Inverter Schematic Diagram (main Inverter CBA)
When you conduct on a component level repair for the Inverter CBA for any models within this service manual,
make sure to refer the right Block Diagrams, Schematic Diagrams/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. BA17F4F0103 2).
For the sub CBA, the last digit of the board number, which is engraved on every board, should be an alphabet(e.g. BA17F4F0103 Z).
