LG Smart TV Power Supply Assembly

The LG Television Power Supply Board (Part Number: EAY64548908) is an authentic original equipment manufacturer (OEM) replacement power supply unit (PSU) designed for LG televisions. Mounted directly inside the TV rear chassis, this Switched-Mode Power Supply (SMPS) board regulates AC household voltage into stable, precise DC power output required by the main motherboard, T-Con board, and LED backlight drivers.

Key Features

• Genuine OEM Precision: Engineered specifically for LG televisions to ensure exact factory fit, proper terminal alignment, and seamless performance.

• Integrated Power Regulation: Built with high-quality components and robust circuitry that regulates voltage and current output to extend appliance longevity.

• Long-Term Durability: Constructed with premium-grade materials designed to withstand continuous thermal stress and daily usage.

Benefits

• Solves common television power issues, such as a dead screen, blinking standby light, intermittent power shutoffs, or failure to power on.

• Direct replacement restores consistent operation and reliable performance without needing to replace the entire TV.

• Protects delicate processing electronics from voltage fluctuations and power spikes.

Applications

Designed specifically for select LG television models requiring part number EAY64548908.

What's Included

• 1 x Genuine LG Television Power Supply Board Assembly (EAY64548908)

Usage Instructions

1. DANGER: Unplug the TV from the wall outlet and allow high-voltage capacitors to discharge fully (15–30 minutes) before beginning work.

2. Place the TV face down on a soft, padded surface to prevent screen damage.

3. Unscrew and carefully remove the rear cabinet panel.

4. Unplug all wiring harness connectors from the old power supply board.

5. Unscrew the mounting screws securing the old board to the chassis.

6. Align the new LG EAY64548908 board, tighten mounting screws, reconnect wire harnesses, reattach the back cover, and test power.

Safety Instructions

• Disconnect main AC electrical power prior to opening the rear chassis panel. High-voltage components retain dangerous charges even when unplugged.

• Use anti-static protection and handle the PCB by its non-conductive edges to prevent Electrostatic Discharge (ESD) damage.

Care Instructions

• Keep TV ventilation grills clear of dust accumulation to maintain optimal heat dissipation across power board heat sinks.
