If the front slider on the camera is cracked or broken, use this guide to remove and replace it.
This guide is also a prerequisite for disassembling other parts of the camera in order to prevent damage to the slider, and to make dis-assembly easier.
Locate the 2 screws on the bottom of the slider.
Remove both screws with a #00 Phillips screwdriver.
Gently pull on the bottom of the slider until it comes off the lower track.
There is a little piece that connects the slider to the track. Be sure not to lose this as it is needed to put the slider back on.
Lift the slider up until it comes off the upper track.
The slider should now be free from the body of the camera.
