Would incorrect polarity kill a screen?

Hey,
I was just wondering if a screen would be ok if I put my batteries in backwards. On the casio screens there is a fuse to bypass if I do it wrong right? Psone screens also have a fuse (I know from experience).
Thanks

yeah, it would most likely kill it

I guess its dead then. Does that mean the board is dead (good lcd) or the whole thing is dead?

There is probably a fuse somewhere on the power in line. Just follow the trace until you come to a square shaped thing, check it for continuity with a multi meter, and if needed jump it with solder and/or wire. If you have no luck with fixing it, could I have it (I would pay for the shipping)?

Well, there was no way to know if it was working before I worked on it so I guessed it was already dead. I don't wan't to mess with the fuse just yet because I don't even know if I put +/- in correctly. G-force if I don't figure it out you can have it. Aww crap I just threw away some boxes.

One of my poop egress friends came over, wander'd into my lab and started dicking with stuff. He took one sceen and pluged it in backwards and nuked an electrolytic capactior. It fried, but luckally i was able to fix it.
