1. 从提供的log中看system_server并未重启，相关文件中的记录system_server启动次数的属性都1
[sys.system_server.start_count]: [1]

2. 出现大量DTC_display 报错，具体请查看dtc.log文件

目前，将这段时间的黑屏BUG做分类，如下：
1.屏端软件异常，电压异常、屏幕处于not ready状态等，需屏厂更新软件解决
2.主机端投屏ok，屏端背光未打开，主机端未做异常恢复机制。5.31合入代码解决。
3.no video异常，视频信号传输异常，该类BUG旧版本日志DTC无明显报错，5.31合入代码新增视频检测信号，并打印日志。
目前屏厂monkey测试出现2台异常，但现场未保留。正在让屏厂复现，并验证修改方案，预计验证OK后6.2号合入。

从日志中分析，该BUG为第1类。
目前5.31版本已提供VB给屏厂测试中，持续跟进屏厂测试结果中。

与118378为同件BUG：
该BUG需要屏厂更新MCU软件，非主机端问题。
