Question about Televison & Video
The click you hear is the power relay engaging. If you get no further indication of any cactivity or you jsut hear a second click, there is an internal problem and the protection circuits are shutting down the set. Was there any symptoms prior to the set being dead? If not, the most likely cause is either a shorted horizontal output transistor or convergence ICs (assuming a CRT based set). Usually DLP or LCD based projection sets have indicators on the front that will flash when there is a problem with the lamps. If you can post the make and model, I can provide a more detailed explanation and possible fixes.

It sounds like a faulty component on the power supply. Capacitors can cause that click you are describing so if you start your check there you might find the problem pretty quickly. Also check resistors near the faulty cap as these could have been taken out. If you are not able to check this yourself entrust a competant technician. Good luck.

Try doing this:
Self-check indication only:
Produce TV reception screen, and while pressing [VOLUME ( - )] button on the main unit, press [OK] button on the remote control
for more than 3 seconds.
Self-check indication and forced to factory shipment setting:
Produce TV reception screen, and while pressing [VOLUME ( - )] button on the main unit, press [MENU] button on the remote
control for more than 3 seconds.
Disconnect the AC cord from wall outlet.
This is straight out of the service manual.

This is an indication of leaky filter electrolytic capacitor on the power supply section.
A dried up main filter capacitor
or other filter capacitor in the power supply will produced an
out-of-regulation condition until it warms up.The symptom will get worst if not isolated.
I've advice you to look for a qualified technician to replaced the said parts.But first check if your unit is under warranty then avail it because the manufacturer of your unit will fix it for free or a little charge only.
Thanks for using fixya.
