LCD panel failures
Some LCD panel failures could possibly mistaken for T-Con board issues. Other than damage to the LCD glass, most panel failures are isolated to a particular area of the screen. 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. The same applies to a single row of lit or unlit pixels. The T-Con simply cannot cut out a single line of information.
