Warranty report and teardown: Viltrox FA-D10

The Viltrox FA-D10 is a 95 CRI, adustable-color-temperature, 800 lumen LED panel the size of a smartphone, with USB-C power and an internal battery. Mine failed after a minor impact, so I contacted Viltrox via Amazon for warranty replacement. They didn't ask for the old one back, so I took it apart....
