KGFN,
I have a lms 350a and the same thing happened, found it to be the gray connector
in the cord that goes to the module and the one that goes into the module itself,
My Solution, cut the gray connectors out of th middle of the cord and hard wired them,
took the connector of the module and cleaned the pins and put a little bend in them to make better contact and put it back together and it works fine. Had a problem on the module with vibration after that and it would go in and out, but some rubber strips fixed that.
