Summary0001820: [Smart][ATV10][VCS] The black screen is showing after auto reset
DescriptionHi kerwin.

After auto reset, a black screen is displayed.
After the symptom occurred, it was recovered when the HDMI cable was removed and inserted.

This symptom does not seem to occur on regular TVs, but occurs when a monitor or HDMI splitter is connected.

I checked the log, but it is expected to be caused by HDCP authentication failure as shown below.

Hi Jerry.

I have tested your test FW with monitor and HDMI splitter.
It seems this issue has been fixed.

Before commit to bitbucket, could you please share your modification?

Additionally, this FW seems fixed mantis 1821 issue also.
If you have fixed this issue, please share your modification as well.

Thank you.
