If a COF fails, it often loses its VGH or VGL supply. A technician using bypassing techniques might trace these voltages from a working point on the board and "bypass" the bad COF, sending the correct voltage directly to the panel at a later point to restore functionality. This involves carefully cutting existing voltage paths and "jumping" the connection to a new point.

The book skips basic component testing (like checking for bulged capacitors) to focus on complex "Display Problems" that typically result in a TV being scrapped. If a COF fails, it often loses its VGH or VGL supply

Source drivers manage the columns (colors and data), while gate drivers manage the rows (turning pixels on and off).
