In the last picture, note the IC on the left hand side of the picture…. this is a SSM2017 mic preamp chip. To the left of it there are two large capacitors, they are 100 microfarad and with a working voltage of 63V. It’s most likely that one or both of these are faulty. They should be replaced with new. Most likely that will fix it, if not, then change the SSM2017 as well.

Dont forget that you need to cover up the light cell if you are trying to operate the VC3 with the top cover off! 😯

The ground being disconnected on the XLR would most likely cause severe hum and possibly also stop the phantom power from working.
