故障排查
Troubleshoot
1.整列LED不亮。
如下图所示，列从左到右为Q1~Q24，若该列LED不亮，则检查对应的三极管是否焊接完好。
1. The entire column of LEDs is off.
As shown in the figure below, the columns are from Q1 to Q24 from left to right. If the LEDs in this column are off, check whether the corresponding transistor is in good condition.
2.整行LED不亮。
如下图所示，行从下往上为ROW0~ROW15，若该行LED不亮，则根据原理图检查对应芯片引脚是否焊接好。
2.The entire row of LEDs is off.
As shown in the figure below, the row is ROW0~ROW15 from bottom to top. If the LED is not lit, check whether the corresponding chip pin is soldered according to the schematic diagram.
3.单个LED不亮。
检查该LED是否损坏，可通过万用表（调到二极管档位）检测，红表笔接+、黑表笔接-，如下图所示。
3. A single LED does not light.
Check if the LED is damaged, it can be detected by a multimeter (adjusted to the diode position), the red test lead is connected with +, and the black test lead is connected with -, as shown in the following figure.
若LED可以正常发光，则重新用烙铁补焊该LED两端的引脚焊盘即可。
If the LED can emit light normally, use a soldering iron to repair the solder pads on both ends of the LED.
