HK AVR 645 7.1-Receiver Turns off when sound starts to come through

I have the HK AVR 645 7.1 receiver. I have never had a problem with the receiver before. I have owned it for about a year, purchased from the HK ebay outlet. I have just moved and have been setting it up again. I currently have an XBOX with cables (for video) and a fiber optic cable (for sound), a blu-ray player with HDMI, a satellite box and a nintendo wii with cables. I had previously been using a TV with HDMI inputs and had no issues, but now I have a TV with DVI. So I purchased a HDMI to DVI cable to run to my TV I have 2 HDMI cables running in. The HDMI to DVI running out to my TV.

First problem is that when I try to turn my Blue-ray player on, the sound keeps swithching on/off. When I go into OSD, the setup keeps switching from HDMI/DVI to Optical every 10 seconds or so and then flips back and forth from HDMI/DVI to Optical and back. Any ideas?

Second (and biggest) problem: When I have everything hooked up, I turn the power on and everything is fine, but when I turn the sound up (even any sound), the receiver turns off. When I turn it back on, the minute sound starts to transmit, it instantly clicks off again. There is not excessive heat, all plugs have been checked and are in securely. Only thing that fixes it is when I take something off…so far, I took off the Fiber optic cable and it worked. Then a few days later I put the fiber optic cable back on, but took off the HDMI from my blu-ray player and it worked. Yesterday, tried plugging everything in again and it shut off again when sound came through…

Any idea what I’m doing wrong?

Hello, I didn't end up fixing the Blu-ray issue, but the TV issue was caused by just inverting the positive and negative cable going into my speaker. Odd enough, instead of just not working, it just flipped the entire system off. I can definitely see that that could be the issue, another one I thought of is, at the time I didn't realize that DVI doesn't play audio, only video and I didn't have a optical cable connected. I decided to avoid the hassle, sell the TV and purchased one that has HDMI. Muuuuch better.

Did you figure it out? I bet your problem is the same as mine NOT HDCP complitant.... its gettting a signal from the bluray that can not be accepted... research HDCP compliant... my ONKYO does the same thing...

I own a HK 130 and i gott no sound. it workt when i shut it off bute whene i started it i gott no sound plz help me


HK's must be programmed to output sound. It's probably back in the default mode and you need to go thru the menu for setup of sound output.

How do I hook up a turntable to a Harmon Kardon AVR receiver? Can't find correct inputs. Thanks


A 'generic' turntable and a 'generic' HK AVR?

"PHONO" is the only designated connection on an audio device that is literal and exclusive. Nothing but PHONO will work right on it and old-school turntables would require it to preamplify the tiny current produced by a Phono cartridge.

If your unit doesn't have a PHONO connection AND your TT doesn't have a self-contained preamp you will have to get a Phono Preamp to connect between the TT and any Line Level input, like Aux.

Hi, You might want to run your ps3's hdmi into your hk, as I'm sure it has hdmi inputs. Using your hk as the audio /visual switcher may resolve this issue-and by the way the hdmi cable has audio built in. I hope this was of some help and thanks for choosing FixYa, good luck Prodzilla.

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."

HK AVR 120 (left speaker not working)


Hi, your analysis are right, your speakers has no problem, the problem is in your receiver.
there are several factors that affects it, try some troubleshooting: and answer this questions:

1. During this event, what is the source of your INPUT audio signal?
Have you tried to replaced your RCA cables that connected to the source of your receiver?

If YES, then problem really exist in the internal system of your receiver. may be you have overdrive your receiver unintentionally, which cause the Power Amplifier to malfunction,

On this event, I would suggest that you bring your receiver to it's Service Center for repair,
This problem needs technical troubleshooting of a qualified technician.
