Question about Harman Kardon HK 3375 Receiver

I have a Harman Kardon HK-3375 stereo receiver. I

I have a Harman Kardon HK-3375 stereo receiver. I cannot get it to power on. I believe the power switch has gone bad. Does anyone know where I might find a replacement power switch. I came up with the diagnosis by plugging a small appliance into the outlet on the back of the receiver. When I press the power button the appliance has power for about 3-4 seconds then goes off. It seems to me the power switch is immediately switching off. Any suggestions will be appreciated. My electrical knowledge consists of changing light fixtures and such. If changing the switch is a matter of splicing a couple of wires and screwing in the switch button I believe I can do that. Thanks

A power switch either works or does not work. It does not power on and then mysteriously power off like yours is doing.
You have some sort of power relay that is being powered off after a few seconds.

I would check out the power supply for your anomaly. And no, it is not a simple fix like you are capable of performing.

SOURCE: can I conect harman Kardon avr 230 to apple tv

Yes, although it (AVR) does not support HDMI only component video.

Connect the audio to the receiver and the video directly to the TV if you have inadequate video inputs, or want to take advantage of the HDMI.

I believe it is actually a memory capacitor that has to be replaced. It is soldered directly into the board and requires quite a bit of know-how to replace.

Hope this helps,

Hk 3490 receiver on protection mode....what it means and how to correct that


You can try a factory reset after checking your speaker wires for shorts. The procedure is in your owner's manual. This will most likely not resolve your issue. If you need further assistance, or would like to inquire about repairing your Harman Kardon, please visit my website at audioserviceclinic.com and contact me there. BTW, I worked for Harman, as Technical Support for all Harman, JBL and Infinity products.Thank you.

The fuses should be checked, if okay! check speaker wires for any shorts on the back, if good! the driver and audio outputs, " transistors and ic's " need to be checked by a serviceman.

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."
