Ksz80 Ob S4lv0.2 Datasheet [95% POPULAR]

This component is not unique to a single manufacturer. Based on repair forum reports, the "KSZ80 OB S4LV0.2" T-Con board is most commonly found in LCD televisions from major brands, including:

Reflow or replace the T-CON processor if thermal stress is suspected. 🛒 Finding Replacement Parts

Analog Supply Voltage. Powers the internal source driver operational amplifiers responsible for column sub-pixel grayscale levels. +25.0 V to +32.0 V

The identifier "" refers specifically to a Panel Scaler PCB Board used in LED TVs. While parts of this code resemble Microchip's KSZ80 series of Ethernet transceivers (like the KSZ8081 or KSZ8091), in this specific alphanumeric format, it represents the model or version of a display controller board rather than a single IC.

: Keep the positive and negative traces within each pair matched in length to within 10 mils (0.25 mm) to avoid phase skew.

The most critical semiconductor asset on this board is the . It functions as a step-up DC-DC switching regulator and multi-rail charge pump controller responsible for generating four primary display rail configurations: Voltage Rail Label Nominal Expected Value Circuit Functionality VIN / VCC

In both cases, this board works in conjunction with a 40-inch LCD panel. The Sony and JVC TVs likely use a similar panel assembly. Specifically, the Sony KDL-40R473A model uses an , which is paired with this T-Con board. This component is not unique to a single manufacturer

Power off the television and disconnect it from the AC outlet. Set your multimeter to .

As a T-Con board, the "KSZ80 OB S4LV0.2" translates raw video signals into specific drive signals for the LCD's individual pixels. Based on the LCD panel it controls, its expected technical capabilities include:

The physical form factor of the component, such as SMD (Surface Mount Device) or THT (Through-Hole Technology), which affects how it's mounted on a PCB.

The scalar board acts as the structural intermediary between the main television logic motherboard and the physical liquid crystal glass panel. It receives raw low-voltage differential signaling (LVDS) video data, processes spatial scaling, and generates the massive matrix drive voltages required to toggle individual liquid crystal sub-pixels.
