May pull apart the beast just to see if there is any obivious internal fail - else see if ZWO say send it back to us for a repair.

I run a total of four ZWO cameras on three side by side or piggybacked Williams Optics refractors - my two cooled cameras are both powered by the same lab power supply - voltages measure with two multi meters at the power plugs ends that attach to the camera. They both use the supplied 2 metres ZWO USB 3 cables to connect to a high quality, powered USB3.1 hub that connects via a high quality 3 metre cable to the astrolab PC.

I tried swapping power supply cables betweem the cooled cameras - with either the 1600MM-c works fine but the 071MC-c Pro next to it heats up rather than cools.

As stated no software changes in 6 months bar a Windows 10 Service pack upgrade the other day. Cameras tested in TSX, APT and SGP - all show the same thing - which matches what the driver is reporting.
