Need help identifying display component logic board

Hi,

I bought my daughter a used MacBook Pro 13" mid 2012 a1287 i7 2.9ghz 750gb 8gb ram laptop for her 21st birthday, worked fine when I received it.

Anyway I stored it away ready for the big day. She opened it up, pressed the start button, we heard the chime but nothing appeared on screen. The ebay seller was unhelpful since 'it worked on arrival'

After trying every command prompt available from the internet to get it going we finally opened it up to eventually find a severely corroded possible resistor on the logic board which disintegrated to dust upon trying to give a very light clean. The missing / corroded to dust part is part of the display section of the logic board. The laptop itself runs fine, can even log in using the password I set up and the apple logo on the back of the lid lights up. Can play a DVD and hear it but nothing on screen.

A local repair guy has many generic resistors and capacitors that could possibly fix it if we can identify the part.

Does anyone know what part number or name the corroded missing part circled in the photo attached might be?

Thanks
