3 lights is normal
You really don't want the LOS LED to light because that means Loss Of Signal.
It’ll never have all 4 lights on, its not supposed too.

The system can not see colour. The colours are only there to help/make it easy for people plug the cable into the correct sockets at each end of the cable ie plug the yellow cable into socked A and socket B.
