Re: Strange issues with Panasonic NV-HS830
There can be ab issue with some combinations of devices where the suppression-capacitors - which form an AC centre-tap across the mains, with the centre-tap connected to the [un-earthed] chassis - inject noise-voltages - which can be significant - into the interconnections.
If the interconnections are hot-swapped [or swapped when the equipment is powered-up] it's possible for a significant spike to be fired into the active pins of the interconnects - the big issue here being that on the usual red/white/yellow RCA phono-plugs the centre contact mates before the screen - so any voltage-differences between the two devices get applied to the active components first when plugging/unplugging the interconnects.
The spikes can cause associated control-circuits/microprocessors to enter undesirable states - and/or permanent damage!
[I've known a rather-expensive DSLR camera be damaged because of this, when the owner connected it to his laptop and both of them were on-charge from their associated power-bricks].
