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

    Same EXACT problem but on the AVR335. Worked fine for 6 months then went completely dead. Front panel does not indicate that anything is wrong. I've reset it without success. I'm guessing it's the thermal sensor screwed in the heat sink at the top-center. Anyone have any info at all on that sensor?

How do i fix a noise problem on 6.1 avr 135 ?same trouble occur on alls channels,a high frequency sound disturbing listening.neither inputsi used(cd-dvd-tape)


There are many reasons this may happen, but without having the unit on the bench, it will be hard to tell. It may be oscillating, which would make that sound. I worked as a Technical Support Specialist for Harman Kardon. If you are interested in repairing your HK, please visit my website at audioserviceclinic.com. Thank you.

HK AVR 125 display strobing and no sound, even in headphone jack


Hi...

Find someone that does TV or audio repair and have them open it up. A cable assembly may have loosened during the MOVE.

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.

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?

Harmon Kardon dvd5 player will not come out of the standby mode , will not power up.


hi lowone.

here is a review i got from or HK DVD5 users. Unfortunately HK cannot have the issue fixed over the phone, so the best way for you to resolve the issue is to bring the unit to an authorized dealer and have it repaired. a replacement is also possible depending on how well your unit came in.

...

I admit it, I am very partial to HK products. I own 2 of their receivers (one of these for 2 years, the other for 6, and they both

work beautifully), but as far as dvd players go, they have done a very shoddy job in terms of lasting power. The first unit that I bought lasted almost a year (to the day). Then one day, the unit wouldn't come out of standby mode, with a few dvds trapped inside. HKs techs couldn't help on the phone, and they had me drive down to New Jersey to an authorized dealer, who kept it for 2 months (these can only be repaired in CA at a specific HK repair shop it seems). After making a bit of a stink, HK sent me a refurbished model. I've used this one about 15 months, but now this one is starting to act flakey. The picture will start to stutter, and break up, then will stop completely. This is on pristine discs with no smudges or scratches. I have reset the processor, but this doesn't affect the problem. So now, I don't know how About Schmidt ends, because the player encountered these problems towards the end of the movie. Very aggravating. I spent about $500 for this, then had the long drawn out problems with getting the unit repaired, and when all is said and done, these played for about a year each before problems were encountered. HK definitely has to work on improving the longevity of their dvd players. Until then, I think I will shop for a different brand, since this one is on its last legs.


Hope this helps,

regards,

voodoo

Static and popping from Harmon Kardon AVR 340


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.
