Your strobe is faulty and needs repair at a trained service center. The actual culprit may be the voltage converter circuit that supplies the high voltage to the flash capacitor, or the voltage divider that drives the ready lamp and, at the same time, makes triggering possible.

Hey there, I had one a couple of months back, but unfortunately I got rid of it since I no longer use it. But, you can certainly buy one online. Check out Amazon or Newegg. Good luck!
