Power surge on my laptop panel screen when recording

OBS cannot damage the display panel. It’s just some app displaying some stuff, the same as with every other app. The panel got damaged due to some unknown reason, and by chance OBS was running at the time. There is no connection.

Shutdown Windows, switch off your laptop, disconnect every cable including power cable. Let it rest 5 minutes, then turn the laptop back on. Try to get into the laptop bios, usually by holding down the F1 or F12 or DEL key while switching it on.
If the display is still defunct, and you’re not even able to display the system bios, you probably need a replacement.
