Ok, i know this may sound like a dumb question but, is it possible to replace a screen on a plasma tv? and are there any wholesalers in the edmonton area that would carry parts for my specific tv? you see, my tv screen had aquired a crack on the top left side from an airborn candle holder, and now when i turn it on the screen stays black, theres audio still, but no picture at all. is this even fixable??
