SOURCE: My samsung plasma suddenly made clicking noises and tuned off
I wish to tell the world about the simple cheap fix for your plasma! . Please let me know if I helped. I have a 50" Plasma that deicded after a year it didn't want to turn on anymore. It just blinked red LED. Which made me see red! It took me a year to find this inexpesive fix I hope this information will be helpful to you.... These are spendy items and none of us were thinking that after a year (seems like a scam to me) the TV just won't turn on anymore.... Then they say your no longer covered under warranty or you are and they send you to some repair shop 1-2 hours away and always and I mean always tells you the part is on back order.
Lukster is right it is a power supply problem. However you don't need a new board nor do you need to pay someone a ridiculouse abount of money to fix this. I fixed mine for 40 cents.
You more than likey have bad capacitors.
Unplug the TV from power. Remove the back cover. (some models require a star srewdriver) You power supply board is right in the center. A bad cap is bulgded or raised. A good one is flat. caps have an X on the top of them. More than likely you will see a bulding or just straight raised edges on the X on the top of the caps. Cap 3300uf 10v is the ones you are looking for. Once you find them replace them with 3300uf 16v caps. If one cap is not raised replace it anyway. These caps need to be a higher voltage that why the tend to pop. 16V is plenty, don't go any higher in voltage than that.
The caps need to be soldered on. You have 2 options do it yourself or unplug all the wire harness from the board then unscrew the board take your power board (dont forget your new caps) down to a pc repair or tv repair and have them solder them on for you. It will take less than 10 minutes. I do recommend putting the board in an anti static bag. You can buy these caps at radio shack or buy them on ebay.
After you get it repaired replace your board plug all power supply wire harness back onto the board (I recommend numbering the wires as you remove them), replace the back panel cover. Plug her in and fire her up. and BAM it works. then turn it on and off a few times in complete amazement at how simple and inexspensive this was to do. Then get angry cause your repeated calls to tech support was wasted breath.

I may have the fix.... Fixed two of my 50 inch plasmas that stopped turning on 1 year after I bought them. They both wouldn't turn on.... LOL Just gave me the black screen of death and a red blinking LED when I tried to turn on. I have pics and step by step instructions. Your time and under 40 bucks is what you'll need. I fixed both my sets for 80 cents. You can fix yours too.... I too got the it would be better to replace it than to have it fixed lie told to me too. I held out to the bitter end. Glad I did....

SOURCE: My phillips 50
sounds like its the CCFL trying to come back on, either that or like on my sony Bravia when it selects input sources it makes a clicking sound as well.
1) is got a bad CCFL
2) it has a bad psu
3) if its under warranty take it back

The clicking could be a loose connecction of the power plug or frrom the main power unit of your TV. Remove your plug and see the ends for burn outs, if so clean and use a different outlet. If not open the set after disconnection and check your main power supply unit for loose connection particularily in the surge protector, the main capacitor, the main drive, diodes or connectors. Wait to hear the sound and use a long insulated rod as a probe to confirm the origin of the sound. Solder or replace the damaged item. Hope this helps . Good day
