So I finally had time to look into this, it didn't fix the problem.
Also I sadly made things worse when soldering the new caps in place.
i've managed to lift off a trace line from the board from too much solder heat, the line in question is the one that goes from the C449 cap to some resistors in a section called U108. I think I can fix it by using a loop technique to reattach some wire but i'm not sure what resistor that trace line goes to.
Of course I could take out the resistors in U108 but i'm trying to avoid that, any one know what one the C449 trace line goes to?
Its either - R186, RR183, R182, R181, R180, R179, R178.
