Model UA43RU7100 Samsung LED TV Motherboard

The Sony 40″ FHDW80P motherboard is an OEM-style main board designed for Sony’s 40-inch Full HD LED TVs in the FHDW80P series. It functions as the central control unit, managing video decoding, audio amplification, signal routing, firmware execution, and user interface presentation. Typically supporting 1920×1080 resolution, the board includes essential connectivity such as HDMI (2–4 ports), USB, component/composite AV, and RF antenna input, along with optical audio out and possibly a headphone jack, depending on the variant. Internally, it connects to the T‑Con board, power supply, IR sensor, and front-panel controls, ensuring synchronized operation of both the display and audio systems. This plug-and-play motherboard is the go-to replacement for common failures like blank screens, dead HDMI/USB ports, or unresponsive firmware, restoring full functionality to compatible Sony FHDW80P-series TVs.
