LG TV T-Con Boards – Timing Control Boards for LG TVs
LG televisions use multiple internal boards and cables to process picture, sound, power and display functions. The T-Con Board, also known as Timing Control Board, is one of the most important parts in the display section of a LG TV.
The T-Con board receives video data from the motherboard through the LVDS cable and converts it into panel-specific timing signals. These signals are then sent to the display panel through FFC ribbon cables or panel connections. If the T-Con board is faulty, the TV may power on normally but still show display-related problems.
