When you conduct on a component level repair for the Power Supply CBA for any models within this service manual,
make sure to refer the right Block Diagram/Schematic Diagram/CBA and Parts List.
For the main CBA, the last digit of the board number, which is engraved on every board, should be a number (e.g. BA17F1F0102 4).
For the sub CBA, the last digit of the board number, which is engraved on every board, should be an alphabet (e.g. BA17F1F0102 Y).
