Kinetic LED Troubleshooting and Maintenance Guide
Kinetic LED faults should be diagnosed by layer instead of treating every symptom as a motor problem. Start by identifying whether the issue is mechanical movement, position feedback, communication, control timing, LED playback synchronization or an installation condition. Then test the smallest affected unit before changing the whole system.
This approach is especially important because the same visible symptom — for example, one module appearing out of position — can come from different causes.

Drift or Desynchronization Between Motion Units
If one or more units drift from the intended surface, first determine whether the target position is wrong or the unit is failing to reach a correct target. Check the affected module locally, verify position feedback, inspect the communication path and compare the behavior at lower speed. Avoid immediately rewriting the choreography; the content file may be correct while the motion or communication layer is not.
No Motion or No Position Feedback
Separate a command problem from a drive or feedback problem. Confirm power, controller status, communication and local motion response before replacing components. If a unit can be jogged locally but does not respond in the full sequence, the fault path is different from a unit that cannot move or report position at all.
Intermittent CAN Dropout
Intermittent communication faults can appear as random desynchronization rather than a permanent offline module. JYVISIONS project experience has included a tropical installation where condensation contributed to CAN connector oxidation. That lesson is useful because it changes the inspection path: environmental exposure and connector condition should be checked alongside software and controller logs.
This is a project lesson, not a universal failure rate.

High-Speed Noise or Structural Resonance
Noise can come from the actuator, guidance, mounting structure or the way repeated movement excites the supporting frame. JYVISIONS has encountered an indoor ceiling installation where structural resonance was part of the problem. If noise increases sharply at particular motion patterns or speeds, inspect the structure and mounting behavior rather than assuming the motor alone is responsible.
Exact dB claims should not be published without the underlying measurement evidence.
Video and Motion Do Not Line Up
When the LED content and physical movement appear out of phase, check the timing chain before changing mechanical settings. JYVISIONS has also seen a large real-time AE workflow where packet loss contributed to desynchronization. For larger systems, network design, traffic and redundancy therefore become part of motion reliability, not only IT housekeeping.

Limit Alarms and Stall Protection
A limit alarm should be treated as a motion-safety event, not simply cleared until the system moves again. Check whether the commanded trajectory is valid, whether the electronic limit is being reached correctly and whether there is a mechanical obstruction or abnormal resistance. Stall-current protection can help identify a drive problem, but it should not be described as general-purpose obstacle detection.
Preventive Maintenance
Routine maintenance should include visual inspection, fastener and structure checks, movement tests, connector and cable inspection, cleaning where required, lubrication according to the mechanism, and verification of limits and emergency-stop behavior. Keep appropriate spare parts for the installed configuration and record changes so future diagnosis has a known baseline.
JYVISIONS engineering records include lifecycle and maintenance observations from bench testing and field use, but cycle-life values and wear rates depend on operating conditions. Do not convert internal accelerated-aging results into an independent lifetime guarantee.
When to Return to Installation Checks
If a fault repeatedly returns after component replacement or software reset, revisit the installation conditions: structure, alignment, cable routing, grounding, movement clearance and environmental exposure. Installation and commissioning faults should first be checked against the kinetic LED installation guide.
For the commercial telescopic platform and current product architecture, see the JYVISIONS kinetic LED screen. If the fault belongs to a rotating mechanism, confirm the configuration on the 360° rotating LED screen page. If the fault belongs to the radial telescopic product, confirm the configuration on the kinetic LED sphere page.
