LG TV Main Boards

LG TV main boards are the key to a functioning LG display. Commonly referred to as a motherboard, this piece of hardware controls nearly all electrical functions within the TV. Whether you have an LCD TV, an HD TV, or a smart TV, a primary circuit board can be found within the screen.

What is an LG TV main board?

TV main boards are a type of circuit board, also known as a circuit card, that houses the primary computer controls for an LG display. All other circuit boards and components will be connected in some way to this main unit. Like many printed circuits, TV circuit cards are comprised of a series of conductive metallic pathways to connect various circuits on the unit itself. The circuits are usually printed on a piece of synthetic material and are commonly referred to as printed circuit boards (PCBs). Since all components and circuit cards present within the TV are in some way connected to this primary controller circuit, an LG television circuit card can be thought of as a hub for all other activities within the device.

How do you choose and install a new main board?

Performing a replacement repair for your smart, full HD, or LCD TV can vary in difficulty. This is dependent on the model of the LG product you are fixing. Some repairs may only require working knowledge of display hardware, a screwdriver, and a socket wrench. More complex repairs may require advanced electrical knowledge or soldering. Carefully research the process for replacing your board before attempting a repair to get the best results. Special care needs to be taken when attempting to replace parts on an LED TV and a smart TV.

  • It's important to select the correct part when replacing the main board in your TV. Motherboard selection will usually be model specific, so ensure you have the correct model name for your TV before purchasing a part. You can verify the model of the part itself by inspecting the motherboard in your TV.
  • Access to the TV's motherboard varies by model, but the device itself can usually be exposed by unscrewing a panel in the rear of the TV. The exact location of the motherboard may vary, so be careful when accessing this section of your TV. Once located, identify the model number to get the exact match for your LG product.
  • Old circuit cards can be tested using a multimeter electrical tester to ascertain whether or not they are still functioning. New motherboards should also be tested to ensure they are in working order before attempting a repair.
