After a fair amount of time and headache, I finally got past my issues with the Neo not learning some of my Harmon Kardon buttons. When it was all said and done, I only had three buttons left to learn, the video 2,3,&4 buttons. I searched high and low on this site, and the net with no luck. I ended up getting the Pronto Editor program, grabbing it's hex codes for a similar AVR, using an Excel conversion worksheet I found on this site, and then applying these new codes (with some tweaking) with the Neo hack application. While it is fresh in an open window on my desktop, I figured this might save someone else a lot of time, enjoy!

Below are the IR codes for the Video 2, Video 3, and Video 4 buttons for the Harmon Kardon AVR320. You will need the Neo hack application to apply these codes.

Hi,
I've got an H/K AVR7000 and can't get any codes other then off and on to work, No volume, no vid-1 thru vid-4 or dvd, or 6 channel or dts etc............any idea's?

I can certainly relate, I actually had issues with more buttons than just the Vid 2-4 with my H/K learning. I ended up using the only H/K AVR code Neo provides, and tested each option. I was able to apply a few of those to buttons that wouldn't learn until I was down to just the Vid 2-4.

Here are some codes to try...

On - 0 f 6c 4 62 ab 14 3f 55 ab 3f 5f fc 42 c 0 0 0 4 0 40 44 0 0 0 40 44 44 44 4 0 bf 50 fc 42 8 bf ab bc f2 b 21 7c 3

Off - 0 f 6c 4 62 ab 14 3f 54 aa 3f 5f fc 42 c 0 0 0 4 0 40 44 40 44 44 0 4 0 0 44 0 bf 50 fc 42 8 bf ab bc f2 b 21 7c 3

Volume Up - 0 f 6c 4 62 ab 14 40 55 ab 3f 5f fc 42 c 0 0 0 4 0 40 44 40 44 0 40 4 0 44 4 0 bf 50 fc 42 8 bf ab bc f2 b 21 7c 3

Volume Dn - 0 f 6c 4 62 ab 14 40 55 ab 3f 5f fc 42 c 0 0 0 4 0 40 44 0 0 4 40 44 44 40 4 0 bf 50 fc 42 8 bf ab bc f2 b 21 7c 3

If you copy each of these codes and post them into Excel or Notepad, you will notice that when comparing each of these codes there is a series of numbers that begin with "0 0 0 4 0 40 44..." that are the only varying digits. The other digits stay the same as they define freq, etc.. related to the AVR.

If you have successfully learned some of your H/K codes, take a look at them using the Neohacker software. I don't know how much H/K varies their codes between receivers, but my guess is the middle digits which define the buttons are probably fairly similar (the "0 0 0 4 0 40 44..." digits). As a sample take some of the codes I provided above and try plugging in the middle digits into your already learned codes that define the AVR.

So for example for the Power On button, plug "0 0 0 4 0 40 44 40 44 0 40 4 0 44 4 0" in and see how it works. I hope all this makes sense, I formulated these theories while working on my solution. I learned a good bit about the breakdown of these codes from the Pronto2NEO Converter I found on this site under Files/Utilities. Good luck with this, I hope it works out!

Cool, thanks......Where can i get this neohacker software?
