i found this on another forum, this is getting a little out of my understanding.

====================================================>

22.10) Power-on tick-tick-tick or click-click-click but no other action

A variety of power supply or startup problems can result in this or

similar behavior. Possibilities include:

* Lack of startup horizontal drive - see the section: "Startup problems - nothing happens, click, or tick-tick-tick sound". The main regulator is

cycling on overvoltage due to lack of load.

* Excessive load or faulty power supply cycling on its overcurrent

protection circuit.

* High voltage shutdown, or some other system detecting an out of regulation

condition. However, in this case, there should be some indication that the

deflection and HV is attempting to come up - momentary whine, static on the

screen, etc.

* A dried up main filter capacitor or other filter capacitor in the low

voltage power supply that is producing an out-of-regulation condition

until it warms up. A bad filter capacitor on the output of a series

regulator may result in excessive voltage and subsequent shutdown.

* A problem with the microcontroller, relay or its driver, or standby

power supply.

One possible test would be to vary the line voltage and observe the

set's behavior. It may work fine at one extreme (usually low) or the

other. This might give clues as to what is wrong.
