Recapping my parts of it - on my 14 month old Vero V:
my remote is not responding at all - repairing has the blue light on for 30 seconds
my external USB2 port seems to be working fine
my USB3 port has power, but loses it if I jiggle my USB power meter in it a bit
I may have had my longish TV tuner plugged into the USB3 port at times, so perhaps that has applied too much torque to it.
Would it be appropriate to open up the Vero V, resolder the USB3 port, and inspect the board under a microscope looking for cracks/dry joints etc? If so, are there any guides to disassembling the V, or any tips?
So I was answering your question and saying yes, the USB3 does have power - but it appeared to be intermittent. That it went away when I moved the USB power meter made me suspect cracks on the board…? And yes, reseating the remote dongle might indeed be the fix for that (not that I recall any rough treatment of the V that could have dislodged the dongle) - but presumably it wouldn’t explain the tenuous power connection for the USB3 port.
Given the above, my best idea was to open things up and have a look - but if you’ve better ideas on how to proceed, trust me I’m all ears thanks!
