April 28, 2026 Subject: Y-Sustain (Y-Sus) Circuit Analysis and Troubleshooting Schematic Report Prepared For: Technical Engineering/Repair Team 1. Executive Summary Ysus Schematic Diagram

What is the of the TV or the Y-Sus board (e.g., EBRXXXXXX)? Focus on the Y-Sus board (e

The Y-Sus board is highly susceptible to component fatigue, particularly within the switching circuits. The schematic analysis points to specific FETs and recovery circuits as primary failure points. Efficient repair requires checking these components for shorts and verifying that the ERC is functioning correctly to prevent high-voltage failure. 7. Recommendations The Y-Sus board is highly susceptible to component

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

The schematic highlights essential TP (Test Points) for measuring Vscap V sub s Vgcap V sub g (gate voltage), and waveforms using an oscilloscope. 5. Troubleshooting Based on Schematic
