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.
The PHY enters a ultra-low-power mode when no cable is attached. It periodically sends out pulses to detect a link partner.
If you are looking for a datasheet with the exact filename or header "KSZ8081 Ob S4lv0.2," you are likely looking at a specific silicon revision or an internal revision code for the standard KSZ8081 Single-Chip 10/100 Ethernet Physical Layer Transceiver.
Since there is no "datasheet" in the traditional sense, you must rely on technical service manuals for the TV models that use it:
Are you designing for a or an automotive environment ? Ksz80 Ob S4lv0.2 Datasheet
Used primarily in LED and LCD TV repair and assembly.
Uses Time Domain Reflectometry (TDR) to analyze the cable status.
Manages software reset, loopback mode selection, speed selection (10 vs 100 Mbps), auto-negotiation enable, and power-down modes.

She reached into her coat and placed a small, unmarked metal case on the desk. It hummed faintly.
The transmit and receive center taps on the PHY side must be decoupled with 0.1µF capacitors to ground.
The T-Con board acts as the critical bridge between the television's main system board (motherboard) and the physical TFT-LCD glass panel assembly.
Due to the sensitivity of scaler boards, they are often shipped in anti-static bags with multi-layer shock-absorbent foam. Related Component Information (KSZ Series)
