Hi HouseofBlues

The problem you are facing is the speaker protection is turning on to prevent the amplifier from damaging your speakers. It will need some service work done to it to prevent it from happening. I suggest you get it attended to sooner than later, as the problem will be caused by dry solder joints that will need to resoldered, or a semicinductor that is failing. If you are a gun with a soldering iron, you could do this yourself. Check about parts of the amp that runs hot, particularly transistors and resistors in the output stages. resolder all output transistors, and any parts that are mounted to a heatsink. Also focus on areas of the PCB that has discoloured. This is often where the problems occur.
I am more than happy to answer any other questions you may have about it, just give me a hoy :)
Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.

When i receive calls, I can hear them but the caller cannot hear me


Find the Mute button and turn MUTE back on. It cuts off the microphone so you can talk in private to someone without the caller hearing.

Marantz problems


The speakers are 8ohms. Always try using speakers 6 or 4ohms. For B&W 683 on PM 6004 is too low. You should go for PM 7000 or 8000 series to catchup with 683. Also when you increase the volume please decrease the bass as well.
You need 8ohm 55w to 90w or 4ohm 80w to 110w speakers.

Mute light flashing


Is the amp otherwise functional? If not- check to make sure the speakers are hooked up and not shorted.

If it is functional and on AM or FM mode, it may just be the station signal is not adequately centered so part of the carrier is not being detected by the PLL and the between station muting is kicking in.

Marantz pm 7200 loudspeakers do not cut off when headphones pugged in


Some amps have a button which you press to mute the speakers when the headphones are plugged in. Sometimes marked "Speakers on off". If it hasn't then a new headphone socket would not be expensive to fit. As long as the amp producers sound I don't see any future problems. The previous owner may have used the headphone socket a lot, and simply wore it out!

Volume Stopping Instantly


A few things to consider: if mute on the set is not on what about the box if you are using one?

Speakers could be switched off in the set.
There could be a internal / external speaker switch(not common but possible)
Sound on the set could be muted or turned real low or off.

if the image you see on the screen is there--either it is from the set or a box if one is used.

only a few things other than the sound circuit being bad will cause this--very few sets with actual no sound problems are around.

I am having radio and cd trouble. My radio in very low and the mute button don't change a thing but you can see that it is showing mute but the sound is the same. After cutting the switch off in about 30...


There is a voltage for sure generated by the mute switch or the controller to cut off amplification in the audio amplifier. Since you have noticed the mute on the display, This must be disabled to get the volume back. so the circuit must be traced to confirm on the MUTE output and the voltage cut off to remove off the semiconductor switch.

Marantz pm 7200 lost sound, only works when volume is up high, still looks like there are no high or medium frequencies.


You have either lost the pre-amp stage or the Main Amp stage. Since you have a problem on both channels it most be a part that is common to both channels. Something like an IC I would suspect.
