Trackspot won't receive DMX

Ok guys here we go. I have two trackspots with the exact same problem. These Trackspots have the "red" dip switch boards. I will do my best to describe everything I know.

Good Stuff
1) The fixtures will power up with no problems
2) The fixtures will perform all of the self tests with no issues
3) The fixtures will "center" with all dips on and personality dip on.
4) I have replaced the 8 pin IC chip with one from a good fixture with no change.

Bad Stuff
1) When I run a DMX cable from my NSI ML16 to either fixture I get no response
2) As soon as I plug the DMX into the socket the fixture does not recognize the input nor will it reset.
3)When I try to run in master/slave neither fixture will respond as the slave.

I think there is a problem with the DMX connectors but I really have no idea. Any help would be much appreciated!

    You do have the Trackspots set for DMX operation, right? Since the Trackspot is an older fixture, the default protocol (all switches off) is Lightwave protocol, not DMX . . . .

    Yes I do have the correct personality protocal setting(dipswitch 3 & 5 on). I guess I forget to mention that these fixtures worked fine. I took them down after a show and when I put them up the next time they would not work. It just seemed odd to me that they both have the same issue at the same time while all of the other fixtures are fine.

    If the diode (2) is fried in the com link you will get as you described. If the locks on the xlr's are not done right you can get the same thing.
