thachphamduong

Today, I just plugged the SD card into the screen and found that my screen had a problem with no backlight and no communication at the UART ports.Can the admin provide me with the circuit diagram of the DMG10600T070_A5WTC monitor so that I can determine whether the T5L chip is dead or not?

您好，附件是原理图，请查收。另外，没有背光，是不是下载的时候没有的按：断电-插卡-下载完成显示“END!"-断电-拔卡的这个顺序操作呢。

您好，我们推荐的工作电源是12V 1A 的直流稳压电源，您的屏幕之前是正常的吗，现在连接电源一点背光都没有吗？
