Thanks to all who have responded... based on many replies, I think I
understand everything well enough to ask better questions:

Yeah, silvery, not flaky. So that's a good thing

Ok, what exactly does it mean for a heater to be arcing? It starts to glow
then stops, then starts, then stops.
Also, Several people have have used intermittent in this context and I'm not
quite sure I understand... it is intermittent in the fact that it
intermittently starts and stops glowing...

I have my TV closed again, but when I open it up again I want to have a list
of all the things I need to look for and what to do about them. So far, I know
I need to look for bad connectiions, broken 'pins', to make double sure the
little mark is silvery instead of gray. However, all the wires and soldering
seemed to be in tact, of the connections I could see everything was fine. BTW,
I'm relatively (70%) sure I know what parts are what based on descriptions
here, but does anyone know of a site with pictures that labels different parts
so I can get a better idea of what is what? Thanks.
