Polyester Capacitor Boom

This mess used to be part of a backlight inverter in some sort of wall-mounted media controller. As for the damage, both sides of the board are burned up, the capacitor itself is just gone, the wall had minor burns, and finally, the plastic case suffered some melt damage.

Now for the real surprise: the controller, which was thought to be well over ten years old, still actually worked, and yes, even the screen, although as expected, minus the backlight.
