Service Manual

32PFL1507/F8
In this service manual, there are some models which consist of two Power Supply CBAs.
The main Power Supply CBA and the sub Power Supply CBA are compatible with each other
for a board level repair but they are not compatible with each other for a component level
repair.
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 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. 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).
