I have a computer that came in water damaged, powers on with no backlight. Corroded area was around C8560, rest of the board is clean. R8452 was missing w/ no pads & U8472 Hole in it. We jumped R8452 to R8453 & R8450. During the replacement of U8472, R8455 & R8481 may have been blown off. I could only find one resistor. Schematic does not say no stuff for either. Does anyone have a picture of that area of the board or does anyone know if both need to be on the board.
