Needed an advice for a proper replacement

[AssassinNation]

Hello!
I had this - LG HB954PB 5.1 home cinema system for quite a while.
It is a blu-ray player, which comes with 5 speakers and a subwoofer that connect to the player(I don't know much, but I think this is called a blu-ray player with a built in amplifier...).
My player died recently and after checking in the retailer, LG said that it is unrepairable and irreplacable.

Now we are heading straight to my problem:
My speakers are not dead, they are very good so I don't and can't right now replace the whole cinema system. So I'm asking you if there is a device that can act like my player did, that has 3-4 ohm connections for my speakers.
You can see the connections of my speakers on the photos provided.

PLEASE HELP ME A.S.A.P.

What you would need is a surround sound receiver.
One like this may handle your 4 ohm speakers since it is rated for dynamic power into 4 ohms.

but you would also need a separate mono subwoofer amplifier that can handle 3 ohms because all AV receiver assume that you are using a self powered subwoofer. Home theater packages usually put that amp in the main unit. You could probably replace the passive sub you have with a self powered one for about $100.
