speaker configuration.
Incorrect cable connections to the analog
audio jacks.
The component connected to the output (VCR

It is not possible to record the sound effect by
a recording component.
The internal microcomputer has been frozen
by an external electric shock (such as

Turn on the power to the component.
Disconnect the AC power cord from the outlet
and then plug it in again after about 30 seconds.
