This board is designed to convert AC power (100V-240V, 50/60Hz, 2.2A) into the necessary DC voltages for the TV's operation, including powering the LED backlight. It features clearly marked "HOT" and "COLD" sections, indicating the isolation between the primary (high voltage) and secondary (low voltage) sides for safety. The board includes various components such as transformers, capacitors, diodes, and integrated circuits, essential for power regulation and LED driving. The caution note on the board warns about the risk of fire and recommends replacing fuses with the same type and rating.
