  • EDIT: also before starting any of this, unplug the camera and check voltage between GND and VCC on a powered up board. Check if the voltage seems at all plausible to power up the camera. Usually it will be 3.3V or 5V. Does the board by itself show any signs of life when powered on?

    The connector type is probably JST PH 2, but to confirm that you’d have to provide it’s dimensions. If the pins are falling out on their own, it would be wise to replace the plug. Terminals look fine.

    If you can’t disassemble the camera, then well… You might have to take a risk.

    Usually, but not necessarily, black wire is GND, red VCC. Assuming they are, you can plug those two wires alone and attempt to power the device on.

    Next you can switch your multimeter to DC voltage measuring, apply black probe to GND and try applying red probe to green and blue wire terminals. On LED wire there should be no voltage present (close to 0V), and on video signal wire you should be seeing some weird low voltage, possibly changing depending what the camera is looking at.

    This is of course all under the assumption that power wires were guessed correctly. If not, it may release it’s magic smoke.
