This board is the primary control center for your television.

However, we recommend troubleshooting power supply issues first to confirm the main board is the actual source of the problem.

This board is specifically designed for the LG 55LH5750UB BUSCLOR model. Please verify your TV's model number on the back panel sticker before purchasing to ensure a perfect match.

Installing a main board requires opening the television chassis and handling delicate internal electronics. If you are not comfortable working with ribbon cables and internal power connections, we strongly recommend having a professional technician perform the installation to avoid damaging the board or your TV.
