If that fuse is on a 6.5V supply then it's not likely to be be relevant to the main bridge rectifier and smoothing electrolytic capacitor, both of which are possible suspects.
However, the damaged choke on the filter board, along with another one seem to have a rectangular block of metal inside them. Is this some kind of mechanical support? I'm still not entirely convinced there is nothing wrong with the board itself.
Also it's quite common to have a spike suppression varistor on input filters, and if they get more of a mains spike than they can handle, they can disintegrate quite dramatically. The usual 'remains' are a lot of flash residue and just a couple of wires sticking out of of the board seeming to go nowhere. is there anything like that there?
Finally, that flash damage is vaporised metal. It can be partly conductive so must be removed, otherwise it could cause another flashover.
