JVC GR-D72U Microphone Replacement

Introducción

Sometimes a video will not be able to record audio or it could be muffled or scrambled. If you are sure that the problem lies in the microphone you should replace it. To remove the microphone you will need a Phillips #000 screwdriver, small plastic opener, and metal spudger.

This guide requires removing a lot of screws so it is important to keep track of which screw goes where. All screw heads are Phillips size #000.
