See attachment. It's the pin (red) which had short to ground (green). But it seems to be only that pin, not the same in the other side. It's either the CC1/2 or SBU1/2 pin. why only one is shorted I don't know . But could explain why the cable only works one way with 14.5v.
I have a suspicion that a bad cable has caused a fault inside the port, which then caused malfunction in u4700.
With or without the port connected there is no short on C4706/07. Maybe the red pin is SBU1/2 and not CC1/2?
For moment the cable functioned the opposite way around (mentioned above) but then went back to the previous way around. It's never worked both ways so far.
What circuitry is in these ports? It'll be a while until I receive the new one.
Cheers
