The keyword "KSZ80 OB S4LV0.2" 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

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 ksz80 ob s4lv02 datasheet

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. Primary Application: Used extensively in the Sony KDL-40R470A and related 40-inch LED/LCD models.

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

Role in TV Repair: This board is the first suspect when a TV has sound but no picture, or shows vertical/horizontal lines and distorted colors. Technical Specifications and Connectivity

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 Input Interface Dual-channel LVDS (Low-Voltage Differential Signaling) Compatible Screen Size 40-inch LED/LCD Panels Major ICs

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

Surface-mount LEDs (on some revisions) to indicate power-good status Troubleshooting Common Faults

If you are searching for this board's datasheet to repair a faulty television, look for these common failure points:

SMD Fuse Failure: 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.

Gamma IC Failure: 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.

VGH/VGL Voltage Issues: 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

Because these boards are specific to certain TV models, they are typically found as salvaged or refurbished parts rather than new retail items. You can find listings for this specific board on eBay or Kupindo.

KSZ80-0B-S4LV0.2 isn't just a string of characters; it is a critical LED/LCD TV Scaler PCB Board

. While "KSZ80" often refers to a family of high-performance Ethernet PHY transceivers manufactured by Microchip Technology , in the context of the Key features

revision, it represents the "brain" of a television's display panel. The Story of a TV’s Revival

Imagine a high-definition LED TV that suddenly goes dark. The backlight might be on, but the images—the vibrant colors of a nature documentary or the sharp lines of a video game—have vanished. Inside, the culprit is often a failed scaler board. The Diagnosis : A technician opens the chassis and identifies the KSZ80-0B-S4LV0.2 PCB

. This specific board is responsible for taking incoming video signals and "scaling" them to fit the exact resolution of the LCD panel. The Component : The board likely utilizes a KSZ80 series chip , such as the Microchip KSZ8081 , which manages data transmission at 100Mbps speeds The Repair : Finding an KSZ80_0B_S4LV0.2 board is essential for maintaining the original display quality

. Because these parts are often pre-owned and salvaged from "screen-damaged" units, they undergo rigorous testing by certified technicians to ensure they can still process signals perfectly. The Result : Once swapped, the tiny transceivers and controllers begin their work again. Data flows through the RMII or MII interfaces , and the TV "wakes up," returning to its former glory.
