Need help identifying a component on logic board
i have a client who spilled a smoothie on her MacBook Pro a1278.
When powered up, the chime sounds and the HD spins, but there is no response from the LCD display.
I noticed that there was a corroded chip on the logic board near the display cable, and was wondering if anyone could help me identify it, so i could figure out if it's the lcd or the logic board that needs repair (i don't have an extra lcd to test if it's the lcd).
Here's a photo with a red arrow pointing to the component.
thanks for any help!
