The LG Television Main Board (Part Number: EBT66698601) is the main control motherboard responsible for your TV’s key functions including power control, picture processing, sound output, HDMI/input signal handling, and overall system communication.

If your LG TV is facing issues like no picture, no sound, HDMI not working, stuck on logo, or random restarting, replacing the main board is one of the most effective repairs to restore full functionality.

This board is designed to be a direct replacement for compatible LG television models and helps bring your TV back to factory-level performance.
