Control Boards and Logic Boards for Televisions
TV control boards are essential components in modern televisions, responsible for managing signal input, processing, and output. These control boards ensure accurate image rendering and audio-video synchronization by coordinating communication between internal systems and handling user commands.
Common signs of a failing TV control board include no display, distorted images, signal loss, or unresponsiveness. The main board processes inputs and directs data to display and audio systems. The logic board manages communication for real-time image adjustments, while the timing control (T-Con) board controls pixel activation and synchronization for sharp visuals. TV control boards operate at 110V–240V and feature integrated processors for precise signal handling and compatibility. Regular inspection and timely replacement help maintain optimal TV performance.
At HnK Parts, we offer high-quality TV control boards and related components such as main boards, logic boards, and T-Con boards from top-selling brands like Samsung, LG, Philips, and Hisense at affordable prices.
