The speakers don't work at all. The blue light goes on fine, but there's no sound. They used to work fine with my iPod and iPhone, but not anymore.

Hi, Have they been turned off?
These speakers have a habit of setting their volume level to zero if the power is removed.
At the bottom of the right-hand speaker you should see some tiny volume up/down buttons.
Try pressing the up and see what happens.

I bought the hk3480 about 6yrs. ago. It was put in a rack and tested and then sat for the next 4yrs. unpluged. I got home and pluged it in hooked up some speakers and iw lit up all functions work etc....

Never use maximum volume for troubleshooting. The errant switch or control that you eventually find and flip will suddenly release the amp's full power and you'll destroy your speakers. If a signal isn't audible at 1/2 volume it's probably not there.


There is a good chance that a common control may have developed a high-resistance or 'dead' spot through idleness and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the Mute control.

Turn the volume to something reasonable and see if that helped.

Need ac adapter for speakers

If you're in the US, go to Radio Shack and buy a plug in transformer that puts out 12VDC at 1000mA.
The polarity is negative (-) on the outside and positive (+) on the inside.

UGH! HK 395 speakers not working on my Dell XPS 400 computer since A new hard drive was installed. I can tell they turn on, but my computer does not recognize them. Dell directs me to Harmon Kardon and...

How old are the speakers. They will power on, however, when transformers get old what will happen is the voltage will rise above tolerance and damage parts of the motherboard.

Get this checked out with a multimeter first. The rating is on the transformer. You should not need any drivers to get basic sound out of them.

If they are in tolerance, then go to the sounds applet and see if there is a selection of devices you can use. Sometime you have a video card that also will do audio.

Harmon kardon 745 displays "unlock" no sound for tv or movies

I also had this UNLOCK message on my Harman Cardon AVR 130.
The reason for this error was - in a hurry I've plugged the optical input into optical OUT! Double check that your connections in the back are correct and hopefully it fixes your problem.

Cheers,

80 watt impedance matching volume control

check your spekaer cabling first for any loose connection. if everything as usual then something is wrong with either your speaker system or the power output stage of your amp. you may call it a "circuit breaker" but it actually overload protection of the power amp so as not to damage speakers or amplifiers. have your speakers checked for burn coils. you can also try to remove or turn off speaker switch, turn on the power, level up the volume and see it the system still stays on and does not trip (as you called circuit breaker) if the unit remains on, then it must be your speakers. though it could also be a leakage in the power transistors of your output stage, it something a technical person have to do to check anyway.
