Power supply schematic for Samsung part BN44-00508B, supplied as a 553 KB PDF, revision B. BN44 numbering covers Samsung TV power boards. The diagram lets a technician follow standby and main rail generation, identify the PWM and PFC controllers and measure expected voltages when a set is dead or cycling on and off. It appears to be the same size as the 00509B document, so check the board label carefully to confirm the exact part number.
