HISENSE 58 inch android tv

Everything was working fine and then I went on vacation. When I returned every time I turn the TV on I get picture sound black screen nothing picture sound black screen nothing and it keeps doing that even when I change channels except sometimes it'll sync with the channel.

It is as if it can't sink with my 4 ktv properly. If I hit the inputs button on the television remote and recent lect the H DMI one port that corrects it.

Why would this suddenly start happening? I have tried 3 different H DMI cables

Thank you for any thoughts or suggestions on how to solve this
