I bought an I cinema i-HD901 system and it does not have any power cord. All there it has are wires. what do I used- to power the speakers and the subwoofer. I would like to be able to play this surround system through my TV. It only came with 5 wires is that enough?

probook 470 G1)
the PC has only 1 jack for output. called line out /phones.
sadly I can not guess what this home cinema system is at all
no makers name of
home cinema no model name or numbers for home Cinema

so no answers possible
speaker system with built in power audio AMP is needed.
The below 6 are called CONNECTIONS

1. USB system ,
2. or fiber. TOSLINK.
3. or 3.5mm line out jack call "Phones" jack tool (or 5.1 Surround)
4. or wifi sound
5. or Blu-tooth sound.
6. coax S/PDIF

your PC can not drive directly any wired speakers.

wired means 2 wires to the raw speaker cone coils..
it needs to have an amplifier to the raw speakers.

no home CineMA, TOLD NAME OR MODEL OF PHOTOS OF IT Present.
just buy USB sound BAR at Wal-Mart and be happy?
plug it in see it works.

to do 5.1 with 3.5mm color jacks that you do not have
you need 5.1 sound USB dongle.

The curse of some all-in-one HTIB's is proprietary color-coded speaker connectors where cheap plain old lamp cord or speaker wire would do.

check wiring on speakers it sounds like you have some wires touching together somewhere or you have a bad speaker.

Google "Samsung SWA-4000" The HTz310 is wireless "ready" only. You'll need to purchase this unit for about $100 to make your (Rears only) wireless.

you need an optical cable going from the TV to the home cinema for an audio output, it worked for, had the same problem!!

There is other Cinema Surround systems that use the same 8 Pin setup Aldis had one retailing at £49.99 and there are plenty on E-Bay www.eserviceinfo.com will provide schematics for these systems so you can select the right one.

i have the same problem. haven't tried the fix yet, but someone recommend connecting the two pronged power cord to an adapter that switches it to a 3 pronged (adds the ground prong). i guess the adapters are less than a dollar and can be bought at most places.
