The Samsung UA32FH4003R motherboard (commonly identified as BN41-02156A or BN94-07223B) is the main electronic circuit board that controls all core functions of the Samsung 32-inch HD Ready LED TV. It manages video processing, audio output, input/output operations, and user interface control. Powered by the HyperReal Engine, it supports a 1366×768 resolution and provides clear, vibrant visuals with enhanced color and motion handling. The board includes essential connectivity options such as 2 HDMI ports, 1 USB port, component/composite input, RF antenna input, and headphone output, enabling seamless integration with set-top boxes, USB drives, and gaming consoles. It also supports Dolby Digital Plus and DTS Studio Sound technologies for a rich audio experience. The motherboard interfaces internally with the T-Con board, power supply, IR sensor, and speakers, ensuring synchronized operation of all hardware. As the central control unit of the TV, it plays a critical role in delivering both performance and reliability, and it is often replaced to resolve common faults like no display, signal failure, or non-responsive HDMI/USB ports.
