The top and bottom severly bowed, no convergence. Checking the
convergence power supply module, no voltage outputs. Changed the
STK730-130 with no help. Verified with a scope it was turned off. Not
oscillating.
A closer inspection of this module found an open R19722 :150K ohm
resistor in the feedback ckt. Replacement restored operation. Did a
touch up convergence and out the door.
And the customer said..
Oooooh yeah...
Cha-Ching!
