Phenomenon: there is accompanying sound, the base color-red appears for a while, and there is a regression line. After testing, the voltage of the C electrode of the red video tube dropped to 20V, and the voltage of the C electrode of the green and blue video tube rose to 200V. Judgment: 1. The red tube is usually broken; 2. The picture tube is broken. 3. Other reasons. Start with the most common faults and change the view of the release tube. As a result, the faults still appear from time to time, indicating that there are components that are aging or have poor contact. After careful inspection, starting and touching, R515 is found to be de-soldered, re-welded, and the problem is solved.
