Do not reverse the brown and blue line-filter leads when replacing the line filter. They must be
connected
as
shown in figure 6-31a. If these leads
are
reversed, there will be no fuse protection.
If the plastic coating on the
two
large capadtoIS (C4 and C5) is saatched, replace the capacitors.
Otherwise a shock hazard will result.
Note that the mounting screw next to the large capacitor (C4) has no star washer. This prevents possi-
ble damage to the coating on C4. Make sure that you use the washerless screw here when reinstalling
the power supply.

serious damage to the power supply or the logic PCAs will result.
