Panasonic rear projection TV 47 in PT 47WX49
i have the same model and this happened to my set 1 day after yours! i am sending it out for repair on monday so i can let u know what was done and what it cost. i found this:
from repairfaq.org: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.
