage
  • 2 Check if the mother board is damaged
  • 3 Check if screws on gobo and color wheels are tightened properly
Moving head fixture with color and gobo wheels for versatile stage lighting effects.

  • 4 Check if the Hall sensor and magnet are misaligned

  1. Channel Component Sticking:

  • 1 Check if any parts are deformed, causing rubbing
  • 2 Check if parts are properly installed
  • 3 Check if any parts have fallen off, causing jamming
  • 4 Check if the stepper motor is malfunctioning, causing the motor shaft to lock

  1. No Display on the Display Panel:

  • 1 Check if the display panel is damaged
Motherboard mainboard for event lights, offering stability in controlling and monitoring lighting fixtures.

Control and Monitor Lighting Fixtures with Reliable Motherboards.

  • 2 Check if the 7-pin ribbon cable connecting to the display is loose or damaged

  1. X and Y Axes Losing Steps or Unable to Position:

  • 1 Too much dust on the optocoupler, causing infrared light to fail to reach the target position
Optocoupler component for bar stage lights, ensuring isolated electrical circuit interconnection through light.

Essential Optocoupler for Bar Stage Lighting Safety and Control.

  • 2 Optocoupler board is damaged, or the distance between the optocoupler wheel and optocoupler is not adjusted correctly (ensure the optocoupler is centered with no scraping, bumping, or rubbing)
  • 3 Check if the stepper motor mounting screws are too loose or too tight
  • 4 Check if the belt fixing screws are tightened
