While the GPU is responsible for transforming mathematical equations into individual pixels and frames, a TCON takes the individual frames generated by the GPU, corrects for color and brightness, then sends out parts of the image to each individual driver at the panel's specific timing.
Considering this, how do I know if my T-Con board is bad?
Black Light Failure

Also, do LED TVs have T-Con boards? And these intermediary circuit boards are generally found in larger TV's, usually 40 inches and above. Now, we say "up" to the T-Con Board mainly because the T-Con Board is typically located on the top middle portion of an LED TV or LCD TV.
Moreover, what causes TCON failure?
Since the T'Con disperses the pixel data to groups of line and column dirve IC's situated on the outer edges of the panel, it is unlikely that more than one of these IC's would fail at the same time. Multiple columns of struck on or stuck off pixels are therefore, more likely to be the fault of the T'Con circuits.
How do you test T-con?
The best way to check is to begin with the LVDS cable from the Main to the T-CON. It will have a test point for the 12V to the T-CON. Look on the left or right side for 4 pins tied together, this will be the 12V test point.
