Description

【环境信息】EE环境
【问题出现时间】：20230527 17点40分（ 副屏第212次开机）
【前提条件】：车机上电（KL30ON ，KL15 ON，CANoe的E2E工程发送电源模式信号powermode=local on，已连接中控和功放，可正常输出声音，副屏以太网和WiFi都是已连接状态）

1.在17点15分之后就一直在做中控的电源管理测试（发送BDCM_Powermode信号并进行IDCM的KL15 ON和OFF切换），未对副屏进行任何操作（包括未对副屏的KL15进行操作）

【实际结果】

副屏突然黑屏（黑屏时间可能更早，只是17点40分才观察副屏）

【期望结果】
副屏超过10分钟无操作，显示屏保界面。
【备注】：

可以通过WiFi连接adb，可以使用投屏软件进行投屏到电脑，通过电脑端下滑显示控制中心，点击控制中心的息屏后，再点击副屏屏幕，副屏恢复亮屏。

车架号VIN：HRYTTESTVINMGM400

中控端log可从云端获取，

2.
复现视频中
①屏幕硬件显示是黑的
②投屏是正常显示画面的
说明这个不是上层画面显示问题, 麻烦重新确认下，谢谢

和屏端异常相关,明天出VB给到客户进行验证

请跟踪屏厂VB 压测出现黑屏问题

#8 Updated by CD BSP-余霄 about 2 years ago

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3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。
