The DS-80249-P (often referred to as DS-80249-P rev 1.2) is a common power supply board found in Samsung LCD monitors (e.g., SyncMaster 943NW). It is a combined Power and Inverter board that handles AC-to-DC conversion and drives the CCFL (Cold Cathode Fluorescent Lamp) backlight. Key Technical Specifications (Full Features) Input Voltage: Standard AC 100V–240V (~50/60Hz).
Output Voltages: Typical outputs include +5V (for logic board power) and +15V (for the inverter section).
Inverter Section: Integrated dual-transformer design to drive two or four CCFL tubes.
Safety Features: Includes Over-Voltage Protection (OVP) and Short-Circuit Protection (SCP). Main Components:
PWM Controller: Often uses an FAN7601 or FAN7382 (depending on exact sub-revision).
MOSFETs: Typically utilizes components like FDD8447L or similar for switching.
Transformers: High-voltage step-up transformers (e.g., TM-0917) for the CCFL lamps. Schematic and Repair Resources
The schematic for this board is usually bundled within the Samsung BN44-00249C or PWI1902SS service documents.
Schematic Download: You can find the detailed circuit diagram and repair information for this power supply model at Elektrotanya. Common Failure Points:
Leaking/Bulging Capacitors: Often the 1000uF or 820uF output filter caps fail, leading to "no power" or "flashing LED" symptoms.
Bad CCFL Inverter Transformers: Open windings in the high-voltage transformers will trigger the "two seconds to black" protection mode.
