You need to leave a lot more information than that.What is the background of replacing the lamp? Where is the clicking noise coming from? Is the lamp light flashing, etc.? My current best guess is that your ballast may be bad, but more info is always helpful in diagnosing a problem. Good luck.

Why does my Panasonic 52 inch rear projection TV make a clicking noise with no picture after turning on the power? I replaced the lamp a year ago with no issues.

You might want to look at the lamp again to see it is intact and not shattered----2,000 hours or 2 years is normal life for a OEM lamp but a generic or cheaper version lasts about a year and picture is usually not as bright as with the original ones.

Just repalced the lamp on still have the red light for lamp on

Make sure the door of the lamp is closed.
If the lamp is good, you may have a bad ballast or a ballast voltage is missing.

Replaced lamp in my HD 61Z575, but when I turn on my TV, nothing happens (no fan noise). After ~10 seconds, the Light LED starts blinking rapidly. Could it possibly be the brand new lamp? Ballast?

The old lamp was in there before the fan work?U replaced the lamp u put the door back on did u make sure the safety latch is off and tightly closed with the the lamp door.The continue blinking LED light does it make alot of clicking noises too.Yes,then the Ballast board it is dead too.The Ballast board only job are to help the projection lamp to ignite to work.

Won't power on

Have you checked the power cable or the back cover of your television? Often times, customers forget to plug their television in after a repair. The back cover for most DLP or LCD projection televisions have a sensor as well that will keep the television from turning on. If there is still no power after the steps below, you may have a problem with your power supply module.Consult your owner's manual or a service technician for assistance..
If the previous advice wasn't helpful, try this: Do you hear your ballast "click?" The ballast is what powers the lamp. Initially, UHP lamps need to be jump-started with a lot of energy. The ballast will make a clicking noise as it starts up the lamp. If there is no clicking noise, there may be no power to the ballast or the lamp.

Bad power supply. Symptoms: No display at all, no power indicator light, no sound from speakers, momentary popping or clicking noise, "burnt electronics" smell. Typically caused by failed capacitors. Can be usually be repalced and continue to have working display for a long time. Repair: Replace power supply. Super cheap when it's just a couple of bad capacitor to medium expense when repalcing whole power supply unit.

Keeps switching itsself off

Check the lamp first. Observe the light where the lamp door is on the back of the set. If the light is going out, its likely the lamp, especially if its 2 or more years old. If the lamp has been recently repalced, make sure the lamp door is properly aligned so the interlock switch is engaged.
