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
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. ksz80 ob s4lv02 datasheet
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.

The server room of Lexicon Labs was freezing, smelling heavily of ozone and desperation. It was 3:00 AM, and the company's flagship prototype, the
(affectionately dubbed the "Salvo"), was refusing to communicate with the outside world.
At the center of the chaos sat Elena, the lead hardware engineer. Spread across her desk were schematics, logic analyzers, and a single, coffee-stained printout that held the answer to all her problems: the KSZ80 Ethernet Physical Layer Transceiver Datasheet. 🛠️ The Ghost in the Silicon Suggestion : If your component is Ethernet-related, search
The Salvo-02 was supposed to be a breakthrough in edge computing, but its network operations were completely dead. Elena had checked the power rails, verified the clock signals, and resoldered the RJ45 magjack. Everything looked perfect. Yet, the link light remained stubbornly dark.
"It has to be the bootstrap pins," she muttered, pulling the 100-page KSZ80 datasheet closer.
Datasheets were a unique kind of literature. They didn't have plots, but they had high stakes. One wrong interpretation of a timing diagram meant a $50,000 prototype became a paperweight. 📖 Deciphering the Code
Elena scanned the dense tables of register maps. She was looking for the hardware configuration straps—the physical pins that dictated how the chip behaved at the exact millisecond power was applied. Page 24: Pin 14 (RXD1/PHYAD1). Page 25: Pin 15 (RXD0/PHYAD0).
Her eyes narrowed as she read the fine print at the bottom of the electrical characteristics table:
"Note 4: If the S4-LVO host controller drives the RXD lines high during system reset, the KSZ80 will override the default PHY address. This will cause communication failure on the MIIM (Management Interface) bus." "That's it," she whispered.
The S4-LVO processor was inadvertently pulling the line high during boot. The Ethernet chip was waking up at the wrong address, effectively making it deaf to the processor's commands. It wasn't broken; they were just shouting into a void where no one was listening. 💡 The 4:00 AM Miracle
Elena grabbed her soldering iron. With a steady hand, she wired a tiny pull-down resistor to the trace, forcing the pin to read a logical '0' during the boot sequence.
She plugged in the power supply. The cooling fans roared to life. She hooked up the Ethernet cable and held her breath.
On her monitor, the terminal window scrolled rapidly:[OK] S4-LVO Booting...[OK] Initializing KSZ80 PHY...[OK] Network link established at 100 Mbps.
