corrective action.
If the problem persists after doing all of the
above, consult your nearest Sony dealer.

Immediately unplug the power cord and check
the following items.

voltage?
Check the voltage for your region, then make
sure the voltage selector is set correctly.
• Are the + and – speaker cords short-circuited?
