Red Snow on black areas of the LCD screen

Hello,

last week my MacBook Pro 13" fell on the floor and got a hit on the side of the LCD screen.
Now the LCD screen is showing a sort of red snow (like the snow on an untuned tv) on the black parts of the screen. As far as I can understand it's either an issue of the LCD, the motherboard or the cables between the motherboard and the LCD.

What do you think it could be? I am going to order the parts in order to do the repair myself but I want to be reasonably confident of what I need to replace.

Cheers
/Luca

It sounds like your pixels are dead or faulty in that area due to the impact. Pretty sure you will have to get it fixed.

No! It has nothing to do with dead pixels.

If you draw on the screen a black square the "red snow" will follow the square. Dead pixels are stuck in the same position.

My question is very simple. Is it a problem with the LCD or the motherboard?

Yuppiiieee!!!

Found the problem! 🙂 I opened the MacBook Pro and noticed that it was just the connector linking the LCD to the motherboard slightly unseated.

tighten the connector a bit and now everything is fine 😉

I have exactly the same problem...but I have absoloutly no idea what is wrong. Can you tell me how you opened your MacBook and where the connector is? I don't want to risk breaking it....

Thanks.

The disassembly procedure is different according to the MacBook model you have. There are many guides around that you can consult in order to open the machine. You can search with "MacBook disassembly" and you will find many pages. I found mine on ifixit.com.

On a unibody MacBook pro you have only to remove the screws on the bottom (remembering the positions as few of them are different), and lift the bottom cover.

You will find a miniature flat cable on one of the corners of the motherboard. Just gently push it in the connector to make sure it is well attached. Important! make sure you have a static wrist strap connected to ground, or in alternative touch a ground connection before in order to get rid of any static you might have on your body.

Hope this helps
