Proper periodic cleaning
Dust and moisture are the biggest enemies of LED screens:
Use a soft cloth or a gentle vacuum cleaner
Avoid using corrosive chemicals
Never spray water directly onto the screen surface.

Check power supply and voltage protection
Unstable power supply can cause fire, especially during start-up or sudden power outage. Please:
Use voltage stabilizer or UPS
Periodic inspection of electrical system
