The Samsung UA32EH400JR motherboard—typically labeled BN94‑14594E or BN41‑02711A—is the core mainboard for Samsung’s 32″ HD Ready LED TV, managing all vital functions including video/audio processing, signal input/output, firmware, and user interface. It supports 1366×768 resolution, powered by Samsung’s proprietary image engine, and delivers stereo sound (2×10 W). The board includes multiple connectivity options—2–3 HDMI ports, USB, composite/component video, RF antenna input, and optional VGA/optical audio—and interfaces internally with the T-Con board, power supply, IR sensor, and front-panel controls. As the “brains” of the TV, it stores settings and UI data; common issues like no display, HDMI failures, or boot problems are often resolved by replacing this plug-and-play OEM board
