I left it hooked up permanently - with input power connected - but not playing anything. It was very hot to the touch, and after a few days, it burned out!?!?! Why did this happen? Wondering, Denny

As long as your speakers are 8 ohms there is no reason for the amp to overheat. I would say that the amp was defective.

Exact same thing happened to me. I am in the process of shipping it out for repair. The unit is of terrible construction and the electronics flaked. I actually got a sub -woofer and wireless surround speakers for my TV which are 10 times better.

I have the same problem and unfortunately have not been able to play music from it either. Maybe we can get an answer from the makers on what we might be doing incorrect.

Sorry to be so long, but while the problem seemed to clear up, it suddenly developed the hum again. I have a Technics receiver with a phono output, so I have the turntable set to Phone Off. This worked until today, when it suddenly developed a hum, and when I tried to reconnect the wires the white wire produced a pronounced hum and the red wire produced an explosive pop. I played it this afternoon without incident, and have played it for hundreds of hours since last summer, but today the hum came back with a vengeance.

Mine showed up dead right out of the box. Plugged it in and turned it on with nothing connected but a voltmeter. The light lit up on the switch, but it had no output. I didn't want to open it up and tamper with it , so I just returned it and bought a better power supply. Read more reviews and you will see that others have complained about this supply burning out in short order at moderate loads.

This is not a question. You overheated it. Use a lower power for a little longer and you will reduce the likelihood of overheating.

Left mine playing its games until it was "Dead" flat. Rapid charged it via usb until it said it was full and then reset the time and date. Its behaved perfectly since!!! Odd but it seems to have worked! Good luck to all :0)

I honestly never did do that My pop has told me that you never connect everything to one unit for the fear of electrical damage that could happen so I advise getting PC speakers or better yet there are phono jacks I've seen on a PC system and two bookshelf speakers great sound and the cd burnt with the pc equalizer in it it sounded as if you're in the studio or there in concert so I hope this has helped you and wish you the best. By all means contact me about this Bud Lucas yerington nv

Kerwin, the answer to your question is yes. I started playing my usb and then unplugged the unit. When I plugged it back in, it started playing again on it's own with out me doing anything. PS Be sure to move the selector knob to usb. Just tried it and if you don't move the selector knob the usb just flashes and doesn't play. So move the knob to usb. This happens to be a great little unit. :)

This hasn't happened to me, maybe your power or negative source came loose. Check those connections .

I have played the unit for a good two hours with the battery. I almost always have it plugged in when I view it. I would see about returning the battery, or getting a new unit. Thats what I like about Amazon, I have never had a problem with a return or replacement.

My apologies for the long time to respond to this, this is the first time I get asked a question through Amazon. Anyways the power supply worked great for me but the problem could be from the power source or the speakers. So try to test your speaker with the same power supply at another location in your house or a friends house maybe with a portable mp3 player. Also if someone else has the same speakers borrow the power adapter or swap your friend's speakers from the monitor just to test it.

I don't know how did you plug in the speakers? It has 7 separate amps! Just be careful about its high-current capability, thats causing the over heating!

Yo, Mr. Lee, I'm very surprised to hear that your SoundSticks II "died" on you in such a short time frame. I would hope that Harmon Kardon took care of you. Please post a follow-up so that we other SoundStick investors see how customer relations works with this Co. Mine work splendidly tho they too are only a couple months old. Hope somebody took care of you.

I called customer service and returned mine for a refund. They were super nice about it! When I received mine and went to plug it in, it wouldn't even power up. I explained this to the customer service representative, and she couldn't be nicer to help me return the item! I don't know if your problem is similar, but I ordered a portable Jensen model with my refund money, and it works great. I hope that helps!

Nope it is the exact reason I trashed it. Mine also kept restarting after I would press play from a pause. Cheap interior parts.

I have no problems with mine. I would check for a loose connection or possibly the plug to Wht ever your running it to may be worn out
