OC is right.

If you have a pulse at the fly and no HV, the rectifier tube is the next suspect.

What I would do if I didn't have a HV probe handy is to hold an insulated screwdriver at my fingertips and touch the cap of the HV rectifier tube. In a dark room, you should see the soft blue arcing between the tip of the screwdriver and the cap. Make sure the tool keeps at least two inches of plastic between your fingers and the metal shaft. If that CCFL tube lights, you should get a soft arc from the cap of the HV rectifier tube to the screwdriver.

If you see the arc, move to the anode connection on the picture tube and see if you have it there. If not, the HV rectifier tube or doorknob cap might be bad.
