Question about Harman Kardon Audio Players & Recorders

1 Answer

Speaker fuse I turned the speaker, the light came on and then it went off. I checked the fuse and it appeared blown. I changed three new fuses since and they all blow when I turn on the power. I am running an AVR 1565 system. What are the correct specs on the fuse I should be using?

The problem is your system not the fuses which merely trip to tell you overload. So we have to find what is causing the over load.

SOURCE: Protector

If you took all the speakers off the reciver then it still goes into protect, the reciver detects DC on the output lines. That means there is a short in the output stage of the amp. It could be an output device, or a diffencal Transistor. If you can trouble shoot solid state electronics then you should be able to find the faulty, but if not your experienced at electronic repair, am afraid it may cost more then the reciveris worth. Good Luck PS please dont forget to rate this thread

SOURCE: Denon AVR-810 going into PROTECTION mode

It sounds like there is a problem with the differential circuit. The bias I am not sure about, as every unit is different. You should get the service manual to be sure or call Denon and see if they can give you an idea. Good Luck

I can help you solve this problem. However you must describe to me which fuse you have replaced. Is it the fuse on the power line or is it a fuse in the speaker line (which I highly doubt). usually this type of amplifier uses two technologies. One is transistors the second is integrated chips. This is in regard to the output stages. I assumed you speaker cables shorted each other while the volume was set at a high level with music playing. Anyway if you are willing I am able to help.

It's going into protect. Unhook ALL the speakers and see if it still shuts itself off. If so, then it will have to be taken in for service.

Power on, clock works, CD works, NO SOUND from the radio


Check the speaker wires maybe they have worked loose. And speakers themselves as they may blown. Do you have an amp if so check its fuse. Also check for inoperative interior lights, lighter, and horn. One of these circuits will power the radio's memory circuit. Some radio models will appear to work normally but have no sound if the memory fuse is blown. The clue is the clock will reset to 12:00 each time you turn on the ignition switch.

Of course it can be repaired, but not by us and maybe not economically. Take it to a tech.

Try disconnecting the speakers and a new fuse. Maybe it's just a speaker shorted. Low probability.

When i turn up the amp the 'current drive' cuts


Check all your wiring for short circuits, check your speaker coils are not shorted either - if you cant do this try any other pair of speakers on the system.

check the main capacitors in the power supply, check the internal fuses, and change the wall plug fuse - check all the large capacitors for closed/short circuit or cracked solder joints, resolder anything suspicious looking. the fuse could be **nearly** blown, and bend apart when it gets warm, change it to be sure... hope this helps.

Will the power light still come on if the fuse is blown?


To prove if the power light comes on with a blown fuse, just take the fuse out and turn it on.

If the light comes on your fuse could be blown. Replace it with the same rating. Let the guys at Radio Shack help out on that.

Fuse type: Radio shack 270-1062 or Equivalent.

ARS108 gone


Since Acoustic Research went out of business, I too have been looking for a solution similar to yours. I may have found an alternative to throwing away this really nice speaker. I found a company on the web that appears to sell an amp that may fit nicely into this speaker enclosure for $99.00. Check it out...

Logitech x 230 speakers "dead"


Razor Your correct, you will have to open it up however which may void a warranty depending on how long you have had it. It is possible the converter went bad, this happens in these. If this is the case Logitech is really good on replacement and price{ if you even have to pay} The link below is a test link you can try and also a Logitech forum with Logy employees that are really good with help and support. http://logitech-en-amr.custhelp.com/cgi-bin/logitech_en_amr.cfg/php/enduser/std_adp.php?p_faqid=2913&p_created=1125714076 Hope this helps.
