MBD10 Users - Please help

Hello,

My MB-D10 has been giving me problems with intermittent functionality. The camera shows it as attached/not-attached/attached/not . . .

The default is usually un-attached and by reattaching it manually, I can get it to see it for a few frames.

I have tried all of the solutions recommended here* to no avail. In looking the unit over, I do see that one of the pins is noticeably lower than the others. Not having a unit to compare it to, I don't know if that is normal so I am asking any other users to please take a look and let me know if yours look that way. If it is not normal, then I am feeling good that it may be the culprit and I'll send it back for service.

Fresh batteries, voltmeter across the contacts to ensure full 12V charge, camera set to proper batteries, contacts cleaned.

I hope the pictures are self-explanatory, if not, just let me know.
