Troubleshooting

Cause
The power cable is not connected or the
plug is not completely inserted.
The speaker impedance setting is
incorrect.
(When this unit is turned back on and
"CHECK SP WIRES!" is displayed.) The
protection circuitry has been activated
because this unit was turned on while a
speaker cable was shorted.
The internal microcomputer is frozen due
to an external electric shock (such as
lightning or excessive static electricity) or
by a drop in power supply voltage.
The internal temperature becomes too
high and the overheat protection circuitry
has been activated.
The protection circuitry has been activated
because of a short circuit, etc.
The sleep timer has turned off this unit.
Speaker cables are short-circuited.
"Memory Guard" in the SETUP menu is
set to "On."
The video software is copy-protected.
Remedy
Connect the power cable properly to an AC wall
outlet.
Set the speaker impedance to match your speakers.
Make sure that all speaker cables between this unit
and speakers are connected properly.
Disconnect the power cable from the AC wall outlet,
wait about 30 seconds and then plug it in again.
Wait about 1 hour for this unit to cool down and then
turn it back on.
Check that the speaker impedance setting is correct.
Check that the speaker wires are not touching each
other and then turn this unit back on.
Turn on this unit, and play the source again.
Make sure all speaker cables are connected correctly.
