PSR-S970:
Remove the two (2) hexagonal lock screws
marked [460] on the rear and the seven (7) screws
marked [440A]. The DMH circuit board can then be
removed. (Fig. 3)
*
After replacing the DMM/DMH circuit board, make sure to
execute the “ Factory Set” in the Test program.
*
Hardware ID is stored in the Backup ROM on the DMM/
DMH circuit board. If the DMM/DMH circuit board is
replaced, Hardware ID will be changed.
*
After replacing the DMH circuit board, be sure to execute
the test “068: NAND ROM Check2.” (p.48) (PSR-S970 only)
