LG T-Con Board

A faulty T-Con board typically presents as vertical lines, solarized or distorted colors, or a completely black screen while the audio still works. If your TV has power and sound but the picture is corrupted, this component is a very likely culprit.

Yes. This board is compatible with part numbers 6870C-0028E and 6871L-0598A. Always verify the number printed directly on your existing board to ensure an exact match, as manufacturers sometimes use different revisions for the same TV model.

If you are comfortable opening the back of your television and handling delicate ribbon cables, this is a straightforward repair. However, it does require basic technical knowledge and the ability to work safely around internal electronic components.

Likely not. If your TV has no power, no standby light, and no sound, the issue is usually with the power supply board rather than the T-Con board. The T-Con board specifically handles the processing of the video signal to the display panel.

It is best to stick to the compatible model listed, which is the 42LP1D. While some boards share part numbers across different models, T-Con boards are often programmed specifically for the panel type and resolution of a particular TV, so compatibility outside the specified model is not guaranteed.
