Preliminary Information 42PQ30
Y-SUS Board develops the Y-Scan to the Y-Drive boards.
This Section of the Presentation will cover troubleshooting the Y-SUS Board for the Single
Scan Plasma. Upon completion of the Section the technician will have a better
understanding of the operation of the circuit and will be able to locate voltage and
resistance test points needed for troubleshooting and alignments.
