A 1.47 MB PDF schematic for the BN44-00605A power supply board, also referenced as PSLF770S05A in the name. BN44 is the Samsung part-number series for TV power boards. With this diagram a technician can follow the mains input, PFC, standby converter and LED or main outputs, measure expected voltages and locate shorted MOSFETs or failed capacitors. Open it with any PDF reader and confirm both codes on the PCB label before trusting component values.
