Hi kerrijon

Oh dear, your budding lil electrician may have gotten out of his depth:).

Shorted speaker wires often result in damage to the amps output stages. The blinking light tells us that the unit has gone into protection mode, preventing damage to the speakers from the amp. It will have what is termed a DC offset condition being generated by the channel; that got shorted. There is no easy fix for this and you have checked the obvious with fuses and removing all speaker wires and checking operation. The unit will have a blown output transistor/array, possibly driver transistors, and fusible resistors, and diodes to that channel. The bias current will also need to be set up again once repairs are completed.

There are no user serviceable parts in a unit like this. With good knowledge of electronics, a multi meter, soldering iron and experience at using all, you could fault find the channel, replace the parts yourself. I should warn you that if descrete components are used, they can be difficult to repair because of the nature of DC coupled linear stages employed. The best option is to take it to a repair man for a quote.

I am happy to try and talk someone through a repair process, but there is a degree of difficulty ascociated with not being able actually work on the amp.

The best solution for you is to get a tech to look at it. This sort of repair work can range from $80-150 depending on the parts used and the time taken to fault find and replace parts. I hope that this helps you. Your appreciation for my time spent to give you this advice is best rewarded with a FixYa.

Cheers

SOURCE: I have a marrantz sr7002 The red blinking light

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

If your turntable has an stereo output through it RCA output connector make sure that the RCA cord you are using is new means there is no cut of wires inside it .check the continuity by connecting the RCA cord to the auxiliary input of your reciever then touch the plug with your hand.you should hear a loud humming audio left and right following which plug you are touching.it means the cord is good.if only one channel you hear then replace the cord.good luck..

All of a sudden stopped working and won't turn back on. been 12hrs. when power is pressed, it turns on for 2 seconds and then standby lights blink again and it turns off


This could be caused by a direct short circuit on the speaker outputs. Try disconnecting all the speaker connections at the back of the receiver and then power back on. You can also try a factory reset by holding the surround mode + clear button for 3 seconds.

My sr5004 marantz receiver has gone into standby with the indicator is blinking how do i get ride of it


If the red led is blinking fast (8x/second) the power supply is likely damaged and the unit will need to be serviced. If blinking slow, the most likely cause would be a shorted speaker connection. To help find the cause, unplug everything including the power and speakers. Connect only the power and try to turn the unit on. If the light doesn't blink, you know you have a shorted connection. Power off and connect the inputs and then power back on. If the light is not blinking, you know the problem is with an output connection. Just find the bad connection by process of elimination.

Are the speakers connected?

If so , you have an output DC voltage issue ( typically outputs dont want to see more than 100mV DC going to the speakers. If that happens , the Protect circuit will kick in. Find a repair tech in your area because I think this amp is worth fixing

PROTECTIVE FEATURE


In some cases, the STANDBY indicator may blink slowly, twice per second. In this case, turn off the unit, unplug the power cord, and check the following points.


Make sure the speaker cables are not reversed and connected to the wrong sides (+ and -) on the unit.


Make sure the speaker cables connected to the unit are not shorted. (Check both the unit end and the speaker end.)


Make sure the volume does not exceed the level that the unit is capable of producing.


When using the unit in a rack or other enclosed space, heat may build up inside the unit and cause a fire. When installing the unit, be sure to leave suffi cient space between the top, back and both sides of the unit and walls or other AV components to prevent the internal temperature from rising.


After checking these points, plug in the power cord and use the remote controller to turn on the unit. Turn down the volume before resuming playback. Confirm that there are no problems with the speaker connections and playback performance.


If this symptom recurs, request service at your nearest service center.


In rare instances, the unit may enter standby mode and the STANDBY indicator may blink rapidly, 8 times per second. In this case, unplug the power cord and request service at your nearest service center.
