Receiver turns off after it has played for a few minutes. I reset the light and it will run again for a while and then turns off.


There are a few possible causes:
1. Your receiver is broken.
2. One of your speakers has a short in it.

To tell which, disconnect all your speakers at the back of your Marantz, and turn it on. Does it stay on? If yes, then check your speaker wires and speakers one at a time for normal volume...

I HAVE A MARANTZ SR880. WHEN I SWITCH IT ON, IT STAYS ON STANDBY MODE. WHEN I SELECT INPUT, IT CLICKS AND THE STANDBY LIGHT FLICKERS. WHAT DO I NEED TO DO?


Hi,
Possibilities for dry soldering. its a Common problem with this model. Also can happen because of aging . Its tedous procees to open and repair the av receivers. Its better to find expert who can do it for you. i think Marantz authorized service center will not do this as its an out dated model .

Either chanell cuts out randomly. It is not over heating, and does'nt happen all the time. Otherwise sounds great. Marantz 2230. thanks in advance. Steve


Intermittent problems are no fun to troubleshoot because you have to force it to fail or wait for it to show the problem. It sounds like it could be a thermal problem or a cold solder connection. Do you hear the sound through the headphone jack on the receiver when the speakers blank out? If so your pre amp section is working, and it is in the power amp section. If not I would first use a spray contact cleaner on the switches and rheostats. Click on the link below for Cleaner.

Second, wait until the unit exhibits the problem then use a freeze spray selectively spraying parts of the board and components until the sound returns. You can use a heat gun sparingly to heat parts of the circuit to try to force it to fail. If you selectively freeze spray the board and sound returns you need to inspect the board for broken traces and touch up solder connections, which could be cold and faulty. If you spray a component and the sound is restored it could be a bad component, and it should be inspected. Click on the link below for freeze spray.

I have a Marantz SR5500 and the unit will not stay powered on.


I have this problem. it is caused by an o/c mains transformer primary winding. the clicking and flashing light is the stanbyy circuit trying to switch the power on to the main (large) transformer when it gets no voltage out it switches back off
