Perhaps it's time for a follow-up post.

So now I have two 622s purchased 8 months ago. I resoldered one pin on one, and the other hasn't failed. Repair was 4-5 months ago.
I've losened the HDMI mounting screw on both units and am careful to minimize tweaking the cable around (though the cleaning girl can get a bit ruff).
I still believe the tension on the solder joints is being caused by the mounting of the port to the back panel combined with thermal stress. It's not gonna matter if you ever touch it.
BobMurdoch, I believe that your boxes would do better with the screws losened.
I'd like to hear from others who tried a fix? If I remember, some resoldered, some losened the screw, and one put a spacer between the screw and the back panel (though it was after failure, and he didn't resolder).
I gotta think we'll be seeing boxes with redesigned connectors VERY soon.
