Schematic PDF, 187 KB, for Samsung-numbered power supply boards BN44-00632A and BN44-00633A, listed with the codes L46F2P and L55F2P, which suggest 46-inch and 55-inch variants. The BN44 prefix is Samsung's part numbering for TV power boards. Use the diagram to trace standby and main rails, check the PFC stage and locate the components behind a no-power or clicking fault. Verify the exact BN44 code printed on the board, since the two versions differ.
