Ksz80 Ob S4lv0.2 Datasheet Link

The part number "Ksz80 Ob S4lv0.2" appears to be a derivative of the Microchip KSZ80xx series of Single-Port 10/100 Ethernet Physical Layer Transceivers (PHYs). These devices are designed to interface standard MAC (Media Access Control) layers with twisted-pair copper media (RJ45). They are widely used in embedded systems, industrial automation, and consumer electronics due to their low power consumption and robust ESD protection.

The "S4lv0.2" suffix likely indicates:

KSZ80_0B_S4LV0.2 is a specific model of an LED TV Scaler PCB Board (also commonly referred to as a Timing Control

board). It is a critical component that bridges the main video processing board and the LCD panel, managing the timing signals and pixel data distribution required to display an image. Technical Overview

: Acting as the "translator" for the display panel, it receives LVDS signals (typically around 300 mV) from the main board and converts them into signals that drive the gate and source drivers of the LCD. Compatibility : This board is typically found in Ksz80 Ob S4lv0.2 Datasheet

(e.g., KDL-40R47A) and some Samsung-manufactured panels. It is highly specific to the PCB number; using a non-matching version can lead to failure. Power Supply : It features an onboard DC-DC converter that generates essential voltages such as AVDD (17V)

, VGH, and VGL from an input typically ranging between 5V and 12V. Common Failure Symptoms & Troubleshooting

If this board fails, the TV may power on with sound and backlights active, but display the following issues: White Screen

: Often caused by a shorted capacitor on the AVDD 17V line (specifically labeled as on this model). Distorted Images : Ghosting, solarization, or colored vertical lines.

: A completely black or unresponsive screen despite the backlight being lit. Repair & Installation Notes Professional Handling : Installation often requires a professional LED Panel bonding machine The part number "Ksz80 Ob S4lv0

(for COF punching) rather than standard soldering, making it difficult for DIY repairs. Diagnostic Tip

: If the screen issues (like lines) follow a "zoom" change on the remote, the problem is likely in the main video board. If they remain static, the KSZ80_0B_S4LV0.2 or the panel itself is the culprit. Purchasing

: You can find replacement units from specialized suppliers like Great Bharat Electronics

or secondary marketplaces, though they are often sold as pre-owned and without warranties due to their delicate installation nature. or a step-by-step testing guide for the AVDD line? AI responses may include mistakes. Learn more Buy Original LED TV Scaler PCB Board KSZ80-0B-S4LV0.2
