I cant understand so many replies missing something obvious!

lets take it in steps.

open the unit and clean it completely, the cage, the focus block, the
transformer and ht leads.

then run the pyro-display again for a few seconds!!!!

next examin the cage and ht components for burn marks.

it could be the transformer, but i doubt it!

if you get no ht at the tube, but a good arc then it's getting voltage from
somewhere!!!

i would start by suspecting damaged cables or a faulty 'focus block'.

(focus blocks are easy to get from tv spares companys)

if it is the transformer, then you may get lucky, i have just got a ht-box with
no transformer in it, i am going to try to adapt it for a different tranny!

like others have said, when you do get arcing transformers they cant hide there
guilt!
look for anything from a crack like an axe wound :-)
to a small mark like a cigarette burn.

it will be near a small black/blue mark on the metalwork.

P.s. POST SOME PICTURES OF THE PLASMA-BOX!!!
