Just wondering: have you identified the exact cause and reason of these random shutdown issues, which have happened on the AX860i (and the AX760i)? Or you're still in the process of understanding it?
Considering the description of the behavior, it looks like something not so easy to troubleshoot - it's not so easy to replicate, as taking the cables off and back on seems to remove the error (at least for some time). Doesn't look like a faulty cap or bad component from what I'd understand...
So I'm quite curious, if/when the root cause has been found, what was really behind this? Maybe some weird DSP feedback behavior which, when unlucky, would go in a resonance/diverging loop?
