I have a HP Spectre X360 13-4116dx and the screen is flickering on/off at about 1 second intervals. I linked a video of it below. The behavior is a little inconsistent but it still occurs using the windows basic display driver and when I boot into a Ubuntu live usb. I think that it's a hardware fault but my question is: is it the display panel? could it be a power supply issue? I'd be willing to replace the panel but I'd like to be sure that'd fix it before I spend $150+ on a new one.
