Understanding the DS-80249-P Rev 1.2 Mainboard: A Repair & Modification Guide
If you are a CCTV technician or a hobbyist, you have likely encountered the DS-80249-P Rev 1.2
. This specific mainboard is the "heart" of several popular DVR (Digital Video Recorder) models, most notably those from and its rebranded versions like Commonly found in units like the DS-7208HGHI-F1
, this board is known for its durability but can occasionally require troubleshooting for power failures, password resets, or firmware issues. Technical Overview: DS-80249-P Rev 1.2 DS-80249-P Rev 1.2
is a 8-channel DVR system board designed to handle both analog (HD-TVI) and IP camera inputs. Board Variants: You may see versions labeled (standard) and DS-80249_P
. The "P" often indicates specific power or port variations, but the core schematic remains largely consistent across Rev 1.2 and later revisions like 2.1. Key Components: Power Circuit: Typically driven by a 12V DC input. Storage Interface: Supports standard SATA HDDs. Connectivity:
Features VGA, HDMI, and USB ports, along with an RJ45 Ethernet interface. Common Troubleshooting Steps 1. Power Issues (DVR Not Turning On)
If your board isn't powering up, the issue is often related to the external power adapter or internal capacitors. Check the Adapter:
Ensure you are using the manufacturer-recommended 12V / 1.5A adapter. Visual Inspection:
Look for "bloated" capacitors or burn marks near the DC input jack. 2. Hard Reset & Password Recovery Report: DS-80249-P Rev 1
Forgotten passwords are the most frequent reason people search for this schematic.
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.
