Ysus Schematic Diagram -

Check for shorted FETs (Drain to Source) in the sustain switching circuit.

Uses high-voltage FETs to toggle between Vscap V sub s and ground at high frequencies. Ysus Schematic Diagram

This report provides a technical analysis of the Y-Sustain (Y-Sus) board schematic diagram, a critical component in Plasma Display Panels (PDP). The Y-Sus board generates the high-voltage waveforms required to sustain plasma discharge. This document breaks down the major functional blocks—power management, energy recovery, and sustain switching—to facilitate diagnostics, component identification, and repair processes. 2.
