Symptoms and Conditions
A customer may have a complaint as follows: if the CD volume control is set at 2/3 or greater, the output amplifier suddenly shuts off. Sound will not return until the units main power is turned off and then on again. The overvoltage protection circuit of the output amplifier activates thus shutting off the sound to the speakers. The conditions necessary to activate this circuit are:
- Battery voltage of 14.4V or more
- A loudly recorded CD
- Volume control set at 2/3rd or greater.
This self muting of the sound output is more likely to occur when using a loud recording of a CD with the standard 4 speaker sound system, although this can also occur with the 9 speaker premium sound system.
Vehicles produced on 6-30-99 and later have a modified unit installed at the factory. Beginning on July 20th, vehicles at the ports began receiving modified radios. These units can be identified by a brown or green label located on the removable protective film located on the face of the CD player.
If a vehicle has a customer complaint of this type, replace unit with a part from dealer stock. Panasonic will supply two units to each dealer, one single disc CD player and one six disc player beginning with the first week of August. After replacing a defective unit, call Panasonic at
800-331-2937 and request a replacement unit for dealer stock.
*** Do NOT attempt to repair vehicles in dealer inventory. Use stock units only for customer complaints.
There is NO change in part number.
