LG / Sony T-Con Board

A faulty T-Con board typically presents as vertical lines, solarized or distorted colors, or a completely black screen while the backlight remains on. However, these symptoms can sometimes mimic panel or main board failures, so it is crucial to troubleshoot thoroughly before replacing the component.

Manufacturers often use multiple board revisions for the same television model depending on the production batch or panel type. Installing a board with a different part number, even if it physically fits, can cause permanent damage to your TV or result in an inverted or garbled picture.

This board is pulled from a television with a cracked or damaged panel, meaning the electronic components were fully functional before the screen break. We offer a 60-day warranty to ensure the board performs as expected upon installation.

Replacing a T-Con board involves opening the television chassis and handling delicate ribbon cables, which carries a risk of electrical shock or damaging the panel connectors. We recommend this repair only if you have prior experience working with television electronics.

First, double-check all ribbon cable connections to ensure they are seated firmly and locked in place, as loose connections are a common cause of persistent display issues. If the problem remains, verify that your original diagnosis was correct, as the issue may lie with the main board or the panel itself.
