Question about Nakamichi SoundSpace 5 Shelf System

1 Answer

Nakamichi Blond Moment

My wife stapled a speaker wire and obviously shorted something in the system. The receiver appears to be functioning, but I'm getting no sound from either speaker.

I've got what looks like 3 rails of 20VDC coming out of the power supply - I don't have a schematic, so I'm flying a bit blind here, but that seems about right. I'm guessing the malfunction is in the amplifier, but I've not yet taken the back off.

Any recommendations

Hi Ho There,

The speakers can be driven to make sound by several different power devices, These devices can be FET's or Transistors, or a output Integrated circuit.

All of these devices can be damaged by shorting the speaker wires I suspect thats what has happened in your case...

The manufacturers provide internal p[rotection and this can be in the form of a fuse which will beaccessible from the ouitside of the case.

Have a good look to see if there are any fuses there that are blown that you can replace yourself...Please replace with the same value type as fitted already...

If you cant locate any blown fuses then it will need to be taken to a service person to strip the cover off to see if there are any fuses that can be replaced inside....otherwise it will need to be repaired especially if the output device is damaged in any way..

If you are lucky it should be just a fuse as the "wifey staple" would most likely have shorted out omly the one channel, and as you say both channels dead then its more likely to be a fuse that supplies all the output stage devices that has disrupted..

Good huntind

YUBEUT.

Generally speaking, an amp protects 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.

In your case it is obviously not heat, speaker load or excessive volume at the moment.

You could unplug it then turn it upside down and shake it to see if something metallic is rattling around inside it. Maybe open it up and sniff for burnt components, but even if you see something obvious and replace it you migh not know what the original cause for failure was, so you may just be wasting time and sacrificing new parts.

Check the speaker wires and be sure they are not shorted. If no obvious signs, remove alll speaker wires and check system. It could be a short in the wire, a bad speaker, or a problem in the receiver.

My Denon AVR 1010G displays "PROTECTION!!!" AND cannot function further more. How to make it function properly?


The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

I have a Denon AVR-587. It has worked fine for 2-3 years, but ever since I tried to connect it to a different set of speakers, it cuts out after a few minutes and I hear this loud clicking sound coming...


There is a short either on the speaker wires to the speakers or the speakers are defective (some sort of a short or too low of resistance). Lastly, check to see if a stray strand of wire is not touch the left and right terminals. Any short in the network (wire, lack of insulation, staple, screw, etc. ) will cause the system to clip.

Won't power up; push power button on, hear click in back left of unti, get nothing on front display and no output from speakers; as if unit trying to operate


Disconnect the speakers and see what happens. Carefully examine the speaker cables for unwanted connections (shorts).
Take a clue from when the power problem appeared. Something was moved and made the buzz a (probable) dead short.

If you are using the speaker out wiring (not RCA) then disconnect all speaker wires. connect only one speaker or use a known good test speaker. Try each of the 4 speaker outputs. If none still do not work, then it sounds like a blown output chip which will need to be replaced.

I was having this problem and after research on internet found that this could be because of speakers wire being short. I recheck all the connections and most likely have short due to wires being stapled on the wall and staple causing short. It is working fine now for me. Check your wires...
