Unplug power cord- safety first!
open backcover
check powersupply- top center right is p.s.
top left side of powersupply you'll see 5 capacitor 3300uF 10V.
see any pop up on top? replace it All with same rate or 16v is O.K.
do not use temperature rate 75c. Use 105C.
if you know how to solder. you save $300 least!

Without seeing the unit itself and opening it up/running tests I couldn't tell you exactly what is happening, however I can offer some suggestions as to what it could be.
1) your power supply is bad. That clicking sound is the power relay coming on and going off.
2) your main board is bad. It handles a lot of your signals for powering on your set. If it's bad, the tv won't turn on correctly as it doesn't recieve all the right signals.
3) your Y or Z boards are bad. These could cause the power supply to go into shutdown if the voltages on these things are too far out of whack.
Easiest way to tell if you're going to go into your tv is to try to unplug your Y and Z boards and turn it on. If it turns on and stays on chances are one of those two boards are bad.

This is a common problem.i recomend using your warranty if it still applies.if not, try hooking it up to a playstation and play with it.

Hello sir, hi, the symptom you have describe can be traced on the Power Supply board, either minor problem such as loose connections and screws, or a major one that needs replacement of the entire Power supply board.
You choose:
Have a look, and check for loose contacts, screws that needs to be tighten but you need to open up that big TV.
Or if that does not solve the problem, its the major one, needs to replace the entire PS board.
