Vehicles equipped with premium Mark Levinson stereo may experience no sound or volume that goes to maximum level by itself. An improved amplifier is available to rectify this problem.

Lexus LS430 Volume Control Problems With Premiun Stereo System
Lexus LS430 Problem
Average Mileage: 92,747 mi (40,000 mi - 217,550 mi)
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.

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!

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.

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?

No audio from ML system although screen shows all modes working. Also a rythmic, clicking sound at 1.5 sec. intervals overhead near center front (near where garage remote control is located). Sound returned for about 30 sec. 2 times but has not done so again for over a week.
