SOURCE: replacing ballast
To confirm if the ballast is bad check the ballast board to see if the spark gap (on the ballast board) lights when you first turn the set on. If it does than the ballast is ok.

I found R3 on the original board to be open, along with reading an open on CR1, D5 and D6. All the other transistors and the transformer check out. The only thing I have to do now is find out the specs of the diodes. The replacement board also had CR1, D5 and D6 open (R3 was OK). There had been some threads on various locations where remanufactured boards had bad components (the transistors were changed but not some of the other components).
