Armstrong ultra SX 80 - 40403001

I have a board issue on:
FCC-1A
40403001
9738

I think a piece on the board shorted out. I another question answered back in 2010 that has a photo of the exact board that I have with the same piece that is burnt.

Can I just replace that piece or do I need to replace the whole board.

Thanks
