Ksz80 Ob S4lv02 Datasheet Link -

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

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

The T-CON board acts as the "brain" of the display panel. It receives video data from the television's main logic board (via LVDS cables) and translates it into the specific timing signals required by the Source and Gate drivers to activate the individual pixels on the LCD. Used extensively in the Sony KDL-40R470A and related 40-inch LED/LCD models. ksz80 ob s4lv02 datasheet

Typically includes a Samsung or Sony proprietary timing controller chip 12V (VCC), VGH, VGL, and AVDD (Analog Supply) Status Indicators

If you are searching for this board's datasheet to repair a faulty television, look for these common failure points: The keyword does not refer to a standalone

KSZ80 OB, S4LV0.2, and often secondary identifiers like LJ94-25257D LJ94-25482B

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. Used extensively in the Sony KDL-40R470A and related

Using a multimeter, technicians check for VGH (typically +20V to +30V) and VGL (typically -5V to -10V). If these are missing, the screen will likely remain blank or display a slowly fading image. Where to Source Parts

Distorted or "washed out" colors are often caused by a failing Gamma IC (AS15-F or similar) which manages the reference voltages for color accuracy.
