Yeah, Geert, It's very strange that got into this state indeed and the stranger thing is.. i'm still pluggin' it in, every time i'm gonna play it without resistance and getting the green light right away... and yes i was aware of the arrow as soon as i saw the neutrik's so no forcing or something like ever happen.
The other one i fixed with some hot-glue was straight as far as i could tell only easy to push back in it's hole and pushing it back, it didn't lock like the other 4 do, only after seeing the photo my self, is when i saw the bending.
Still haven't opened that one cause as i said, if i didn't come to this thread i wouldn't have noticed or inspected... never had problems with connection from the first day, two months ago!!
My believe is that those pins never had a locked sitting in the first place.
Have disassembled now the second one (on photo) and by this one, after pushing the pin back in it's place, locked!!, only had to bend it straight again and now is like it should be, locked in it's place... the connector can't be plugged other than with the arrow up so it's not possible to bend a pin like that (tried with only the jack without the cable in it, the front part of it, and it can only be plugged in one and only way!!)
Not giving an orange light, i suppose it passed the check on Eigenlabs, but really wasn't 100% and if i got it right, those pins only contact to the shielding, which i suppose don't give any major error if not connected, except with strong magnetic or electric disturbances, whilst the other four are for the actual data stream.

Btw, sorry Ace if i'm sort of hijacking your thread... and FYI, i've experienced what you were telling about the screwing tight.... not only the outer jack goes in only one way in the TAU, the inner component with the pins goes only in one way in the jack and also the last clamp on the cable, to assure it doesn't turn around by screwing the back tight on the front... if that last one isn't in his locked state, the inner work can shift back and you can get the orange light pulling it a little.
