Hello to all,
I have a problem with my cd player cd73.
worked perfectly the last time that I listened to music.
today I power on it, press play, the disk turns but remains mute. no music...and the other command do not work (next, forward, ecc). I experienced to open it and I have heard that the mab8410 became very hot and also the cx7934 it is heated a lot. What does to be happened?
i haven't the service manual, anyone have one to sell me ?

I have got same problem as you. mab8410 is micro control chip with cpu & programed inside. I found it defacted when I checked pin 15,16 for the system clock. also very hot . My marantz cd 73 can't work because I am still looking for this chip mab8410 (B002C).
The version number should be the same.
