Hi just got a ViewSonic N3752w 37 in. LCD tv from a friend with a pretty banged up screen. It has several lines in the picture as well as some blackend screen. Any idea of whether it is repair able or how...

It sounds like the LCD panel is badly damaged, if that is the case, it will not be worth it, sceen is the most expensive part of the whole TV, you may be able to sell each parts of the TV on EBAY. Post the pictures of the screen will help.
