Samsung PN50C450B1DXZA Can't Post

Samsung PN50C450B1DXZA took a lightning strike and would not power up. I replaced the Main Board and everything is working properly now. Except I now have red sparkles or haze in the center of the screen. I searched for the cause and found that it could be a firmware issue. I upgraded the firmware to the current version from samsung and it seems to be worse than before. Could this be a Sustain board issue or any other board issue for that matter??

Try adjusting the VS to +205v and VScan to-178v, this should fix your issue.
