I got my hands on a Rode NTG 4+ shotgun mic two months ago, charged it up, tested it a few times and was quite satisfied with the quality and build. Then I took it out to prepare for a film shoot a month later (yesterday), and found that it wouldn’t turn on. I charged it for hours, and tried again, but it refused to turn on. Does anyone know what’s going on here? I turned on Phanthom power of my Zoom H5 and the mic worked just fine, so I figured it must be the battery’s problem.
