Samsung power supply unit schematic for board BN44-00213A, supplied as a 639 KB PDF. The BN44 prefix marks Samsung PSU modules used in flat-panel TVs and monitors, and the name confirms this one is a PSU. With it a repairer can follow the mains input, bridge rectifier, PFC section and secondary rails, and identify the standby supply that is often the first stage to fail. Check the sticker part number and revision on the actual board, since neighbouring BN44 codes use different layouts and component values. Open it with any standard PDF reader.
