Fuse replacement
When replacing the fuse, be sure to use one
matching the amperage rating started on the
original fuse. If the fuse blows, check the
power connection and replace the fuse. If the
fuse blows again after replacement, there may
be an internal malfunction. In such a case,
consult your nearest Sony dealer.
Warning
Never use a fuse with an amperage rating
exceeding the one supplied with the unit as
this could damage the unit.
Cleaning the connectors
The unit may not function properly if the
connectors between the unit and the front
panel are not clean. In order to prevent this,
open the front panel by pressing

, then
detach it and clean the connectors with a
cotton swab dipped in alcohol. Do not apply
too much force. Otherwise, the connectors may
be damaged.
