Phil, Tri State Module rebuilt it, I get all my modules from them, strange
thing is, the STK had not
been replaced, Tri State overnighted a chip for me but I still would like to
know how the IC
caused the symptoms I was getting, I received one reply from another tech
that said he had seen
this before, I guess we`ll never know, Larry E
