I have a 50 in plasma Sanyo, I came home one day and there were a couple black line vertical lines on it about a pixel in width I learned on line if you have a scratch on your tv (son said he used his fingernail on it) you can use cardboard paper to eliminate scratch. At first this seemed to work the black line was being broken up and dissipating. Although the next day had an ugly oval in the middle of the screen about one inch high and one inch across that had dots in the middle of it and the oval at the bottom had vertical lines looking like drips coming down from it. I tried a dead pixel fixer and it seems to actually be fading and blending in more with the colors behind not black dots any more but multicolored. It is very frustrating any help would be appreciated.
