Introduction
One common failure of the ZX-5n is the pop up flash. The pivot holding the spring can break relieving the tension on the spring. When this happens, the flash will no longer pop up to its proper position. It may be possible to repair the existing part with epoxy but you can also replace it with a donor part from another camera or with a 3D printed part. A model for the 3D printed part can be found in the Documents section of the Pentax ZX-5n page.
