??Have you checked the operating B+ voltage, and the HV ?? Check the inside
of the anode cup to see if there are any carbon tracks that have built up,
if so you may need to replace the actual suction cup assembly for another
fly, such as the original one. Is the number on the new flyback the same as
the original? Does the neck of the CRT glow a strange bluish colour when
the arcing occurs?

definatly coming from under the cap. Is it possible the HV is WAY to
high? if so and I manage to seal it, would this cause problems?

I am working on a Toshiba 32hf72 chassis N2PS. Found a bad flyback and
replaced it. Now there is a problem with the HV sparking. At first it
sparked around the anode connector. I cleaned that with no effect. I
have found a couple things that don't make sense to me:

Connected the HV to another tube and connecting the dag together with
no other connections yield proper start up with no sparking.
Connecting the tv together normally, but using a different yoke that is
not on the tube makes the tv start up, but it sound wrong. there is a
sound like sizzling inside the tube. Hard to describe. if the yoke on
the tube is connected instead of the other yoke, I get sparking again.
ANY ideas?

Power up the monitor while in the dark - you should then be able to
locate
where the arc is occurring from and work from there. If it's coming from
where the cap meets the tube, try using RTV to seal the connection.
