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?

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.

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.
