    I found out my mother in law dropped the remote but put the batteries in the wrong way, the speakers are harman kardon as well as the dvd player, I bought them as a home cinema package.

    Yeah I'm trying to go through via the OSD button but this does not bring up the master menu as it should, the speakers are compatible they are HKTS 8 which I got when I bought the home theatre package, could the problem have been a power surge?

Do you have a poltergeist turning the batteries around on your remote, or did someone play around with the receiver and its settings while you weren't around?

If the receiver doesn't recognize the speakers (what brand/model, just in case this turns into a hairball?), I'd crack the manual and go through the entire speaker definition and setup.

BTW: conventional speakers only use analogue cables. Why was that worth mentioning?

    Brand and MODEL of the speakers? If you bought them as part of a home cinema are they compatible with THIS receiver? Better yet, sometimes Fixya forces you to choose a model that isn't exactly right. Can we believe the receiver is Harman Kardon AVR 235?

    So, the remote WAS handled by someone other than you. Human error frequently precedes sudden disfunction of something. I still suspect a setting got changed.

    Did you go through the speaker defintion and setup yet?

    Perhaps it needs a reset...

    Processor Reset

    In the rare case in which the unit’s operation or the displays

    seem abnormal, the cause may involve the erratic

    operation of the system’s memory or microprocessor.

    To correct this problem, first unplug the unit from the

    AC wall outlet and wait at least three minutes. After the

    pause, reconnect the AC power cord and check the

    unit’s operation. If the system still malfunctions, a system

    reset may clear the problem.

    To clear the AVR 235’s entire system memory including

    tuner presets, output level settings, delay times and

    speaker configuration data, press and hold the Tone

    Mode Button5buttons for three seconds. The unit

    will turn on automatically.

    NOTE: Resetting the processor will erase any configuration

    settings you have made for speakers, output

    levels, surround modes and digital input assignments,

    as well as the tuner presets. The unit will be returned

    to the factory presets, and all settings for these items

    must be reentered.

    If the system is still operating incorrectly, there may

    have been an electronic discharge or severe AC line

    interference that has corrupted the memory or


    If these steps do not solve the problem, consult an

    authorized Harman Kardon service center.

Do you know if the harman/kardon avr125 reciever is 3d capable?thanks

Actually Home theater sound, is 3D. (Three Dimentional) Your receiver, using surround speakers reproduces 3D sound.
i.e. It is Left to Right, and Front to Rear. Thus it's 3D. If your get a 3D TV, your sound will be just fine because it doesn't come from the set. The sound SOURCE is the DVD player, CD player or Cable Box. If you use digital audio outputs (optical cable or orange colored RCA cables) from these items connected into the Harmon-Kardon, your will get the full Home Theater sound. The Harmon Kardon does not have HDMI inputs however it will not need them for the purposes of sound. Your Receiver is a high quality unit. If you want the thrill of 3D TV, go ahead and get one. After you have set it up, if you then decide you want to go to 7.1 or some other SOUND upgrade, go ahead. One thing you should know, is that there is not a whole lot of audio quality improvement available after 5.1. Unless you have a very large living room. The real quality counts when choosing the speakers and sub woofer that go into the system, not the amount of speakers you have.
I have done a number of high end home theater installations and the experience of hearing the systems (mostly 5.1) has been a thrill for the owner.
I hope this helps you,
Best Regards,

How can I get my Harman Kardon Soundsticks 1 to work on my PC?

The USB version of the soundsticks was specifically designed for the mac and they worked just by plugging them in and then telling the system to use them instead of the analogue outputs. Unless someone has produced drivers for Windows XP for these speakers I think that you will probably not be able to use them.

Harman Kardon AVR 154 OSD setup screen wont display

It will only display via component. Your HDMI firmware is either 1.1 or 1.2 and has HDCP issues (High Definition Copyright Protection) it's a firmware problem that has been fixed on all new receivers, not just a HK issue, all receivers! the new version 1.3a and 1.3b have fixed the issue. Unfortunately you cannot update the firmware on the receiver. Hope this explains it for you, sorry! Lot's of angry people out there!!! myself included.

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.
