ADJ Vizi CMY300 troubleshooting

Common Vizi CMY300 errors & problems

What techs run into most, and what's usually behind it. The step-by-step fix for your exact unit is in Ask Roadie.

• Color / Cyan / Magenta / Yellow Reset Error

  Likely cause: The CMY flags and color wheel each home against a sensor at startup; a bound flag or bad sensor aborts calibration and reports the specific channel's reset error.

• CPU-B / CPU-C / CPU-D / CPU-E ERROR on display

  Likely cause: The main CPU polls sub-processor boards (motor drivers) over an internal bus; a dropped/failed board or broken data link reports as a CPU-x error.

• Dead unit / no power (blown fuse) and safe power-linking limits

  Likely cause: A blown mains fuse kills the unit entirely; replacing like-for-like restores power.

• DMX addressing and channel-mode setup for multiple units

  Likely cause: Each fixture consumes a block of consecutive DMX channels; addresses must be spaced by the active mode's channel count so blocks don't overlap, and the console personality must match the mode or every parameter maps wrong.

  Step-by-step fixGet the fix →

• Fixture not responding to DMX / erratic or no control

  Likely cause: DMX is a single daisy-chained differential line; wrong polarity/pinout, a split line, a missing terminator, or an address/mode mismatch between console and fixture all break or corrupt control.

• Gobo1 / RGobo1 / Gobo2 / Prism1 / RPrism1 / Prism2 Reset Error

  Likely cause: Each gobo and prism wheel indexes to a home sensor at boot; a mis-seated gobo, a jammed prism, or a failed index sensor prevents homing and throws that wheel's reset error.

• How to update firmware on the Vizi CMY300

  Likely cause: The CMY300 has an onboard USB firmware port specifically so updates are field-applied without a separate uploader; keeping all units on the current version fixes known bugs and keeps behavior consistent.

• Light smoke or smell during first use

  Likely cause: New fixtures off-gas manufacturing residue when first heated; ongoing smoke/smell instead signals a thermal problem (blocked airflow, failed fan) that must be ruled out to avoid damage.

  Step-by-step fixGet the fix →

• Overheating, thermal shutdown, or dim/flickering output during long runs

  Likely cause: The 300W LED engine is actively cooled; dust-clogged fans/vents or fouled optics raise junction temperature, triggering thermal derating (dimming) or protective shutdown.

• Pan Reset Error or Tilt Reset Error / Encoder Error on startup

  Likely cause: The head must complete a mechanical home sweep at boot; a left-engaged tilt lock, physical obstruction, or an encoder that cannot read position aborts homing and throws the reset/encoder error.

  Step-by-step fixGet the fix →

• Two or more fixtures behave differently (iris speed, focus offset, effects out of sync)

  Likely cause: Behavioral parameters (iris ramp, focus reference, effect timing) are defined in firmware; mixed versions across a rig produce visibly different behavior on identical DMX.

  Step-by-step fixGet the fix →

• Zoom Reset Error or Focus Reset Error

  Likely cause: Zoom and focus are motorized lens groups that calibrate travel at boot; a jam or a motor/optical-sensor that never reaches its reference position triggers the reset error.
