LG LED TV Power Supply Board

This LG LED TV Power Supply Board is an original replacement SMPS board designed to supply stable and regulated power to the main board, T-Con board, and LED backlight system of LG LED televisions. It converts AC input (100–240V) into multiple DC output voltages required for proper TV operation.

The board includes high-quality transformers, filter capacitors, rectifier diodes, power MOSFETs, coils, and heat sinks for efficient and safe performance.

Main Functions:

• Converts AC power to a regulated DC output

• Supplies power to the Main Board and T-Con Board

• Drives the LED Backlight circuit.

• Provides standby voltage

• Over-voltage and short-circuit protection.

Input Specification:

• AC Input: 100–240V

• Frequency: 50/60Hz

Common Output Voltages:

• 3.5V / 5V (Standby)

• 12V / 24V (Main Supply)

• LED Backlight Voltage (Model dependent)
