Hi

IC6003 is usually the culprit you may need to check the ht rail with a meter to make sure theirs no short circuit on that rail 135volts
Can you use a meter?
Let me know anything else you may have done
Their isnt a single thing that you can say causes this its a process of elimination

Let me know
Anthony
