Harmon kardon avr 25 II

I recently got this harmon kardon avr 25 II from a friend who said it worked perfectly, when i hooked it up to brand new speakers i got no sound, no matter the input. no tuner, no phono...nothing. when i put in headphones and turn the volume to it's max i can barely hear a whisper but that's all the sound i've ever gotten from it....any ideas?

    i am having the same problem - when i turn the unit on it starts this fast clicking thing where it seems like it is powering on and off very fast. Eventually it slows down and finally is 'on' but the time to get there is longer and longer.. It's a power supply issue,. ,I'm pretty sure, but all the fuses look good. Thanks.

    I had this problem and it was intermittent and it was only with one channel. I would push up and down on the volume knob and that sometimes would make it go away. I opened up the top and found a wafer board that the volumes rheostat is mounted on. I put a little wood wedge under it to create the same pressure as pulling up on the volume knob and this fixed the problem for a while. Eventually I started to get a fast clicking sound whenever I'd turn on my receiver and the problem would come back intermittently again. The receiver would come on after several clicks. The problem got worse. It began to take longer for it to come on. Now all I get is clicks and the amber power light does not go to green. I still haven't solved this.

Hello. If you are hearing a fast clicking sound, it could be 1 of 2 relays in the unit. When you first plug the unit in, push the power button, you should hear one distinct click. Within about 5-10 seconds, you should hear another click. Is it this second click that keeps clicking on and off?

You need to take the fuse out which is closest to the front of the unit. it will reboot the whole system. These fuses are small, but, seem to hold on with a blast of the volume. For some reason the amp has an auto shut down. The pre amp needs to be rebooted. I found this out by trial and error with the fuses

Not much as far as worth....awesome equip but everyone wants those home theatre kits now at lower costs....this used to retail for about $770 when it was new to the best of my knowledge...and does the fast clicking sound continue or quit after a little while?

When I turn power on I hear a sharp fast clicking sound.
Additionally, any idea what the receiver is worth?

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

No sound from tv to speakers


i assume you are hooking up from tv to receiver with an optical cable? Check the settings on your tv. Most tv's have a setting to turn on/off the optical audio output

My receiver doesn't have a dedicated subwoofer output, can I still hook up a subwoofer? I have a harmon kardon avr 25


That would depend mostly on your subwoofer. There are some that slave off the front left and right speaker outputs and still pass the amp's power to the Front Speakers. That would be the only way that would ensure volume control.

Otherwise you have to feed a self-powered sub from the Tape Outs but that won't allow volume control from the H-K.

Harmon Kardon AVR 230 produces no sound and no monitor out.


you do not have +17v and -17v on transformer board the top two fusible resistors are blown and the cap between them needs to be replaced as this cap probably shorted and caused resistors to blow. easy fix

Harmon kardon avr 25 ii


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!)

Good luck.

No sound?


Hi Sicarius

I know it sounds dumb to ask these questions as you may or may not have already, but have you checked that any tape monitors are turned on. Another thing to check is that the "prein preout" jumpers are in place on the rear of the unit. If they are not there, just use a spare rca lead to jumper them. Let me know how you got on. Good luck
