Ds-80249 -p Rev 1.2 Schematic ((new))

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).

• Dimensional drawings showing the physical layout and mounting points of the component or PCB.

B. The JTAG / programming header

• Symptom: Board occasionally resets or fails to boot.
• Schematic check: Rev 1.2 often ties the "TRST" pin to ground via a 0-ohm resistor. If that resistor is missing (or marked "DNP" in the schematic), the debug interface floats, causing erratic behavior.

Firmware Dumps: Verified DUMP files for Rev 1.2 are available on technician forums like Remont-aud for system flashing via programmers like the TL866CS. ds-80249 -p rev 1.2 schematic

Mounting: Four M3 mounting holes with chassis ground connection.

Manufacturer Portal: If this is part of an evaluation kit (such as those from NXP, STMicroelectronics, or Texas Instruments), the schematic is usually found in the "Design Resources" or "Tools & Software" section of the specific product page [4]. The DS-80249-P (often referred to as DS-80249-P rev 1
