Can you say life is sucking right now?

Wow. That is the stuff nightmares are made of. The main reason plasmas cost so much is because of the difficulty and precision in making the screens, the actual electronics and materials are all rather inexpensive.

I assume the crack goes into the image and it does not work at all?

I honestly don't know where Cracked plasmas go, as I have never had the displeasure. I have seen cracked ones, but I run the other way.

You have to tell us how this crack came to be. Please.. We need to know what happens.. I'm sure somebody else will have more useful information for you, but it's kinda like a car wreck for the rest of us...
