Rc mark levinson amp fixes?

Hi. I've had an issue with the audio not working when turning on the car, the red light is on but no sound whatever source i select, sometimes turning the ignition off & on will make it work again but sometimes not. I've read that this is common in the RC, is there a standard thing that you can do to fix it yourself?

I guess first thing is to find out what the issues is... 

If that is AMP dying (which would be similar to the way ML AMPs starts to die i.e. work at first after ignition, and then stop working after some time) then not much you can do short of replacing it. I don't believe AMP/AV is under warranty (if you have Relax), but if you play it smart then they may at least diagnose it for free and tell you what is wrong and how much it will cost to replace. The actual way it stops working may indicate cooling issue i.e. starts cold, when you play music it heats-up and shuts down, so I would check that ventilation is not covered and that fan is working (not actually sure if RC AMP has fan, but most of ML AMPs did).

The other question is why it is dying - in older SC/LS (the first cars to receive ML) it used to be just substandard components failing on the AMP or AMP overheating or both, IS had a drain flap which would get stuck and AMP would be water damaged, overheating as well was an issue (I believe I have seen reports of fan failing, or being blocked), RX/NX had drain issues with sunroof again flooding AMP (I am not saying any of these issues common, but they are the "common" between uncommon), but for RC I have not heard any particular reason why the AMP would be failing.

So I guess first of all you need to find out what is failing, secondly why it is failing. It could be something as loose connection somewhere, or corrosion on connectors, but my guess is as good as anyone else's.

Where is the amp & how do you get at it?

According to the parts diagram it is located in the boot (numbered 3) normally the right side under the floor mouldings.
