Marantz Model SR5500 AV Surround Receiver. Intermittent fault with "Power Switch" on front console of unit. I turn system on by use of remote and a short time later the "Power Switch" switches itself off momentarily and then attempts to switch itself on again, it does for a micro-second and then again switches off/then on/then off. This will repeat until I manually turn the "Power Switch" off. It is almost as if the contactor is not able to close properly. There is a distinct mechanical sound to this operation. Any suggestions? Regards Mark Hogan

are all the speakers connected 1.5s
all the same watts helps
is that one with an inbuilt amp ?

what a mess or connectors at the back of one of these

The POW5 fault indication means that the 5Volt power supply grid is not OK. The unit needs to be repaired by a professional repair engineer. No user servicable parts inside.

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

I have exactly the same problem! Sometimes when I turn the input dial it comes back on but this time it is out for good. I have tried re-wiring and unplugging etc. nothing seems to work.

For resetting sr6001: When power lights blinking, press "clear" + "pure direct" + "7.1 ch input" simultaneously for 3 seconds.

Hi, hope this helps, try (1-800-remotes), these guys have a wide selection.

Try pressing the power, and multi speaker button at the same time. But first turn the unit off...then press the above buttons at the same time...This is for the SR6001... GH

Sounds like you have an issue with your electrical circuit. Your receiver could be receiving spikes of current from the electrical wiring in your house.

Review your current electrical situation. Keep in mind that certain outlets are on the same circuit and that running multiple, high-wattage devices on the same circuit can cause issues with some of those devices. Especially when it comes to turning devices on and off.

Many devices take a sudden, rapid charge to power their circuitry the moment you turn the device on. Home audio and HVAC systems are particularly notorious for doing this. Other devices on the same circuit can sometimes suffer influxes of power flow and may either turn off or go into standby mode to protect themselves from the resulting surges.

I've lost audio systems that way... I lived in an apartment building that has wiring most likely dating back into the 40's. I once turned on a space heater on it's max 1500 watt setting and blew my Logitech Z-680 speakers. (The "BOOM" sound that emitted from my subwoofer was AMAZING. I had just blown an amp circuit. It literally exploded inside of the subwoofer. Took pics and everything.)

If you have the means to do so... You might consider re-wiring your electrical circuit. Take into consideration where you're going to run certain devices and wire the system accordingly.

In the meantime, you would want to be sure to buy a HIGH-QUALITY surge protector for the audio system. Spend a few bucks and get a GOOD one with a good warranty on it. Don't use those cheapy ones that we only really use to split the outlet. NOTHING under 1,000 joules.

My receiver sometimes locks itself like that, though. If we have a power outage or the unit is unplugged suddenly, it will keep itself in standby mode until you unplug it, press the power button a few times to discharge any current left in the capacitors and plug it back in normally. Only then will it turn on again.

Let me know what you come up with.
