How to Find and Replace a Faulty Power Supply Board for Your LG 32LX2R TV
If you have a LG 32LX2R TV that is not turning on or showing signs of power failure, you may need to replace the power supply board. The power supply board is the component that converts the AC input voltage into the DC output voltage for the TV's circuits. A faulty power supply board can cause various problems, such as no power, no backlight, no sound, flickering screen, or distorted image.
In this article, we will show you how to find and replace a faulty power supply board for your LG 32LX2R TV. You will need a Phillips screwdriver, a flathead screwdriver, and a replacement power supply board. You can find a compatible power supply board online by searching for the model number YP2632T[^1^]. This is the original part number for the LG 32LX2R power supply board.
Step 1: Unplug the TV and Remove the Back Cover
Before you start, make sure to unplug the TV from the power outlet and disconnect any cables or devices attached to it. Then, lay the TV face down on a soft and flat surface, such as a carpet or a blanket. Be careful not to damage the screen or apply too much pressure on it.
Next, use a Phillips screwdriver to remove all the screws that secure the back cover of the TV. There should be about 20 screws in total. Keep them in a safe place for later reassembly. Then, use a flathead screwdriver to pry open the back cover from the edges. You may need to apply some force to release the clips that hold the cover in place. Once you have removed the back cover, you will see the internal components of the TV.
Step 2: Locate and Disconnect the Power Supply Board
The power supply board is located at the bottom right corner of the TV, as shown in the picture below. It is a rectangular metal board with several connectors and wires attached to it. To disconnect the power supply board, you will need to unplug all the connectors and wires from it. Be careful not to damage or pull on any wires or components.
The connectors and wires that you need to unplug are:
The AC input connector: This is a black connector with three wires (black, white, and green) that connects to the power cord socket.
The main board connector: This is a white connector with 24 pins that connects to the main board of the TV.
The backlight inverter connector: This is a white connector with 12 pins that connects to the backlight inverter board of the TV.
The speaker connectors: These are two black connectors with two wires each (red and black) that connect to the speakers of the TV.
The fan connector: This is a black connector with two wires (red and black) that connects to the fan of the TV.
After you have unplugged all the connectors and wires from the power supply board, you can remove it from the TV. There should be four screws that secure it to the metal frame of the TV. Use a Phillips screwdriver to remove them and then lift up the power supply board carefully.
Step 3: Install the New Power Supply Board
Now that you have removed the old power supply board, you can install the new one. Make sure that you have bought a compatible replacement power supply board with the model number YP2632T[^1^]. You can find it online by searching for \"LG 32LX2R power supply board\" or \"YP2632T schematic\".
To install the new power supply board, follow these steps:
Place the new power supply board on top of the metal frame of the TV and align it with the screw holes.
Use a Phillips screwdriver to secure it with four screws.
Plug in all the connectors and wires that you unplugged from the old power supply board. Make sure that they are firmly inserted and match their corresponding colors and pins.
Double-check that everything is connected correctly and securely.
