Power Supply CBA Bottom View (sub Power Supply CBA)
CAUTION !
Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F601) is blown , check to see that all components in the power supply
circuit are not defective before you connect the AC plug to the AC power supply.
Otherwise it may cause some components in the power supply circuit to fail.
*
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).

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.
NOTE:
The voltage for parts in hot circuit is measured using
hot GND as a common terminal.
