Plasma TV construction question

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.

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
(hopefully)
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 :
