I'm having more issues with my ASI2600MC and the ASIAir Plus. I would start the autofocus routine and it would fail half-way through. If I switch to preview mode I get all white images and finally exposure failure messages. I have to power cycle the camera to reset it. I swapped it out for my ASI2600M using the same setup and exact same cables and no issues at all.
So I contact ZWO for an RMA to get it repaired and Simon (from ZWO) told me I have to test it with ASI Studio first? Really? Why? It's really not convenient for me to do this plus it's been raining constantly. Just want my camera repaired.
I don't think this is an issue as pointed out above me with half the pixels dead since this seems to be intermitent (however occuring frequently enough to make the camera unusable).
ZWO, if you reading this. Just give me an RMA before I take a hammer to this camera.
