just disconnected old light fitting. tried to connect new one but does not work. now also all the lights in the house dont work plus the tv aeriel signal has gone. the old fitting had 8 connections with a loop. the new fitting has just got live neutral+earth on it. where the mains comes through the ceiling there are 5 sets of wires:- 3 with L,E,N, 1 with L,L,E, and 1 with just live+neutral. do i need to connect the new fitting using a loop connection which was originally there? HELP!
