Question about Harman Kardon AVR 25 MKII

1 Answer

Static and popping from Harmon Kardon AVR 340

ONE month out of warranty, I began hearing constant static and occasional static popping from my right front speaker. I though I had blown the tweeter, but when I plugged in the left front speaker to the right front output of the $600 HK AVR, the same static was now in the left speaker. Thus, it was not the speaker. Both Circuit City and the HK authorized service center confirmed the problem. HK graciously authorized a courtesy repair to no avail – three months at the shop and I got the problem back. Has anyone had this problem resolved short of a getting a refurbished replacement (garbage) from HK? Should I just give up, buy the Denon, and lesson learned?

Hi,

You seem have a problem with a component in that channel, the bad news is that it is hard to fix that type of problem (you would be better off if the channel died). All of the components in the final output section are part of the same audio loop (per channel), which makes it hard to find the faulty part.

Sounds to me like a bypass or coupling capacitor is faulty or need to be re-soldered, either way to fix this problem you should take it in to a repair shop.

I hope that helps and sorry for the bad news.

When i turn on my harmon kardon avr 165 it shows ''Protect'' and then it turns off again?? what can i do :)


I would try disconnecting the speakers, then turn it on. If protect still shows with no speakers connected, then it needs to go to the repair shop- Might be a blown power transistor.

My Harmon Kardon AVR 2600 goes to protect mode when powered up. After many tries it will fire up but at times it's up to twenty times. I did load the software upgrade 6 months and it has been fine


Check all speaker wiring for shorts, if okay! there is a problem in the audio output stage of the unit or the protection circuit is not working properly. I would suggest a pro to evaluate.

Just bought a Sharp LED TV and there is a slight delay between hearing sound and seeing lips move. Have cable box hooked up to tv by HDMI and have cable box hooked to AVR (Harmon Kardon AVR125) by optical...


Hi if there is an optical out on the television i would use that direct to your Harmon Kardon AVR 125, the sound would be in sync with picture, as the source is the same.

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,
Sergey
