Ksz80 Ob S4lv0.2 Datasheet <Android EXTENDED>

The KSZ80-0B-S4LV0.2 is not a standalone integrated circuit datasheet but rather a specific Scaler PCB Board (also known as a Panel Scaler PCB or T-Con interface board) commonly found in Sony LED/LCD TVs, such as the Sony KDL-40R473A KDL-40R450A Technical Overview

This board acts as the critical bridge between the TV's main logic board and the actual LCD panel. It processes image enhancement signals and distributes the necessary voltages for the display to function. Primary Function: Scaler boards like the KSZ80-0B-S4LV0.2

manage the timing and driving of the pixels on the LCD glass.

Voltage Requirements: It typically operates on a 12V VCC input and generates secondary voltages for the panel, including: 3.3V: Logic power. VGH / VGL: Gate high/low voltages for pixel switching. AVDD: Analog supply for the source driver. Common Issues and Troubleshooting

In the 40-inch Sony LED series, this board is frequently associated with "No Display" or "Blank Screen" symptoms where the backlight remains functional.

Protection Mode: If an internal short occurs within the gate signals of the glass panel, the DC-DC IC on the KSZ80 board may enter protection mode, causing VGH, VGL, and AVD voltages to disappear.

Temporary Repair Method: Technicians often use a "track cutting" method on the scaler PCB to isolate shorted gate signals (such as CKV1, CKV2, or CKB lines) to restore the picture, though this is often a temporary fix.

Availability: These boards are often sourced from specialized electronics retailers as pre-owned parts, as they are typically tied to specific panel models and are not sold as generic components. Buy Original LED TV Scaler PCB Board KSZ80-0B-S4LV0.2

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

(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

T-CON Board Repair Techniques Guide | PDF | Liquid Crystal Display

The KSZ80-0B-S4LV0.2 is a specific Scaler PCB (also known as a T-CON board or Panel Scaler) used in LED and LCD televisions, most notably within Sony Bravia models like the KDL-40R470A.

Unlike a standalone integrated circuit (IC) datasheet, this guide covers the technical specifications and architecture of the entire board assembly. 1. Board Overview & Identification

This board serves as the bridge between the TV's main motherboard and the LCD panel, processing image signals (LVDS) to ensure correct timing and pixel data for the display.

PCB Number: KSZ80-0B-S4LV0.2 (also referred to as KSZ80_0B_S4LV0.2). Common Applications: Sony LED/LCD TVs (e.g., KDL-40R470A).

Core Component: Often paired with high-performance picture quality enhancement ICs like the Sony CXD4732R, which handles post-scaling for Full-HD and WXGA signals. 2. Key Technical Features

Signal Processing: Enhances picture quality for progressive scan signals after they have been scaled by the main system.

Interface: Primarily utilizes LVDS (Low-Voltage Differential Signaling) to transmit high-speed digital data to the panel.

Power Management: Includes onboard voltage regulators (LDOs) to supply stable power to the scaling IC and the LCD driver circuits.

Compatibility: Strictly tied to specific panel models; replacing this board with a different version (even if it looks similar) can result in distorted images or no display. 3. Integrated Components (KSZ80 Series) An obfuscated or scrambled part number (common in

While this is a board-level part, "KSZ80" often appears in Microchip/Micrel Ethernet PHY naming (like the KSZ8081). However, in the context of TV repair, the board itself is the functional unit. Relevant internal architectures for this series include:

On-chip Termination: Reduces board cost and improves signal integrity for differential pairs.

Diagnostics: Often supports features like LinkMD TDR-based cable diagnostics for identifying faults in the internal ribbon cables. 4. Practical Repair & Maintenance

Testing: Boards are typically tested under "real TV simulation" conditions by technicians to verify output to the panel. Common Fault Symptoms: No image but backlights are on.

Solarized or distorted colors (often caused by the gamma IC or main scaler chip). Vertical lines or "ghosting" across the entire screen.

Sourcing: Available through specialized parts retailers like Great Bharat Spares or Harry Electronics. KSZ8081MNX/RNB Data Sheet - Microchip Technology
