Screen goes pink, when I press bottom of the case it works

My user has a MAC book Pro 15" mid 2010 model and recently the screen started going pink. I believe he dropped the machine. When you press the bottom of the case, the screen goes normal. When I opened the back I noticed a little plastic clip is broken directly next to where the battery connects to the logic board. It’s the plastic "clip" under the metal VGA Ribbon cable protector. When you press there with your finger, the display is working correctly, so it looks like because the clip is broken, there is a loose connection. I am not sure how it’s affecting it though - it must be putting pressure on it or something.

Can you guys get those plastic clips?
