The motherboard functions as the central processing unit for your television. Once correctly installed, it enables all standard TV operations, including power management, signal processing from various inputs (HDMI, USB, etc.), and output to the display panel and speakers.

• Dust Removal: Periodically clean the interior of your TV to prevent dust buildup on the motherboard and other components. Use compressed air or a soft brush. Ensure the TV is unplugged before cleaning.
• Ventilation: Ensure the TV's ventilation openings are not blocked to allow for proper airflow and heat dissipation.
• Avoid Liquids: Keep liquids away from the television to prevent spills that could damage internal electronics.
