If the back is not latching, it could be caused by one or two problems. First, probably the back is bent and the latches are not lining up. Close the back until the latches should be touching and look closely at the contact point. Lightly flex (bend) the back to give it more of an arch until the latches line up. NEVER BEND THE BACK LATCH WITH PLIERS. Latch is tack welded on and this technique (aside from being wrong) may break the latch off. Other reason back is not latching could be because the spring that pushes the latch down under the top cover is missing. If this is the case, camera is tampered and was not reassembled correctly.
