Hi there, RikSound1. The problem is the C657 capacitor, located on the DSP PCB. It's a 0.047 farad capacitor, 5.5V. You can either replace it yourself, or just hand the info out at your local repair centre ! It will fix the problem for sure, i have fixed that problem already. Thanks, cheebster.

hey i also had this problem, i don't know the name of these but they are basically plugs that you have to block output from the front rear and center speakers of the white/red cables... sry for bad description but its on the left side when looking at the back of the receiver, while all of the other speaker wires should be hooked up to the right with the twisting knobs... it took me forever to find this out but yeah it was a simple fix

Usually Humming noises come from frequency interferance. In this case it is being caused by your input sources. A smiply solution is to replace the cables and or seperate the source cables away from any electircal cords or sources.

Try hooking up a yellow video wire from the back of the AVR 225 Monitor out. Should be at the end of the 7 or 8 yellow video ports on the back of the stereo. Next plug the other end into a yellow video in on a t.v. Get your remote, (Harmon/Kardon) and make sure the t.v. is on the correct video input and hit the OSD(on screen display) button on your harmon remote. There should be a setting in there that says VFD under ADVANCED menu option that allows for turning the front of your stereo lights on and off and dimming them half way also. OFF/HALF/FULL are the 3 options I believe.
If this doesnt solve it your display may have crapped out on you.

I upgraded my HK AVR 20II and ran into the same problem when I tried to hook the old unit up out in my garage.
Luckily I remember that on the rear there is a pre-out RCA port (L/R) and a Main-In port that are intended to be to/from an equalizer/amplifier. These come jumpered out of the box, but I had been using an equalizer so the jumpers were long lost.
Assuming you also have no amp/eq you are using, just connect the Pre-Out to the Main-In using a standard M/M RCA cable and you will be in business. (turn the volume down first!)
