Samsung Laptop: Screen became black all of a sudden (PHOTOS INCLUDED)

samsung np sa 31

Hi guys, I'm new here and really hope I can get some help :)

I was using my laptop normally, I turned it off, by pressing the power button and then closing the lid if I remember correctly since I was in a hurry.

After coming back to the device, the screen just wouldn't turn on! It just stayed black.

I tried everything. Messed around with the BIOS, reconnected the LCD cable, repositioned the RAM sticks and tried to run it with only one of the sticks, removed the CMOS battery and then placed it back, tried to clear static via power button, and much more, INCLUDING buying a whole new screen! The same problem still persists.

The laptop is fully working when connected to an external display via VGA cable, you can see everything on the screen when you flash with a flashlight on it (same for the original LCD and the brand new one I bought).

I have no idea what's wrong. I fully disassembled the laptop and I will add imaged of the motherboard, to me, nothing seems out of place and no fuses are burnt (the heat sink was removed for the sake of the photo), but maybe you guys will know what to look for and I'm just missing something.

Thank you !!!

Dell XPS 13 9310: replacing cracked front glass on screen

Wed, 03 Jun 2026 10:11:58 -0700

Due to a recent drop, although the display is fine, there is a fine crack and small shattered corner on just the glass. I'm wondering if that can be replaced without replacing the entire screen and outer case.

Thanks for any pointers.

MSI GF63: Why are my graphics going in and out periodically?

Tue, 02 Jun 2026 23:35:35 -0700

GF63 Thin 9SC-614US-BB5930H8GXXDX10MH, it is GTX 16 series

I know this laptop is older at this point, but for a long time it went unused, and it has not been used heavily enough to be causing these issues IMO. Roblox is the main thing that runs. It was getting very very hot, someone opened it up and cleaned out the dust and reapplied thermal paste. Back when it was getting very hot, I'd notice that at its hottest is when the graphics would go weird. (it would just start losing details in the characters and room behind them... the CPU and GPU were getting up to 80-90*C, GPU was always lower but both high numbers like that and they would fluctuate a little bit as soon as I opened Roblox) Anyways that's no longer an issue, I use cooler boost through dragon center, and the numbers stay pretty "normal". But the graphics are doing the same thing. It's not the settings in the game, and it's not the wifi. When it happens, I will close the game and go back in and they will be normal again. But eventually it will happen again. I have updated my drivers, I don't understand why it's doing this out of nowhere.

HP Chromebook 14a-na0000: Chromebook hinge cover broken

Tue, 02 Jun 2026 09:19:44 -0700

I've had my Chromebook since June 2021, and a few days ago the plastic around the screen on the lower left (I think this is called the "hinge cover") broke, the bottom part detached from the screen (only at the left, not the entire thing) and eventually cracked completely off from the left side of the plastic. I didn't drop it, this just happened gradually I guess. At first I thought it was just cosmetic, but just now the screen flashed black for a second when I moved the computer - it isn't happening every time, in fact it hasn't happened again since, but I'm sure the issue will progress if I don't do something.

This is what I can see inside the plastic (if I angle the screen so it sticks out enough):

My question at this point is, if I made sure those little white parts on the outside were aligned right and pressed in real good, then used glue or putty or something to seal the plastic back up, would that prevent any more screen flashing or other issues with the screen itself? Can I even use those things on my computer? I don't know if the picture was clear enough, but I should be able to glue it without affecting the hinge.
