Comptar 5.5 187 motor tv zoom lens. no picture.

Question

I recently had to replace the camera location using the above lens with an exact replacement camera. I had to relace the plug to the camera from the lens as I bent the pin. The camera zooms and focus when power supplied but the irus does not open no picture. I am losing my shirt on this job, can these be repaired. any thoughts on why or if I am doing anything wrong. thanks in advance.
