AVR 3700 no sound

SOURCE: No surround sound

Hi,

As you already checked the speakers, the HK manual says to check if the audio analog chain is fine. That means selecting 6/8 direct channels as source and apply a sound source for each channel. You can use a CD and test each pair of the 6/8 inputs at a time or use the output from a PC sound card with a test generator software (some excellent free software available as from NCH swift). Adjust the volume and listen. I guess you will obtain sound from the right front channel.
If you have sound in all speakers at the end of the test it means all audio channels are fine end to end.
The good news according to HK manual is that you eliminated 90% of the component of the system. The bad news is the problem is in the DSP section. There are no instructions or tests for the DSP part so you will have to go to the service center.

Goodluck..

SOURCE: OSD not working (black screen)

Your 635 will not display the OSD screen through component. You must use either s-video or rca. It won't upconvert the screen menu this route.
I had one up until a week ago. There are two outputs on the back specifically for the OSD screen. I used a separate old 13" TV with s-video to do my setups. Hope this helps.

SOURCE: I cant get any sound out of my Harman kardon AVR

Hi! The rca output may be faulty causing it not to give sound to the speakers. If that will be the problem then you will have to have it replaced for it to work again. Hope this helps and have a good one!
