Daniel24 Posted August 18, 2011 Share Posted August 18, 2011 I recently experienced a complete muting of the Nakamichi in my 1992 Ls400 (99.5% restored to new condition as of today). The forums suggested a reset of the ECU, but that didn't work. After much fussing around, I removed the unit from the dash to check out the wiring. By accidentilly pulling the blue plug for the old on board cell phone from the lower back of the unit...the sound returned good as new. While this may be very elementary for most of the people on the forum, it may be helpful to others and save a huge amount of fooling around time. The reason was apparently that the phone was designed to "take over" the speakers when in use and for some reason that was the case in this instance. By unplugging the blue plug, the phone was disabled and the sound came back. Those phones were analog anyway and no longer are usable. So, for those of you who cherish your Nak try this before you replace your stereo unit when you experience a sound outage in your unit.
