Service Manual
32HFL5763D/F7 (Serial No.: DS1)
32HFL5763L/F7 (Serial No.: DS1)
In this service manual, there are some models which consist of two Inverter CBAs.
The main Inverter CBA and the sub Inverter 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 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).
