8. Troubleshooting
If you encounter any issues with your LED strip lights, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on | No power supply, incorrect voltage, loose connection, damaged strip. | Check power supply connection and ensure it's DC24V. Verify all connectors are secure. Inspect the strip for visible damage. |
| Uneven brightness or dark spots | Damaged section of the strip, insufficient power for length, poor connection. | Ensure the power supply wattage is adequate for the total length. Check connections for continuity. If a section is damaged, it may need replacement. |
| Adhesive not holding | Surface not clean, uneven surface, excessive weight on strip. | Clean the surface thoroughly before reapplication. Use additional clips or stronger adhesive if needed for heavy-duty applications. |
| Lights flicker | Unstable power supply, loose connection, incompatible dimmer. | Ensure power supply is stable. Check all connections. If using a dimmer, ensure it is compatible with DC24V LED strips. |
If the problem persists after trying these solutions, please contact PAUTIX customer support.
