Open it up and take a look at the filter capacitors. They look like little oil silos or whatever. If any of them have visible holes or seem to have a puddle of brown-ish or black residue around the bottom, then they're blown out and need to be replaced. If not, then you'll have to take them out and test them with an LCR bridge to tell if they've changed capacitance. If the capacitors are fine, then check the voltage control IC, which is normally both soldered and held in with a screw against a part of the frame or a transformer. Again, if there's a hole or any melting going on, then that's totally fried.
