you've obviously hit all bases except for the chandelier body. take it apart carefully with the power OFF and check those connections. not sure how they're connected together - maybe crimp on wirenuts or twist on wirenuts. may be soldered (???) the zip cord that goes through the 1/8th pipe may look good. best to check out with an ohm-meter. check from one wire end to the other with meter set on ohms RX1. check the individual bulbs with the ohm meter set on RX1. read right across the lamp base center contact to the screw shell.
