Hello all, this is not my panel, but I'm curious about this type of
thing... wonder if any of you could lend a hand. This is what we're
dealing with:

As you can see the FFC has been torn off completely. With hundreds of
connections broken, there is no way to resolder this... my question
though is this: are all of those connections being terminated at the
silver block?

The silver block is a driver IC.

It was my understanding that all the connections at the
sides of an LCD panel were the ground connections, which run through
those FFCs to those grounding blocks which contact the metal housing of
the LCD panel. Am I mistaken?

Yes.

Would it be possible to ground all
those broken connections with one mass block directly on the LCD panel?


Yes, you can ground all those connections, but you'll end up with a thick
white bar across the screen! The silver block is one of the ICs which
drives groups of rows on the display. Without it, whole section of the
display will not work at all.
