The chip features an on-chip 1.2V Low Dropout (LDO) regulator. This eliminates the need for an external step-down regulator to power the digital core.

Features an on-chip LDO regulator that generates the 1.2V core voltage.

: 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 .

To reverse-engineer or troubleshoot this T-CON board, you must look at the key component blocks that make up its architecture: 1. The Main T-CON Processor / ASIC Ksz80 Ob S4lv0.2 Datasheet

The KSZ8081 is built on Microchip’s (formerly Micrel) proprietary mixed-signal design. It is engineered to provide low power consumption and high robustness against electromagnetic interference (EMI). The "OB" designation typically refers to specific silicon revisions or packaging variants used in high-density PCB designs. Key Technical Specifications | Brand | Compatible TV Models | |

This article will serve as your complete guide to understanding the "KSZ80 OB S4LV0.2" T-Con board. We will cover what it is, how to identify it, the specific TV models that use it, the most common issues and failure symptoms, troubleshooting steps, and compatible alternative boards for repair.

: Available in both commercial (0°C to +70°C) and industrial (-40°C to +85°C) grades. 2. Pin Configuration and Core Interfaces

If you are looking for a key feature to highlight for this specific component, it would be its . In modern flat-panel displays, this board is the critical bridge that converts video signals from the main logic board into the specific timing and voltage signals required by the LCD panel to produce an image. Notable Characteristics

The KSZ8081RNB (often referred to in project BOMs as the KSZ80 OB S4LV0.2) is a single-supply 10Base-T/100Base-TX Ethernet physical layer transceiver. This specific hardware revision is widely used in industrial networking, automotive interfaces, and high-performance embedded systems. : If an internal short occurs within the

: 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

: Eliminates the need for external differential line termination resistors, reducing bill of materials (BOM) cost and conserving PCB space.

However, based on the prefix "Ksz80," we can identify this as a member of the .

The board is a compact, multi-layer Printed Circuit Board (PCB) with specific physical dimensions, mounting holes, and edge connector layouts that are proprietary to the LSY400HM02-A02 design. It receives power from the TV's power supply unit (PSU) and signals from the main board via flat flex cables (FFCs). It then drives the LCD panel through a series of delicate, bonded ribbon cables.
