Sounds like it could be the link port yes. And if it is some error like 
this I don't think there is any reliable tests without opening it...
Have you dropped your calc with the link cord connected or something?
Or used it a lot?
Could be bad solderings at the link port, or maybe that the little metal 
thingies inside the connector has been bent, so that it has bad connection.
To open the calc you have to remove all screws, including the one holding 
the backup battery. (sorry, your calc will be reset during opening)
I find it the easiest to then crack it open at the top first, I do it with 
my fingers by pressing the front half in a bit and pulling apart. then I 
use the slide case in the crack, pulling backwards until it snaps up.
Not good to use screwdrivers or metal things, it could damage the case.
I have done it a lot of times, and the calc still holds perfectly together 
without any screws. (I don't bother to screw them back, is nice to be able 
to open your calc easily. And its a nice "party trick" during class ;)
If you aren't already classified as a geek before, you certainly will after 
at least :))

You could look for cracks in the soldering that holds the linkport by 
pulling a bit in it.. carefull though.
or just resolder them to be sure.

And all the usual precautions when handling electronics ofcourse like not 
touching anything you don't have to touch and stuff to avoid ESD.. but you 
probably knew that.

All this ofcourse break any guarantee you might have...
