If you are experiencing any of these symptoms you most likely have a bad panel, NOT a bad Tcon board

-One side of the screen is darker than the other
-Horizontal line or lines appear on the screen
-A "dark" spot spreads across the screen

This is a common issue with TVs that use this Tcon board. If the TV's screen is defective and you replace the Tcon you will damage the new Tcon.
