So, I know that speaker and light magnets donot damage LCD like they
used to dmage CRT's. However, my daughter a mere 2.5yrs old, took a
magnet and was able to make entire area on the screen go completely
black. First question... anyway to repair it? second, how could this
happen?

Is "entire area" the entire screen?

If it's just a portion of the screen, you can try this site.

Stuck pixels can sometimes be unstuck. But DEAD pixels are black, and
they aren't coming back.

you need to find and replace the failed part.

maybe saturatiing an inductor in the poswersupply causing some part to fail.

No, just a portion at the bottom of the screen...

This is a LCD TV not a computer monitor. Anyway, if black is dead,
then they are certainly dead. Just lost like $400 worth of TV :(

Any idea why this would happen?

Maybe heavy pressure bruised the screen. You may as well try gently
massaging the damaged area. I have a few dead black pixels scattered
around my LCD monitor, and neither the rapid color switching exercise
nor massaging has fixed them.
