No sound coming from stereo (factory default Mark Levinson system). The system controls all appear to be working except the volume control--doesn't display a current volume (no sound is coming out ) and neither turning the volume dial nor adjusting the steering volume control causes anything to happen.

Mark Levison system,LS 430, Navigation shows all functions of the radio, on/off, am fm cd. In CD mode it shows time for song playing, but no sound. Six months ago if i turned the vol knob, the volume would come on full blast. Now it may be several minutes or hours that it will come on, but i must always turn the volume knob. Some times it plays, other times not. when not playing and i go to the sound screen there are no bars for fade, balance, or bass/treble/ midrange. While playing i do have the adjustable sound bars. Most of the time the radio does not play. The navigation and climate control functions work fine.

Volume stuck. Must turn vehicle off to "reset" volume working correctly.
Sound quit functioning.

Sound crackles, hisses very loudly, then cuts out altogether. Just waiting for the amp to fry completely. Sometimes the crackles and hisses are at full volume, which is really jolting and irritating.

Initially when I bought the car at 60,000 miles, the stereo sound would fade in and out, I would just turn the knob back and forth and it would fix it until I switched stations. Fast forward at 148,000 miles and it's everything described in everyone's feedback. The sound just recently started fading from low to loud blast, the speakers crackle when the radio is supposedly turned off. And the sound just fades out for quite a long time so I keep jiggling the controls so I can hear at least some of a song...so exasperating. Lexus probably knows what's wrong but want $110 to investigate it. At least my car's running (has knocking sound) I guess but still...

Amp just died, after a week of static and crackles that start happening randomly. Amp cant be repaired here in NZ, what a load of junk!

First, rear speakers started buzz, then went off. The radio started intermittant on-off. Some times when it does come on it is full volume and cannot be adjusted. Looking for solution. Can I assume it is the amp in the rear panel?

Amp stop working about 3 years ago replacement cost $800.
screen shows audio off !
my radio lost sound. However, all the radio functions appears to operate, I.e., locking on to stations, providing station information on the LED display. Map display, Bluetooth connection. Just no sound!

About once a month on my Lexus SC430 the ML sound system has no audio but moving the volume control brings the level to full volume that blasts one out of the seat!
It blew out the speaker and has not been fixed

Radio will not have any sound on the back speakers when fader is on back speakers to use it fader must be all the way to up front speakers only take the fader to back at all and you hear sound and nothing and sound and nothing. the only way you can listen to radio at all is with fader all the way on front speakers Mark Livingston system.
