SOURCE: Problem with Marantz SR5500 Receiver

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.

How do i get my Marantz AVSR3053 out of protection mode?


Protection mode usually means there is a problem in the amplifier circuitry. You will need to have the unit checked by an authorized tech if the unit is under warranty.

I have a marantz sr 7001 amp and am running canton 4ohm speakers to front and centre should my amp get really hot and go into protect mode when I am giving it some serious volume


it is not made to drive 4 ohm loads.also if you measure the impedance on the speaker,at some frequencies,it is closer to 3 ohms.This will cause the amplifier to shut down.Today's amplifiers are embellished specs.the old marantz 2325 was 125 watts a channel and weighed 80 pounds.It would eat alive some of the 1000 watt home theater amps of today.Marantz is very nice stuff.

When i pout on my marantz sr-4320 receiver it is going to potrction mode i want to know how to reset it?


The protection mode is engaged when there's a shor on one of the speakers outputs. This is a major malfunction and, to prevent the rest of the receiver to get fried, the entire system is put in an emergency shutdown mode - the Protection mode.
You must find out if the short is external - in one of the speakers - or internal - in one of the amplifying circuits. For that disconnect every single cable that plugs in the unit and start it .
If the protection mode is still activated then the problem is internal. The only way to identify the faulty circuit is to open the unit and test them all one at a time, starting with the 4 final transistors (2 per channel) - you need a good voltmeter and some basic electronics knowledge. In the worst case scenario the final transistors for both the channels have been shorted - it will cost you about $100 to replace them. Beware, soldering them in place is a delicate job, use grounding precautions and don't overheat them.
If the protection mode is gone then one of the speakers has failed. Either replace both of them or take them to a specialized repair shop, you can't fix speakers at home.

Unit goes into protect mode


Not unless you know how to troubleshoot solid state electronics. If you disconnected the speakers and the unit still goes into the protect mode, most likely you have a short in one of the power output stages. Good Luck
