Introduction

This guide shows how to replace the flash assembly on a Nikon Coolpix B700 when the bulb stops working.

We have to separate the Nikon Coolpix B700 camera starting with the back frame, then we can open the camera and take internal parts out. After that, you can see the flash unit from inside and replace it easily. Make sure to remove the battery before beginning the work on the flash unit.

For the old flash unit, you can see https://www.epa.gov/recycle/electronics-... so you could recycle
