FAULT OVERVIEWUnderstand the symptom before replacing parts
A step-by-step troubleshooting guide that checks power, wiring, settings, and the affected component before parts are replaced.
English tutorial overview Complete English infographic with the six diagnostic or repair steps shown below.TOOLSPrepare before testing
!Safety noteUse the product label and wiring diagram as the final authority.
COMMON CAUSESCheck these areas first
- Power or voltage mismatch
- Loose, reversed, or damaged connection
- Controller, driver, or component failure
- Incorrect setting or incompatible device
STEP BY STEPDiagnostic procedure
Follow the sequence and change only one condition at a time.
01
Confirm power and device status
Make sure the light or controller is powered and the status indicator matches the product manual.
Step 01: Confirm power and device status — Cropped directly from this tutorial’s English main infographic.What to observeRecord the reading or behavior before changing the next variable.
02
Check phone and app permissions
Enable Bluetooth, local-network, nearby-device, microphone, or location permissions required by the feature.
Step 02: Check phone and app permissions — Cropped directly from this tutorial’s English main infographic.What to observeRecord the reading or behavior before changing the next variable.
03
Verify the correct network or connection method
Use 2.4 GHz Wi-Fi when required and connect from inside the app rather than the phone system settings.

04
Restart the light, controller, phone, and router
Power-cycle one component at a time and wait for it to reconnect before continuing.

05
Remove stale pairing information
Delete the device from the app or Bluetooth list and add it again using the documented reset sequence.

06
Test at close range with a second phone if available
A successful test with another phone helps separate device faults from account, app, or phone problems.

Expected result
The fault is isolated to a power source, connection, setting, controller, driver, or light section.
If the fault remains
Stop if there is overheating, odor, damaged insulation, repeated fuse failure, or exposed mains voltage.
