Connecting JVC Home Theater from Used Store: Subwoofer Sound & Power Light on but Incomplete Setup

Hello,
I recently purchased a JVC home theater. I spent some time with him to connect them and unfortunately I failed. I will add that the cinema is from a store with used things. However, the power lights and some sound from the subwoofer comes when I connect the cables to it. I have no idea how to connect this home theater. I hope that someone will help me, for which I thank you in advance and I bow my head for knowledge

So yes. From the "Front speakers" output in the amplifier you connect the INPUT "High lever" in the subwoofer. Then connect the two front satellites from the "To main speakers" subwoofer output.

You can also connect the subwoofer through the China signal sockets, then from the "Subwoofer out" output on the amplifier you connect to the "Low level" INPUT socket.
I highly recommend this option.

Other satellites connect directly to the amplifier, i.e.
Center speaker - Central satellite
Rear speakers - Rear speakers

And it was combined with a DVD amplifier.
You can do it through the usual "Audio Out" and "Tape" chinches in the amplifier.
Or via the "Digital out" optical cable - in this case you will have full 5.1 sound but the difference in sound quality will not be felt on this class of equipment.

I tried to explain the most "pathologically". I hope understandable

Kolibercio, you save my life and many thanks for your help You are my guru
However, I have another question. Is it possible to connect this set somehow to a laptop and play music from it using this set?

The TAPE inputs on the rear panel of the amplifier should work as an aux. You can't connect the computer through it.

So how well do I understand I will need an adapter?

All you need is a 2 x chinch (RCA) cable - a small jack, of course, like a laptop, it has a headphone output.

Thank you ladies for help The equipment plays quite nice
I just have to play the radio and it will be fine. Because the cables are properly connected only, I don't know why the radio is not looking for FM and there is no problem on AM. However, this can be a problem in the settings.
Thanks again

There is a connection of this type of home theater to the TV with such inputs with attached in the photo.

You can connect this TV and cinema with a TosLink optical cable.
Both devices have these sockets.

And some other solution because it doesn't work. It seems to me that an optician in a cinema should shine just as it is in TV. The TV cable is lit, the plugs are removed.

Optical output activated in TV settings? -> instruction
Cinema set to optical input? -> instruction

And so off the beaten track - the TV has a headphone output?

The tv has no output for headphones. However, an optical cable was enough and the amplifier should be properly positioned under the optics. The cinema will work right away. I just don't have time to connect the speakers because I have overtime at work ... I hope I can put it together before Christmas xD. Thanks a lot for the hints ?
