The only thing I can suggest is to first get access inside to the logic board and inspect the 8p8c jack (RJ45). Is it a through-hole type or surface mount (SMT)? Do the joints appear to be soldered well or are they "cold"? I would check all that out with a continuity tester on a multimeter, just to rule that out.
It is possible that maybe it got zapped real good with a voltage spike, either lightning or through a faulty surge protector, ethernet hub/router, etc. If that's the case, then the port may be dead as a doornail. You'd have to replace more than that jack to get it working; maybe the whole board.
Let's also think about the drivers/extensions. Which OS? Are they all installed properly? Are they intact or corrupt?
Just thinking outside of the box as far as what it could possibly be.
