This section of the manual is the "X-ray vision" of the repair process. It labels every test point (TP) on the circuit board. For example, if a TV has audio but no backlight, the manual guides the technician to the specific pins on the LED driver board to check for voltage output. It provides the exact voltage values expected at these points. If the manual says "24V expected" and the multimeter reads "0V," the technician instantly knows the issue lies upstream in the power supply, not the LEDs.
