Be careful around the capacitor in that thing, the voltage could kill!
The capacitor looks like a battery (a cylinder) with the connections soldered to the circut board, it holds voltage to make electronics work better, but like a rechargable battery it holds an electrical charge until needed.
If you can get a pair of linesman's gloves, the kind they use to fix the high tension wires, wear them before trying to do anything with the capacitor.
Good luck and keep safe.
I should have chosen "Cut-n-Paste" as a forum name, since that is what I do, mostly.
