Mercedes Harman / Kardon Logic 7 – amplifier repair
Harman/Kardon Logic 7 amplifier repair.
Harman / Kardon Logic 7 is a high-class sound system that was installed in Mercedes cars. It can be found in the W221 S-Class from 2005 – 2013 and the W216 CL-Class from 2006 – 2013. Unfortunately, sometimes even high-end devices are not immune to certain problems, which in the case of these devices can take a toll after several years of operation. A common problem affecting this sound system is the failure of the amplifier. The initial interruptions in the speakers can develop over time into complete loss of sound or other persistent car audio problems. A defective part may cause incorrect operation of the Comand NTG3 and NTG 3.5 systems. The repair of these problems at the dealership consists in replacing the defective components with new ones, which can be a large part of the value of the entire vehicle. Thanks to the work of our technicians, it is possible to repair the Harman / Kardon Logic 7 amplifier.
The most common cause of problems with the Harman / Kardon Logic 7 system is a faulty amplifier, which can manifest itself in several ways:
- no radio stations or radio tuner access
- automatic volume up with no response to volume down
- speakers malfunction – crackling, noise and buzzing coming from the speakers
- no sound at all
- Comand does not start or stops at the Mercedes logo
- the amplifier consumes additional current, which may lead to battery discharge
