Answer to "A1304 no back light after LCD cable replacement?"hello from Portugal :) HUGO.. well yours like my don't have lamp its LED so you will not find that extra lamp cable.. its all in LCD cable ..it appears that cables break internally make some short circuit and kill the fuse its a good practice to exchange the cable if that happens . if it was mine i replace the fuse, change cable and clean all the machine, and put some new heat past in cpu/gpu.... buena sorte...
