The two most common faults causing the P/S to go into burst mode I've seen on the 224x supplies
have been one or more shorted rectifier diodes on the secondary or a bad HV multiplier.
Another not so obvious fault is that the 0.1 ohm current limiting resistor has increased slightly
in value causing the supply to shut down prematurely.
