Try unscrewing the flashlight head from the flashlight body and removing the LED lamp assembly. It is integrated with the reflector which can also be unscrewed from the lamp assembly if necessary. The lamp assembly makes contact through two springs that make contact with the flashlight body and it is possible it was not assembled correctly causing one of the springs to be distorted and not make contact. Failing that, the LED emitter assembly might be defective.
ni-cad or ni-mh rechargeable batteries all have charging cycle life and will fall in effeciency. in saying that, batteries used for some time will be not be as powerful as the new ones, and over or under charged batteries also wouldn't give you expected power.
i guess the CR123A you replaced is a new one, so it has the desirable voltage and current.
LCD itself and the driver actually do not require a lot of power, but the camera does, which draws away from the battery.
