Function CBA
Not Used
IR Sensor CBA
Inverter CBA
NOTE:
The voltage for parts in hot circuit is measured using
hot GND as a common terminal.
Because a hot chassis ground is present in the power supply
circuit, an isolation transformer must be used when repairing.
Also, in order to have the ability to increase the input slowly,
when troubleshooting this type of power supply circuit,
a variable isolation transformer is required.
Inverter CBA, Function CBA & IR Sensor CBA Top View (sub 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).
