Trying to restore a sony hifi mini set mhc-2600. Board from cd-player has some awfull trace damage from leaking capactor(s) (see picture).
Is this salvagable and what would be the best way to restore the traces except for jumper wires?...

FYI: The fsp-3528ic can be found on aliexpress no problems.

Thanks your reply!...

I would like to revive this thread as I'm trying to repair my FSP200-60ATV psu...
