Backlight is flickering, possibly damaged internals?
I power on my Chromebook, it seems fine at the bright white boot screen, but once I get to something dimmer (Discord window, wallpaper, anything dimmer than pure white), I notice a rapid flicker on the screen. The backlight never completely dies out, but the flickering is an eye strain and a huge annoyance. I already tried this guide in an attempt to get at the ribbon cable and nudge it back into place: Lenovo N22 Chromebook Screen Replacement
But now…I think I've done something horribly wrong. I tried to follow these steps, and made it as far as step 2. I have an N22 Touch rather than just the N22, but I figured that besides the touch screen they would be pretty much the same on the inside. But once I tried to lift up the keyboard, and felt some resistance, and found that in the top-right corner (by the power button), there appeared to be a piece of metal with a screw attached to the underside of the keyboard. When I tried to loosen this screw, it didn't budge. Possibly stripped? I can't lift the keyboard at all. Help!
Ist dies eine gute Frage?
