KSZ80 OB, S4LV0.2, and often secondary identifiers like LJ94-25257D LJ94-25482B
While a full "datasheet" in the semiconductor sense isn't public (as these are proprietary Sony/Samsung parts), repair technicians rely on the following technical characteristics: Specification Dual-channel LVDS (Low-Voltage Differential Signaling) Compatible Screen Size 40-inch LED/LCD Panels Major ICs ksz80 ob s4lv02 datasheet
The keyword does not refer to a standalone semiconductor component like a typical Ethernet transceiver. Instead, it is the identifying marking for a T-CON (Timing Controller) board typically used in Sony BRAVIA LCD televisions, most notably the Sony KDL-40R470A KSZ80 OB, S4LV0
The most common issue is a blown surface-mount fuse (often labeled F1) near the LVDS connector. If this fuse is open, the board receives no power, resulting in a black screen despite a working backlight. If you are searching for this board's datasheet

The term "KSZ80" in this context is part of the board’s silk-screen assembly number, and it should not be confused with the Microchip KSZ8081 series of Ethernet PHYs, which share a similar prefix but serve entirely different functions. Overview of the KSZ80 OB S4LV0.2 T-CON Board
