Troubleshooting

Statistically, the number one replacement item on cameras is the lens assembly. Mostly because of physical
damage caused by either user carelessness or abuse. In many instances, the damage is visible but in other
instances, it may be internal and invisible. When no visible damage is noted, the technician has to determine if
the problem is with the lens or with the electronics controlling the lens.
? Look around the lens barrel lip or barrel sides for impact damage.
A very effective method of determining if the lens motors are working is to initialize the camera and listen to the
slight noise from the zoom and focus motors as they are turning. The motors will usually turn and make noise
even if the lenses are jammed. With some practice, the technician can discern the noises from each motor.
If noise is heard, it is a good indication that the electronics are working.
? check the lens cap switch first. If OK, the lens assembly may be defective. (It may also be caused by a
defective SY-68 board.) See Figure 8-2 for location of lens cap switch.
