Hardware Odd Flickering/Glitching on Nintendo Switch Screen in handheld mode, Help Needed.

[OhItsSlick]

So I’ve got a switch that has this odd flickering and glitching on the screen. The switch doesn’t dock so I can’t figure out if it does this in docked mode. I’ve replaced the ribbon cable FPC connector two times and both times seemed to actually lower the intensity and frequency of the glitches. Now the switch works fine for a bit or it flickers as shown in the video. Has anyone experienced this before and figured out what to do? Thanks I’m advance.

If you shine a bright flashlight onto the screen, you can check whether it's the screen itself or backlight.
You should see the nintendo logo vaguely if the the screen itself is ok.
Opening it up and checking the power of the backlight might be more accurate of course :

Maybe there is something wrong with that circuit powering the backlight.
The leds in the backlight likely pulsate with a high frequency.

For anyone who stumbles upon this post and experiences flickering on the screen in handheld, this issue was caused by the LCD FPC connector. One of the pins was bent so proper connections weren't being made.
