Blurry screen (LCD or logic board issue?)

I got this Macbook Air for repair and I'm still not a 100% sure if this is the LCD problem or logic board problem.

Watch here: https://www.youtube.com/watch?v=oym6NBeN...

Everything is blurry and it's like the frames do not refresh and stay there longer. The effect is worse when the display brightness is low (shown in the video)

Customer told me there may have been a water damage on the keyboard.

External monitor does work normally.

What I already tried:

  • I cleaned the motherboard with isopropyl-alcohol
  • reconnected everything
  • opened the electronics under the display and wiggled with cables (no clear image)
  • re-installed mac os

Nothing of the above helped and I'm inclining to think it's more likely a LCD issue. Can I be more sure before ordering an replacement?

Also the two white dots on the screen suggest a mechanical damage?

Thanks for any tips.

Lets inspect the LVDS connector on the logic board. With the battery first disconnected take a sharp zoomed in picture of the connector with the cable installed as well as with the cable disconnected and one of the cables end showing the pins post all three here 기존 질문에 이미지 추가하기 so we can see.

Thanks Dan, I've uploaded the pictures. This is the best I can do. I think the connector looks fine.

How does the solder joint side look? Post that if you can.

Looks ok too. I added the photo.

At this point the logic board looks very clean! I don’t see any signs of damage so I don’t think you have a logic board issue from the bottom side. You might want to double check the other side.

I do feel the issues is within the display its self.

I did clean the logic board from both sides so that's why it looks clean. Some of the contacts looks orange instead of the silver but I think it looks more like a humidity issue then direct contact with water.
