Unable to power on
Nothing happens when i push the power button. Possible faulty switch, or does it have a fuse? Tried finding a repairer, no luck. Does anyone know how to open the unit? It appears sealed?

Hi @rob47744
Here's a link that provides a lot of information regarding Harmon Kardon Soundsticks.
Scroll down the page to find the This Article Continues... section to find links that have a lot of information regarding various sections of the speaker system.
Regarding not turning on, have you checked that the adapter is supplying 16V DC on the output plug of the adapter? If it does then once you have opened the speaker then you may have to check the components around where the adapter plugs into to see if there is a fuse or perhaps some other protection component located there.

No lightson during pressing main power/volume button. Any idea of what is could be before I start replacing things on the board? :)

If you have a DMM (digital multimeter) maybe you should test things before just replacing things e.g. is the switch working OK, is the power cord OK and is there power getting to the board etc.
You could check if there's a fuse or other protection device at the power input that may have blown or if there's other components that look heat stressed or damaged etc.
Just what I'd do if there's no service manual or schematics available.

I have almost the same problem - when I push the power/subwoofer volume button, the blue light comes on and I can adjust the sub volume.
But as soon as i stop pushing it pops out, the sound disappears and after a few seconds the blue led dims out.
My question is this: Does this point to a faulty powerswitch or to some sort of circuit failure beyond the switch?
I'm thinking the switch may be simple push-button action switch (not meant to keep the circuit closed once the button is released) and the problem is somewhere else
