Troubleshooting
Problems and remedies
When the STANDBY indicator
flashes
Immediately unplug the mains lead and check
the following items.
• If your system has a voltage selector, is the
voltage selector set to the correct voltage?
Check the voltage for your region, then
make sure the voltage selector is set
correctly.
• Are the + and – speaker cords short-
circuited?
• Are you using the supplied speakers?
• Is anything blocking the ventilation holes
on the rear of the system?
Check all the above items and fix any
problems found. After STANDBY indicator
stops flashing, reconnect the mains lead and
turn on the system. If the indicator still
flashes, or if the cause of the problem cannot
be found even after checking all the above
items, consult your nearest Sony dealer.
