Question about Harman Kardon HK 3380 Receiver
Was working fine, I relocated unit and had sound from only one speaker (lead came loose from terminal) so shut unit off, reconnected and no longer have FM (AM and other inputs OK). Tried 30 minute off and the "mute" button reset while off but no luck. Fuses look fine (and the white noise volume does vary with volume control) and no bad smells or visual defects. Any ideas?
Faulty or missing FM antenna connection?

SOURCE: 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.

This is what's in the AVR7000 service manual:

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:

Check your audio settings on the main menu of the receiver. The audio input should be set to "auto" Next, make sure you don't have the unit in "6 channel input" mode or "direct" mode. This is usually a small button on the front panel. If you check all this and you still have a problem, post a comment and I will help you troubleshoot some more. Hope this helps

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,
