    I have a 63" NEC plasma in for repair, and after getting it going (bad
    MOSFETs in PSU) I noticed a darkish blob about 3" * 6" in the top lefy
    hand corner. It looks exactly like the soot that is liberally coating
    the rest of the electronics, except that it appears to be on the
    inside of the front glass cover. Is it possible to separate the front
    glass from the rest without destroying the integrity of the tube ?.

    There is a sheet of glass on top of the plasma tube. If it's between
    this front glass and the plasma tube, you can fix it. If it's inside
    the plasma tube, then it's obviously not fixable.

  3. Yes, but I don't see how such a problem would likely occur inside the
    tube since it would have to extend over hundreds or thousands of pixels
    which are all separate from each-other and sounds like they are working.
    So, it must be between the tube and the front glass.

    Yes, Sam, that's what I figured as well - it got in there somehow, so
    there's gotta be a way of getting it out - (obviously it cannot be
    within the plasma
    tube itself). My question is really about the removability of the
    cover glass (without
    destroying the plasma tube). It looks like this :
