Speakers. Repair procedures

Inspection

Troubleshooting for Speaker

(1)	Basic inspection of speaker Inspect the sound from speaker after verifying that the speaker mounting screws is removed and the wiring connector is connected precisely to remove vibration transmitted from body trims and surrounding parts.

(2)

Case Troubleshooting

No.

Case

Inspection/Remedy

Trembling sound

1)	Before replacing the speaker, inspect that the mounting screw is installed normally.

2)	After re-installing the speaker, verify that no trembling sound is heard.

3)	When hearing a trembling sound again, replace the speaker with new one.

Noise

1)	Check if the wiring connector is connected normally. If not, reconnect the wiring connector.

2)	In case of radio static, check if there is a noise from CD player.

3)	When a noise is heard on turning radio and CD on, replace the speaker with new one.

In case there is only radio static, this causes from poor radio reception. Thus the speaker needs no repair and replacement.

Poor working

Inspection of the wiring connection between the battery and the speaker

1)	Before replacing the speaker, inspect the wiring and connections in the speaker circuit.

2)	Check the supplying power to the speaker and the resistance, and then inspect the sound quality.

3)	If the speaker works poorly, replace it with new one.

–	During dealing of speaker

–	Dropping or rough handling of the speaker can cause damage.

–	Be careful not to cover water and oil over the speaker.
