Circuit diagram in PDF format for the Samsung BN44-00198A power supply board. Only the part number appears in the name, so the specific set it was fitted to is not given. The BN44 code family covers Samsung TV and monitor power modules, and a schematic like this helps when measuring standby voltage, checking the start-up circuit of the PWM controller, or hunting a short on the secondary outputs. Confirm the code and letter suffix printed on the PCB before relying on part values. The document is 240 KB and opens in any PDF viewer on desktop or mobile.
