The clicking usually means that the switching power supply is trying to
start, it then detects an over-current situation (short), shuts down,
then trys all over again.
Have you checked the Horizontal Output Transistor (HOT) for shorts ?
You can check this using the diode-check on your meter.
Are you getting any secondary voltages from the power supply ?
Any voltage on the collector of the HOT ?

Hi John,
Thanks for the reply.
Okay I have checked the HOT in-circuit with my ohm meter. I'm reading
shorted. The part number is (C5521.96). There is a flat pack diode on
the same heat sink with the cathode going to the collector of the HOT
it reads short as well. Part number 1G123S15
