When checking the P.C.B.:
Put a Cloth over the equipment. Put the MAIN (1), (5), (7)
and POWER (1) P.C.B.s together with the heat sink upright
on the Cloth and check them. (Fig. 6)
Reconnect all cables (connectors) that have been
disconnected.
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.
