The "KSZ80" identifier maps directly to the Microchip Technology KSZ8041 Single-Supply Fast Ethernet Transceiver . On connected panel assemblies, this IC handles system-level telemetry and synchronous commands. Specification 10BASE-T / 100BASE-TX Fast Ethernet Supply Voltage 3.3V Nominal (3.135V to 3.465V Tolerance Range) Interface Options Media Independent Interface (MII) & Reduced MII (RMII) Package Style 32-Pin Lead-Free QFN / MLF Special Mechanics HP Auto MDI/MDI-X for automatic cable crossover correction
Desolder the shorted CD8 MLCC and clean the footprint. Replace it with an identically spec'd high-voltage surface-mount capacitor (typically rated at 25V or 50V operational tolerances) to safely restore the +17V AVDD line and recover the display. Panel Gate Driver Faults Ksz80 Ob S4lv0.2 Datasheet
