In the old days ceiling fans were fairly simple to troubleshoot but the addition of electronics has made them complex and difficult for the dubious advantages of slightly improved efficiency and being able to use a remote control with an appliance that is probably also cheaper to produce.
The circuit will have to be checked as far as possible and the supply verified using a multimeter, though regardless of that it seems unlikely the system will be capable of resetting with the power switched off.
Start up capacitor is likely bad. That's the rectangle thing in the bonnet with two wires. If you replace it, replace the on/off switch at three same time.
Try a bit of chewing gum on each of the blades separately, it seems to be out of balance.By trying each individually and turning on each time you should find the imbalance.Cheers Michael....Australia
