When checking the P.C.B.:
• Reconnect all cables (connectors) that have been
disconnected.
Be sure to use the extension cable for servicing for
the following section.
POWER (1) P.C.B. CB601 – FUNCTION (1) P.C.B. CB307:
MF117350 (17P 350mm)
• When connecting the flat cable, use care for the
polarity.
• The P.C.B. removed from the rear panel does not
work because its grounding is loose. Be sure to
connect the ground of each P.C.B. to the chassis or
GND with a jumper wire or the like.
