Provide actionable information for repairing common Y-Sus failures (e.g., no picture, vertical lines, clicking sounds). 3. Functional Blocks of Y-Sus Schematic
The scan driver connector receives timing signals from the main board/logic board, while the top of the board receives high-voltage sustain signals. Ysus Schematic Diagram
Are you seeing a (like a blinking LED) or just a black screen? typically found in LG
The schematic often reveals that failure clusters around the switching MOSFETs (e.g., ) due to overheating. Ysus Schematic Diagram
Focus on the Y-Sus board (e.g., typically found in LG, Samsung, Panasonic PDPs).
Check for shorted FETs (Drain to Source) in the sustain switching circuit.
