troubleshooting
1. What should I do if some areas of the EL cold light sheet are not lit?
Cause: Poor electrode contact, line break, insufficient driving voltage.
Solution: Check the electrode connection point, replace the inverter to test, and avoid excessive bending.
2. Flashing problems occur during use of EL cold light
Cause: Unstable driving voltage, mismatched frequency or poor line contact.
Solution: Replace the stable power supply to ensure that the inverter frequency matches the product (such as 500-600Hz).
