ok, yes i know im stupid, well my dad cause he did it . he left the brightness wire going into the pot on the white block unpluged when he powered it up....... It used to work except the focus would gradually fade spark back repeats... now this no hv i think it was touching resistor r 907.
 
Did you get any smoke? Ive seen this fry the 555, which in turn melts the little transformer in the cage..

Make sure you have the +- 34v going in.

Then check the signals on the 555 (pull the HOT so you dont get HV). You should get about a 20khz square wave coming off of the 555.
