Hi, yep that RCA end with the plastic center is bad. If that was the end pushed inside the RCA input on a receiver then the metal center piece is stuck inside that female rca input. If that end in your picture was pushed into the female RCA plugs inside the turntable make sure you check that RCA plug and remove that metal piece from that rca plug if it's in there. You will probably need a needle nose pliers to get it out. I would then throw that set of RCA cables away and pick up a new set. I hope this helps.
