It's a self aligning connector, it's supposed to have a certain amount of "wobble" to allow it to mate up when pushed into the sled.

If yours is the player which had the dim display (I'm not in the office and so can't check) then this has been fixed. One of the capacitors on the display board had broken down in some way and meant you were running at about 1/6th normal brightness. Only ever seen this on one other player...
