Hi Paul, in brief:
1) Yes the TED manages the keyboard too, then it "could" be responsable of the trouble;
2) The metallic case is used also for cooling the IC then, once substituted with a new one, it it suggested to reinsert the metallic cover. (Or at least to refresh it by a fan or other mode for a few minutes of the test).
Let me remember you that once extract the suspected fault TED, you have to put it into the new machine to test it (and not to put a new working TED into the fault machine). This avoids that possible fault circuit burns the working TED.
