You see that reddy-brown cylinder in the lower left corner just near the mains input? That's a fuse.

With the power disconnected, get your multimeter and measure the resistance of this.

Are you saying that you measure 310 volts across the 100uF capacitor?

If so, that's certainly in the range I would expect.

The next things I'd look at are the switching transistor and some of the components around it.

Please be careful as that 100uF capacitor will hold a charge for quite some time.

Do you hear any sound when you power it up (maybe a click?)
