Know before you buy
Check the physical label on your current T-Con board to ensure the part number 6871L-2966B or board number 6870C-0401C matches. While this board is designed for the LG 42L6200U, verifying the numbers on your original component is the most reliable way to ensure compatibility.
A failing T-Con board typically presents as vertical lines on the screen, a completely black display despite the TV being powered on, or distorted colors and solarized images. If your TV has sound but no picture, the T-Con board is a common culprit.
This specific board is engineered as a direct replacement for the LG 42L6200U. We do not recommend using it for other models unless the part numbers 6871L-2966B or 6870C-0401C are explicitly listed in your TV's service manual or on the existing board.
Yes, this T-Con board is backed by a 30-day warranty. This covers potential defects, providing you with time to install and test the component in your television.
Generally, you will only need a standard Phillips-head screwdriver to open the TV casing and remove the mounting screws for the board. Ensure the TV is unplugged and the internal capacitors have discharged before beginning the repair.
