Hello fellow LS430'ers,
I have a 2004 ls430 ML whose radio turns on, but does not produce sound. However, the voice command produces sound just fine (so probably not speakers), and if I merely turn the electronics on and don't crank the engine, the radio will work for about 3 seconds, then silence. Any suggestions, other than fuse maybe?

 

It's got to be something in the Amplifier, mounted back in the trunk, but to be honest I couldn't tell you past that. Do any of the radio functions work? AM, FM, Tape, CD?

I know these amps are susceptible to failure, and it's not out of the realm of possibility that yours is failing.

I have to assume the voice command works off an amplifier in the head unit behind the touch screen..

There have been a few really good threads on this Audio System, and there's a few guys who have had their amps rebuilt or fixed.

Feel free to search for Mark Levinson Amplifier issues and you may be surprised with what you find.

Welcome aboard!!

 

That makes sense, I checked the cd player and it doesn't make sound.
