The power cable is not connected or the plug is not completely inserted. Connect the power cable firmly. The receiver has been exposed to a strong external electric shock (such as lightning or strong static electricity). Set the receiver to the standby mode, disconnect the power cable, plug it back in after 30 seconds and then use it normally. No sound Incorrect input or output cable connections. Connect the cables properly. If the problem persists, the cables may be defective. No appropriate input source has been selected. Select an appropriate input source with the INPUT selector on the front panel (or the input selection keys on the remote control). Speaker connections are not secure. Secure the connections. The volume is turned down. Turn up the volume. Signals the receiver cannot reproduce are being input from a source component, such as a CD-ROM. Play a source whose signals can be reproduced by the receiver. The sound suddenly goes off. The timer has turned off the receiver. Turn on the receiver, and play the source again. Sound is heard from the speaker on one side only. Incorrect cable connections. Connect the cables properly. If the problem persists, the cables may be defective. There is noise interference from digital or radio frequency equipment. The receiver is too close to the digital or high-frequency equipment. Move the receiver further away from such equipment.
