Ksz80 Ob S4lv0.2 Datasheet ((link)) -
It solved .
The "LV" in the part number indicates low-voltage optimization. The KSZ80-OB-S4LV0.2 operates from a single 3.3V power supply while integrating an on-chip LDO regulator to generate the 1.2V core voltage. This reduces system bill-of-materials (BOM) costs by eliminating the need for an external core voltage regulator. Power Management Modes

: Requires professional handling via an LED Panel bonding machine (COF punching) for installation; it is not a plug-and-play component for casual DIY repair. Typical Signal Processing Features It solved
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.
It is important to note that while the T-Con board may fit physically, it is not interchangeable with the later model , which is intended for a different panel, the NS4S400DND01. No encryption handshake

Component-Level Repair Protocols
Integrates Low-Voltage Differential Signaling (LVDS) interfaces to translate video data from the main motherboard into column/row driver signals for the LCD matrix.
Voltage Gate Low. Generates a negative potential rail ensuring absolute, rapid shutoff of panel pixels to prevent ghosting or bleeding. 3. Circuit Failure Analysis: The "White Screen" Phenomenon
