“PROTECTOR” appears on the display panel.
The receiver will automatically turn off after a
few seconds. Check the followings:
 There may be an electrical surge or power
failure. Unplug the AC power cord (mains
lead) and then plug in the cord again after
30 minutes.
 The receiver is covered and the ventilation
holes are blocked. Remove the object
covering the ventilation holes of the
receiver.
 The impedance of the connected speakers
is below the rated impedance range
indicated on the back panel of the receiver.
Reduce the volume level.
 Unplug the AC power cord (mains lead) and
let the receiver cool down for 30 minutes
while performing the following
troubleshooting:
 Disconnect all of the speakers and
subwoofer.
 Check that the speaker wires are tightly
twisted on both ends.
 Connect the front speaker first, increase
the volume level and operate the receiver
for at least 30 minutes until it completely
warms up. Then, connect each additional
speaker one by one and test each
additional speaker until you detect which
speaker is causing the protection error.
After checking the above items and fixing
any problems, plug in the AC power cord
(mains lead) and turn on the receiver. If the
problem persists, consult your nearest Sony
dealer.
