Windows 10: Laptop Screen Blue Tint when plug/unplug USB's

Hi, this is my first post in TenForums!

My laptop is acting weird since a couple months ago. The first time was when I unplugged my external hdd. I noticed that the screen colors turned a bit colder, some sort of blueish tint appeared. On all this time I've noticed that this happens when:

• I plug/unplug my external hdd/mouse from the usb ports. (Sometimes this also happens when I click the option to Eject Mass Storage from the Safely Remove Hardware option in the System Tray).
• When I'm playing games / closing games.
• If I close the laptop and the screen turns off / sometimes this fix the issue and colors goes back to normal. Sometimes don't.
• Sometimes, when I turn on the laptop it starts with the blue tint and after a period of time goes back to normal by it's own.

I opened it up, it wasn't that dusty. I cleaned it up. Unppluged the monitor cable. (I havent touch the graphics card yet.) I already have all the drivers up to date. What could be the problem? I think mybe it's something related to the voltage on the usb ports but I don't know. I din't see anything wierd when I was inside.

Here are my laptop specs:
ASUS K556U
12GB RAM
NVIDIA GTX 940MX
Windows 10, 1809.

I never showed any examples of my problem. See the attached images. Those are black and white images, but on my screen they are black, white and light blue-ish.

I connected the laptop to my tv and it shows the right colours. (black and white photos are now correct, not with that blue tint). (Before this problem my screen had this blue tint for circa 10 seconds, after that it changed to the right colors.)

Hi guys, I'm back.

I brought the laptop to a PC shop and they told me that the motherboard was damaged. The best option was that I should buy a new laptop, which I did. I bought the MSI GL62M 7RDX (1050 GTX, 8gb ram). Guess what, this screen has also the same blue tint!!

Now this is a brand new laptop so I think there can't be any problems with the hardware. I updated the Nvida drivers etc, didn't work. Unbelievable. How to fix this? Any suggestions? I just don't understand I have this problem again with a new laptop.
