Most often it is due to improper speaker loading. In other words, it needs to have from 4 to 8 ohms speaker load and you wired your speakers in parallel when they should have been wired in series. What would have been an 8 ohm speaker load in series, turns into a 2 ohm load when in parallel. And with dual voice coil speakers you just compound the problem. And don't even get me started on bridged outputs.
Anyway that is what usually causes an amp to fry. Good luck.

Tip

Marantz SR-7200 reset


This was documented on the Marantz website briefly a year ago and is no longer available. My SR-7200 develops "click/pop" problems and a reset cures it of these issues.

While powered "off," on the front panel, press: A/D + FP +Dimmer (3 buttons) and power the unit on.

This reverts to original (out of box) settings. You then must reprogram input sources, speaker setup, levels and radio stations.

The receiver is turning itself off - i.e back to standby.


If you don't use the remote control is it okay? If so, tear apart your remote control, use a Q-tip to clean all the lines in the circuit board where the rubber contacts touch. Then make sure that the rubber buttons don't have any 'gunk' on them that are making them stick. Clean the rubber pad with a qtip with dishsoap. Dry well, put back together and see if she works. Report back on your success. Good luck.

Marantz sr-7200 no OSD


Press AMP then OK on your remote. If the menue does not appear press 9 on the remote. You must have your monitor connected through composit Monitor Out or S-VHS.
Also check your multiroom settings. Maybe your OSD signal is diverted through to other room. I do not have SR-7200 any more, unfortunately.

Marantz SR7500 Home receiver, Digital CD will not play


Verify that the digital output is enabled. This is a switchable output. A brown-out or other power isseu may have shut it down.
Get back to us if that is not the case.

DSP (Digital Signal Processing) Board is probably defective or has Poor solder Connection on one of the Ic's on that board. Board cannot be Obtained from Marantz. Must be troubleshot at component Level and requires a very knowledgable tech to repair it. I have done a few of these in the past and usually charge $50 to Evaluate and Give estimate. kstahl65@att.net

It is likely that the PA stage has developed an offset voltage in the output stage. The faulty amplifier channel can be found by progressively disconnecting the collectors of the of the power transistors until the protection fault disappears. Once the faulty channel is found the the cause of the offset has to be traced to the faulty transistor or resistor. Don't forget that if you can smell smoke or burning then there are likely to be components(esp transistors) that have been damaged by the fault.
I had a Luxman unit that destroyed 5 transistors in the output stage that was due to an open .5W resistor in the driver stage.
Good luck.
