Question about Harman Kardon HK 3375 Receiver
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.

This is what's in the AVR7000 service manual:
Subject: Backup Memory on AVR/DPR/HK series receivers.
In the event of the complaint: “the receiver is losing its memory (any programmed system settings)
when the unit is turned off, or after the unit is unplugged (briefly*)”:
Check and replace:
Location: Front PCB
Description: 0.047 Farad 5.5v capacitor
Part number: # P10790-ND or # J3432147324X
I'm having the same problem and this is how far i got so far. I don't kwow how to get and replace this part.

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.

Testimonial: "cheers, have a good year."
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,
