Small 84.1 KB PDF schematic for the BN44-00192B board, a code from Samsung's BN44 power supply numbering used for TV and monitor PSUs. No model or panel information is carried in the name. A diagram of this kind lets a technician follow the standby and main converter, find the fuse, bridge, switching MOSFET and feedback loop, and compare measured voltages with expected values. The B suffix is a revision letter, so check that it matches the one on the board sticker; a different suffix may change components. Given its small size, the file may cover only part of the circuit.
