When you press the power button you hear clicking but no picture
Presuming bulb was installed correctly it could be the ballast that powers it.
If possible try to look from outside where lamp is to see if it even fires up for a few seconds.

You have bad capacitors in the power supply that took out the regulator, or the ballast circuit is defective. Not really a repair for the novice. Good Luck

check for popped or raised tops on caps in power supply. also try unplugging set for 5 minutes and resetting it. How about does your color wheel spin up? if your color wheel don't startup then your tv will also shut down. also check all fans they all should be running at turn on. if all fails i would say its your light engine.

Listen closely. The tv should make a high pitch whine as it turns on. If it does wait and see if it tries this a few times. If yes then check the bulb, I have seen cases where the lamp shoves the power connector back into the set. If the tv starts with a grown or heavy vibration noise, then your color wheel may have broken and needs replaced.
