I found that the barrel (black plastic on one end and white on the other) had gotten turned and was not lined up. Two pliers with one holding the black side (flat part) and the other on the white plastic got them lined up and then it would push all the way into the lcd side of the housing. I also tried putting the barrel into the lcd housing and turning it with one plier while pushing. I believe that worked better. Sorry to necro this but hopefully it will help some frustrated soul.
