Quick analysis...Before you start worrying about the Shadow Mask, make sure
all bridges have been crossed.;-)
Kevin...after a while you will be able to look at cracked CB damage and
before you even start, depending on number of connections, decide if you
even want to waste your time.
Considering your time, and having proper tools, scraping, soldering, and can
you guarantee it for your warranty.
Normally, on Toshiba, any drop will be around the flyback. If the crack has
gone beyond that..Do yourself a favour...let it go.
