I recently had to replace 5 fuses on one of F16v2rs which is why I asked.  Have swapped strings between port 7 and something else.  Just use test mode to check.

Output #7 shares an "output" chip with channels 5,6 and 8. Usually, if that chip goes bad, all 4 outputs stop. It's possible that just #7 died. On the F16v2 Red (I have one), those are socketed chips. There are four of them across the board. If you really, really want to check, swap chips carefully. If the problem moves, then you need a new chip. If it stays at #7, then look on the bottom of the board for bad solder.

I have had just one output go bad when I accidentally shorted the data line for one output.  The other outputs on the quad driver chip still worked fine.   This was verified, as you said, by swapping chips with another bank.   Easy to test and easy to fix with a new chip in the socket.
