Repair method for non-obvious broken line in double-end line: according to the broken line rule, the first side line at the broken line is usually at the inner turning. Check which leg the first side line leads to the left side of the line: first, find the first side line at the corner, adjust the multimeter to the buzzer, connect the red watch pen to point A, and "sweep" all the legs of the left side of the line. Find out which leg of the first line leads to the right end of the line: at this point, find out which leg of the broken line leads to the right end of the line. The above mentioned is the upper edge of the search method, the lower edge line also has a place of easy break line, that is, the second easy break line, its search method is the same, no longer repeated here. Some lines have several layers, and each layer has two upper and lower side lines. At this point, two side lines of each layer must be found. For example, if you have a double row of lines, there are four sides to look up. In most phones, only one of the edges is always cut, which means that if you find one of the edges is broken, there is no need to check the rest.

The continuous maintenance method of the products of the manufacturer when the double end of the line breaks down: this fault is characterized by a display when the cover is opened to an Angle and no display when it is fully opened. It indicates that the line is not connected when it is lined up, and when it is searched by the previous method, it is often found that the side lines are all connected, and no point can be found to break the line. Check which leg of the first side line leads to the left end of the line: first find the first side line at the corner, and then carefully scrape the insulation off with the blade at point A. Then, the multimeter is adjusted to the buzzer. The red stylus is connected to point A, and the black stylus is used to "sweep" all the legs of the left row of lines.
