Overview

This listing provides a replacement T-CON (Timing Control) board for the Sharp LC-52D85UN 52-inch LCD television, identified by part number KF331 RUNTK4291TP 97B12T. The T-CON board is a critical component responsible for converting the video signal output from the TV's main board into the precise timing and voltage signals required to control individual pixels on the LCD panel. When this board fails, the result is often visible as horizontal or vertical lines, color banding, image distortion, or a completely blank screen despite the backlight still functioning.

This particular board is sold in used condition and has been tested to confirm excellent working order. For Sharp LC-52D85UN owners facing display issues that point to T-CON failure, replacing the board is a significantly more affordable repair compared to purchasing a new television. Installation involves opening the TV's rear panel, disconnecting the ribbon cables from the old T-CON board, and connecting the replacement. While the process is manageable for those with basic electronics repair experience, anyone unfamiliar with working inside televisions should consider having the replacement performed by a qualified technician.
