I'm having the problem where about 2 inches of the edge of the screen goes haywire and eventually becomes vertical colored bars, rendering that portion of the screen useless.  I know there's several others with this problem but I can't find a solution.  I did the self test check and the screen was black like it's supposed to be, but nothing displayed in that portion of the screen.  If my warranty is expired, there's nothing I can do?  Is there any way to fix it?
