This usually happens when a 'Picco' fuse is blown. There are several of them. They are small, skinny fuses that look like resistors. The one you are looking for should be close to the power supply and located on the green circuit board. You must use an ohm meter to figure out which one is burnt out. It takes patients,but that stereo is worth the hassle.

AVR-520 shuts off after 10 secondes


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Looks like the Power relay is switching off and on by itself. Chances are that a power capacitor might be going weak. Get in touch with a Harmon technician to fix this.

Harmon/Kardon SoundSticks 2, Power adapter?


If you go to the Harmon/Kardon website, you can find where to buy replacement parts.

http://www.harmankardon.com/

Select product support on the front page, then go to parts.

Then select your product as Harmaron/Kardon SoundsticksII and select your country.

Hope this helps,

Nathan.

Need a replacement power cord for harmon kardon sound sticks II


its not that expensive for a power cord. they are running on 12v so you go and buy a 12v power supply with a jack that fits the speakers or you can just find a power supply at home if you have one that is 12v

I have a relatively new (less than 3 months old) Harmon Kardon Receiver HK3490. It turns on but immediately turns off. You can hear a clicking sound like a breaker is disengaging. The problem started...


It is a relay clicking. You will need to obtain a schematic to troubleshoot this but they are available online. The protection circuits have been degraded from the short circuit but it is still alive and the discrete components are easy to replace. I used to use Sam's Fotofax but googling your HK model will get you alot of results. Harmon Kardon is a great brand and definitely worth fixing. ~Steve Medley

Harmon kardon avr 125 shuts down


If you want to fix it:

It must be a contact problem arount the power switch, power cable, fuse or the condensator area.
Maybe you can se a black color on the board.
And checking the solderind points with a magnifyer can help too.

Thats all from that distence.
