Description

环境信息】EE环境
【问题出现时间】：20230531 21：00-20230601 09：00
【前提条件】：副屏上电，中控已连接
功放已连接 声音输出正常，开发者模式已关闭，无任何第三方应用
【操作步骤】
1.上传【adb push blackList.txt /sdcard】文件

2.adb shell "monkey --pkg-blacklist-file /sdcard/blackList.txt --throttle 500 -s 1234567 --pct-touch 35 --pct-motion 25 --pct-appswitch 30 --pct-pinchzoom 5 --pct-trackball 0 --pct-anyevent 5 --ignore-crashes --ignore-timeouts --ignore-security-exceptions --monitor-native-crashes --pct-syskeys 0 -v -v -v 12000000 >/sdcard/monkey.log 2>&1 &"
adb shell "sh /sdcard/monitor_monkey.sh >/dev/null 2>&1 &"
【实际结果】
1.早上来到之后副屏黑屏，中控无法唤起
【期望结果】
1.monkey正常运行，副屏功能正常，无黑屏、冻屏、花屏现象

【备注】：由于开发者关闭adb无法来连接副屏，无法虚拟投屏
【当前开机次数】：143
【应用版本】：
【硬件版本号】：

VIN:HRYTTESTVINMGM401
【中控版本号】：03.02.0086.C102

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。

刘强已到达客户现场

针对no video signal黑屏问题已有两方案，会提供VB给到那边测试
方案1
START_PORT_A与START_PORT_B进行RESET操作，并重新初始化加解串驱动

方案2：
检测到no video信号，进行灭屏、亮屏恢复
