Schematic of the Samsung BN44-00497A power supply unit, a 2.11 MB PDF. The BN44 prefix is Samsung's numbering for TV power boards, and the A suffix is the revision to match against the board label. The diagram supports tracing the primary side, PFC stage, standby supply and secondary outputs, measuring test points and finding the cause of no-power or shutdown faults. Any PDF reader opens it, and discharge the bulk capacitor before probing.
