Please intimate exact model of Sony product that you are looking for instruction manual, so to provide you proper manual.
Thanks.

Basic checks first. Have you checked they are connected properly? Maybe used a different cable to check whether the rear cables are faulty? You may just have turned your system to 2.1 surrououn sound by accident or be playing a format that only supports 2.1. Check that in the system menu under dec. mode that if it is set to AFD STD that you are playing a DVD which shows can support 5.1 on the back of its cover. Also try running the setup manually and choosing your speaker configuration. Hope this helps.

Please let me know connectors color at back of unit to provide you info for speaker cables.

Same problem here!
