The "no signal method" for color TVs was adjusted to the midpoint of the week and has been recognized as the "best plan." This method has proven effective in various types of color TV repairs. Non-I2C bus color TVs produced in the early 1990s and earlier often suffer from capacitor oxidation, which reduces their capacitance and causes tuning issues, affecting the viewing experience. Many models have different images and accompanying sound-detection circuits, making it difficult to remember all the detection points (AFT voltage output pins) when adjusting the midpoint. Therefore, this "quick monitoring point monitoring table" was created, providing great convenience. I am now sharing it with my peers.

In Issue 8 of 2002, we published an article by Mr. Zhou where he emphasized in bold: "Adjust the two midpoints repeatedly without signal until the AFT voltage reaches its maximum value. At this point, adjust the image midpoint; then adjust the AFT midpoint to bring the AFT voltage back to 6.5V. At this stage, the AFT alignment should be correct." While repairing a JVC 7695 TV, I applied the core concept of the AFT midpoint fully, but the voltage was less than 6.5V (actually 7.2V), yet the fault was resolved. Mr. Zhou's statement about setting the AFT voltage back to 6.5V serves as a demonstration. However, the same type of integrated circuit may have varying AFT voltages across different models. Thus, the AFT output voltage is also listed in this table for reference during midpoint adjustments.
