She's done. You can try it you want, but I would bet that is already burned open circuit.
You also do not need to separate the boards. Especially since the cap already blew. You remove that rubber plug- it will pull off over the leads. Then use a soldering iron to heat the lead one at a time and pull them out. Leave your new capacitor with longer leads to leave a gap between the cap and the board, and use a fine tip soldering iron and you can solder a new cap back in place.
But honestly, again, ROI on that amount of work and effort, the board likely is dead.
