Top — Lad711p Rev 10 Schematic

| Designator | Node | Expected Value (Standby) | |------------|-------------------|---------------------------| | TP1 | Bulk DC voltage | 320–380V DC | | TP2 | IC VCC | 12–18V DC | | TP3 | MOSFET Gate | 0V / 8–12V pulsed | | TP4 | Current sense (CS) | <1V peak (varies with load) |

In the context of "Rev 10" repairs on this chassis, the "Top View" is the most critical part of the schematic document because it highlights where the solder joints fail.

Note: The LAD711P is often confused with the standalone Horizontal Output Transistor (HOT), but in these chassis, it is typically part of the regulation circuit or the specific power transistor package used in the SMPS (Switched-Mode Power Supply) or the Horizontal Deflection. lad711p rev 10 schematic top

Let’s synthesize all the above into a step-by-step diagnostic flow using the lad711p rev 10 schematic top:

Title:
Analysis of the LAD711P Rev 10 Switching Mode Power Supply (SMPS) for Samsung LCD TVs | Designator | Node | Expected Value (Standby)

Abstract:
The LAD711P Rev 10 is a power supply unit (PSU) used in several Samsung 40–46″ LCD TV models. This paper dissects its schematic topology, including EMI filtering, standby power (5VSB), PFC (Power Factor Correction), main resonant converter (24V/12V), inverter backlight supply (if present), protection circuits, and feedback loops. Key ICs and failure points are identified.

In Sony CRT service manuals, revisions often indicate a running production change. For the LAD711P power supply circuit, Rev 10 (and surrounding revisions) typically addressed cold solder joints and thermal stress on the Horizontal Output Transistor (HOT) and the flyback pins. Note: The LAD711P is often confused with the

If you are looking at a schematic labeled Rev 10, pay special attention to the physical implementation of the circuit, not just the electrical connections.
