Description
【环境信息】EE环境
【问题出现时间】：20230525 16点35分（ 第188次开机）
【前提条件】：车机上电（KL30ON ，KL15 ON，已连接中控和功放，可正常输出声音）
1.副屏16点15左右播放腾讯视频和中控爱奇艺视频混音，截取log后，进入QQ音乐界面
2.副屏长时间未进行任何操作（超过10分钟）
【实际结果】
副屏屏幕突然黑屏，点击屏幕不能亮屏
【期望结果】
副屏正常显示，无异常黑屏现象。
【备注】：
发生一次，杜（磊）工和高(平平)工有来现场确认。
点击有触点显示，只是屏幕不亮屏。可以通过投屏工具对副屏进行操作。
车架号VIN：HRYTTESTVINMGM400
中控端log可从云端获取，

请Display同学进一步分析

当前分析：
此问题疑似屏幕出现了异常。在问题复现期间，控制器没有控制屏幕display off，但整个开机过程中并没有发现屏端DTC错误。
1.从日志中看到第188次开机时间在15:48左右。log抓取时间在17:07左右。整个过程中开机次没有增加，说明系统不存在断电导致的黑屏。
//开机完成

05-25 17:07:06.957 9844 10216 I ActivityTaskManager: START u0 {cmp=com.tc.logclient/.LogClientActivity} from uid 10061
2.从问题描述的时间点来看从开机到抓取日志的过程中，控制器没有做过灭屏的操作。整个过程中，控制端认为屏幕的状态应该是亮屏状态。
直到17:02:44，人为在电脑投屏上点击了息屏按钮，控制器才对屏幕进行灭屏操作。随后点击屏幕进行亮屏操作。

下一步计划：
1.添加屏端和控制器的回读，心跳检测retry机制。明天开始联调。

- Status changed from New to RESOLVED
- Assignee changed from CD BSP-余霄 to CDTS_TEST 王成
- % Done changed from 0 to 100
- Root cause set to 添加retry机制
代码在105已合入
修改：
1.回读量灭屏背光状态，亮屏且背光为0或灭屏背光不为0时重新下发开屏指令
2.新增视频信号DTC，检测屏幕显示状态，异常做RESET动作
3.DTC中添加背光变化时日志打印

这个问题只是追加强化日志，没有实际解决，需跟踪并且和屏端联调
