no sound

[carguy1967]

Hi All
I have a 2013 200 with no sound what so ever!
DSP does not display, bass/treble fader/balance light up but can not be adjusted.
So far, I replaced: amp, head unit (top & bottom), telematics(behind center console)
I have replaced every fuse. im lost on this one
Help

Did you get this figured out? I have a 2008 that has lost output to half the speakers (right side) and is weak to the rest. Where did you find a replacement amplifier 86280-Ow520? I've only been able to locate a used one in the UAE.
