LG LED TVs are known for their superior picture quality, excellent sound output, and advanced technology. However, like any other electronic device, certain parts of your LG TV may start malfunctioning over time. Instead of discarding your TV and buying a new one, you can repair your LG TV by replacing the faulty parts. This is not only cost-effective but also helps extend the lifespan of your TV.

If you're experiencing no power, black screen, distorted images, or sound issues, you may only need to replace a particular component in your TV. At Great Bharat Electronics, you can easily find and buy genuine LG TV parts such as motherboards, power supply boards, T-Con boards, backlight strips, inverter boards, and much more.

In this detailed guide, we’ll walk you through the most commonly used LG TV parts, their functions, signs of failure, and how replacing them can restore your TV to its full performance.

✅ 1. LG TV Motherboard (Main Board)

The motherboard, also called the mainboard, is the brain of your LG TV. It processes video, audio, and input signals and ensures smooth operation. The motherboard also handles HDMI, USB, and Wi-Fi connectivity (for smart TVs).

Main Functions of an LG TV Motherboard:

Controls all audio and video signals.
Manages input and output connections like HDMI, USB, AV, etc..
Ensures smooth wireless connectivity in smart TVs.
Distributes power to other components.

Signs of a Faulty Motherboard:

The TV doesn’t turn on.
No display, but sound is working.
HDMI, USB, or AV ports are unresponsive.
TV screen freezes or lags while operating.

✅ Solution:

If your LG TV has any of these problems, it's likely a motherboard failure. You can easily replace it without replacing the entire TV.

✅ 2. LG TV Power Supply Board

The power supply board is responsible for converting AC power (from your wall socket) to DC power, which powers all the components inside your LG TV. If the power supply board is faulty, your TV may not turn on, shut off randomly, or have voltage fluctuations.

Main Functions of a Power Supply Board:

Converts AC power to DC power.
Distributes electricity to the motherboard, display, and backlight.
Protects the TV from power surges.

Signs of a Faulty Power Supply Board:

TV not turning on despite being plugged in.
Sudden power off or random restarts.
Flickering screen or low brightness.
Burning smell or buzzing sound from the back.

✅ Solution:

If your LG TV refuses to turn on or has power-related issues, you likely need a new power supply board.

✅ 3. LG TV T-Con Board (Timing Control Board)

The T-Con board (Timing Control Board) is responsible for controlling the picture display on your screen. It regulates image processing, sharpness, and clarity. If your TV screen shows distorted images, horizontal lines, or no picture, the T-Con board may be faulty.

Main Functions of a T-Con Board:

Converts image signals into clear images.
Regulates color, sharpness, and display.
Handles horizontal and vertical synchronization.

Signs of a Faulty T-Con Board:

Black screen with sound.
Half screen display.
Vertical or horizontal lines.
Distorted images or double pictures.

A malfunctioning T-Con board can easily be replaced without affecting any other component.

✅ 4. LG TV LED Backlight Strips

The backlight strips are what provide illumination to your TV screen. Without backlights, your screen will appear completely dark, even though you can still hear sound.

Main Functions of Backlight Strips:

Provide lighting behind the display panel.
Enhance brightness, color accuracy, and picture clarity.
Allow clear visuals during day and night.

Signs of Faulty Backlight Strips:

Black screen despite the TV being on.
Uneven brightness across the screen.
Flickering or dim screen.
Bright patches or dead zones.

✅ Solution:

If your screen has gone completely dark or has uneven brightness, replacing the backlight strips will instantly resolve the problem.

✅ 5. LG TV Inverter Board

The inverter board provides power to the LED backlight strips. If your inverter board fails, the backlight will not receive power, resulting in a dark or flickering screen.

Main Functions of an Inverter Board:

Supplies power to backlight strips.
Controls the brightness of the display.
Ensures power efficiency.

Signs of a Faulty Inverter Board:

Black screen but sound working.
Flickering display.
Uneven screen brightness.

✅ Solution:

If your TV has no display or the screen remains dim, replacing the inverter board will solve the problem.
