Question about Harman Kardon AVR 510 Receiver

1 Answer

Intermittent breaks/pauses in sound

I have an Harman Kardon AVR 510 which had been working fine until recently. Every now and then (maybe once or twice every 10 minutes), the sound on all speakers momentarily stops. It is very much like what you would get when there is scratch on a DVD, causing the DVD player to skip. At first, I thought it was a problem with my DVD, but that problem happened on multiple DVDs. Then I thought there was a problem with my DVD player, but I've been getting this same problem with other components as well (e.g. listening to stereo and 5.1 feeds from my digital cable box). I'm not certain about this, but the front panel lights seem to flash (on and off) during these sound outages. Does this sound like there is a problem with my receiver?

Re: Intermittent breaks/pauses in sound

Yes. I had a H/K reciever in my shop last month with a similar problem. It turned out that it had micrscopic cracks developing on the motherboard, which caused it to shut down as they heated up. It wasn't repairable.

The receiver must KNOW it has a sub and you must decide how bass is managed among all your speakers and set up relative levels.

This is clearly a manufacture defect right off the assembly line. From your description you have a serious intermittent problem with the AVR unit when it comes to selection and other choices and it will only get worse, I strongly suggest you return the item in favor of another.

I have a Harman/Kardon AVR 325. Left speaker not working with TV

How is TV audio (from the cable box) getting into the Receiver? If digitally, you wouldn't be missing any one channel on a connection malfunction, you'd lose them all. If analog, swap the channels around to isolate the problem (and reconsider using digital).

No sound - distorted sound only out of the left speaker

Maybe the audio amplifier IC are fried by the power surge

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.

Harman Kardon AVR 40 no sound

Check the fuses - there may be one inside the box as well. May also be a bad transformer. You can get a multi-meter at Home Depot and lookup how to check the power at the transformer.
