Vizio MT3151A05-3-XC-1 T-Con Board

The Vizio MT3151A05-3-XC-1 is a timing control (T-Con) board, a critical internal component responsible for translating processed video signals into the precise timing instructions that drive each pixel on the LCD panel. When a T-Con board fails, the result is often immediately visible: vertical or horizontal lines across the screen, washed-out or distorted colors, half the display going dark, or a completely garbled image — all while the TV's audio continues to function normally. This board is designed as a direct replacement for Vizio televisions that use the MT3151A05-3-XC-1 part number.

For TV owners facing these display symptoms, replacing the T-Con board is one of the most cost-effective repairs available. The process involves removing the television's back panel, carefully disconnecting the ribbon cables and power connector from the existing board, and installing the replacement. While not overly complex, it does require care — the ribbon cables connecting the T-Con board to the LCD panel are delicate and can be damaged if forced. Before purchasing, it is essential to verify that the part number on your current T-Con board matches MT3151A05-3-XC-1 exactly, as even visually similar boards from different Vizio models may not be interchangeable.
