Having an issue with my Legion Y740-17irhg booting up fine but the screen doesn't come on.
I've plugged in an HDMI and display port to an external monitor and it blinks like it's about to pop up then doesn't.
Windows boots fully and I hear sound.
I've taken it apart and see nothing out of the ordinary like a popped cap or burn spots on mobo.
Anyone else have this issue or heard of something like this?

Try to do an ec reset?

Not sure the right method to do so. Disconnect battery/cmos and then push novo button? Can't find anything on the correct method

Nothing...didn't work. Still booting up fine and can hear windows start but still no video. Super frustrating...
