La garantía no se limita únicamente a la política de sustitución.
It also reflects the supplier’s confidence in long-term product stability.
What Warranty Usually Covers
Professional LED warranty typically includes:
- module replacement
- technical support
- receiving card support
- power supply replacement
depending on product category.
Why Different Products May Have Different Warranty Policies
Some high-end technologies such as:
- COB
- Micro LED
- ultra-fine pitch systems
may follow different replacement logic compared with traditional SMD products.
This is because repair complexity and component value are very different.
Why Maintenance Support Matters More Than Warranty Length
A long warranty is meaningless if technical support response is poor.
Professional support should include:
- troubleshooting guidance
- spare part availability
- remote technical assistance
- calibration support

Many customers focus heavily on warranty duration.
However, real after-sales quality depends more on:
- technical response speed
- spare part management
- engineering support capability
especially for international projects.
