It will either be a ground or the sockets if you have replaced the ballast already.Most likely the sockets.The stab locks can be bad out of the box.Either the connection is no good or oxidation has set in making it resistive.And you just can't see it until you break it open.The wire will have a green coating where it was in contact with the spring.I have pull plenty of hair out over this myself.
