This replacement main board is designed for LG 55" LED TVs that use part number EBT64533403 (board model EAX67146203-1).

Other LG models using the same board number may also be compatible — verify board number before ordering.

Common Failure Symptoms

TV powers on but shows a blank or black screen
No HDMI or input detection despite correct source and connection
Freezing, reboot loops, or failure to boot fully
No audio or distorted sound even with correct input and settings
Random shutdowns or unexpected behavior after power on

Note: Issues may also stem from other components (power supply, panel, etc.) — proper diagnosis is recommended before ordering a replacement board.

Installation & Handling Notes

Disconnect the TV from power and wait several minutes before servicing to allow internal capacitors to discharge.
Use anti-static precautions when handling PCBs and internal components.
Ensure all ribbon cables and connectors are properly aligned and fully seated.
Avoid forcing any connectors or bending the board; handle with care to prevent damage.
