Question about Harman Kardon AVR 340 Receiver

1 Answer

All sound just dissapeared

We have had our HK AVR 340 for a bit over a year now. The other day while in the middle of a DVD the sound went completely dead. At first we thought it was the dvd player, but after trying the radio and ipod bridge through it we still could still receive no sound at all. Has this happened to anyone else and how was it fixed? We are worried it will cost more to fix the problem then it would be to buy a new one, but with it being only 1 yr old we are a bit annoyed. Thanks

Hi. We have a Harman Kardon DVD and AVR and a Proline TV. When playing DVDs the sound from the AVR is not playing all tracks (usually the voice track is missing) - just background music and the odd door...

Your HK DVD probably has outputs for left and right audio and video (possibly color coded red, white, and yellow). These should connect to the corresponding DVD (or VCR) inputs on the rear of your AVR. When you play a DVD with your AVR set for DVD/VCR input, you should hear all of the stereo audio (there are no "missing tracks"). Next, review your speaker connections. They should be connected + terminal to the corresponding + terminal on the AVR, etc. One or more speakers may be connected backwards. If your AVR has speaker system A B provisions, be sure that speaker (system) A only has been selected.

Fiber Optic input

No gots. The 3485 is pre-digital stereo-only.

From the manual, page 19

"You may have observed that the HK 3485 is not equipped with digital audio inputs or surround sound decoding. If you prefer the complete home theater experience, you may wish to consider purchasing a fullfeatured Harman Kardon AVR Series audio/video receiver. However, we hope you will find that using a DVD player with the HK 3485 in smaller settings, such as a bedroom or den, surpasses the audio performance of most televisions, including those with onboard stereo speakers."

Harman kardon avr 140 - all displays work but no sound

I have an HK AVR140 all of the displays work, even shows when a digital connection from the Blu-Ray player is connected but no audio comes from the speakers! I found some information that HK does not have DC protection so when there is a problem muting Circuit is initiated on the main Amp. I called HK and they want me to send it in to a service dept that is not close at all. Any ideas? Or is there a way to by-pass the muting circuit somehow?

Humming sound (speakers)when HK AVR is powered up.

In my case the buzz was only on front speakers. There are 3 capasitors (100uF/25V) very close to the cooling ribs of 3 regulators in the power supply. In my case the C922 was bad.

Static and popping from Harmon Kardon AVR 340


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.
