Mark Levinson audio dead
My Mark Levinson audio system died in my 2002 LX-470. No CD, no radio, no antenna. Two questions. 1. How can I tell if the ML amp is bad or it's just the control panel? and 2. If it's the amp, some time ago a forum member mentioned a company who sells new or repaired ML amps on an exchange basis at a much cheaper cost than new or on EBay. Anyone have that info?

Mark Levinson fix
I decided to try to fix my ML amp in my ES330 myself.
I found one tiny component causing the problem: A blown capacitor. It was clearly rattling around the case and the internals were flopping around as well.
I identified the part number as "Nichicon PW series 39uF 16V aluminum electrolytic capacitor"
I will order a couple and fix the one that was out as well as possible the one next to it.
The amp was in my trunk. If you can find your amp and choose to repair, just know that you'll need a Torx T10 and a 5/16 socket wrench to open the amp.
There are screws under the Mark Levinson label on the amp
Hope this helps.
If you want to save time but spend a little more money,you can find your part number and replacing it with an identical model from one of the many sites on the web.

I know this is an old thread, but if your amp is dead, it will likely chirp when you try to play anything. See video linked to below.
Usually when control panels go out, you start losing the ability to do certain functions, like change or seek radio stations or tracks on a CD.

Almost any electronic repair tech should be able to fix this for $100 to $200 max.

Mark Levinson audio dead
For years I thought either my amp or control unit died in my 2002. Then a few weeks ago, I accidently pushed the ON switch when going over a speed bump, and Magic! The antenna went up and the CD player began playing a disc. Functionality lasted for about 2 weeks, then just as suddenly, it stopped working again. It's still dead with no audio, no antenna control - nothing. Well, at least I know that there's nothing wrong with the Mark Levinson amp. I think I've got a loose (not on the amp - I checked those connectors) or shorted wire somewhere. And from what I've read on this forum, it could be anywhere...

So, I'm just reading this, I know it's late but chuckb669 and eng2000g, not sure if you got the problem resolved, but years ago tht was a grounding issue. If your radio came on from the bump then it may have grabbed enough ground to come on. Check the ground under the hood that connects to the car and see if it has a good clean contact. Hopefully you guys both have the issues resolved

Amp Died on my 07 460L w/ ML. I guess I'm not too upset my car has 132k. Went to a local shop who quickly told me there was nothing they could do. They told me to bring them a new amp and they would install for $350....I almost laughed at him...In fact I did but I had my mask on. Anyone have anything new on this issue?

My '07 LS460 started that sound last night. A Lexus tech removed the fuse from the front passenger side but now there is NO sound whatsoever. I'm trying to weigh the advantages of purchasing a refurb or removing mine and sending it in for repair.
Can you shed some light on the pros and cons?
