HDCP has been around since 2000, and yes, it occasionally does cause issues, just like Macrovision did before it. To me, OCR means Optical Character Recognition, so I’m not sure what you were saying there, but it does sound like your equipment got zapped.
As a shot in the dark, try unplugging power from everything, reseating the HDMI cables, and then plug it all back in.
If there are any HDMI switches or splitters being used, try bypassing them.
My First Express 3700 from 2016 would randomly have HDCP problems – maybe 2-5% of the time. I’ve never seen one since I replaced it with a 3941 from 2021.
