had a totally knackered Samsung power supply which had to be replaced when I fitted new psu had clicking coming from new psu which turned out to be a faulty relay on the new Samsung p.s.u replacing the relay on the new power supply board got the TV working 100%
This problems is the power supply board is causes and the problems.Try website like Ebay.com buy a whole refurbish power supply board for the replacement,will solved this problems.
I have a Samsung Plasma PN50A450 and one night the TV turned off and the result of trying to turn it back on was simply the set trying to turn on, making a click sound and nothing happened. I pulled the back off, and attempted the capacitor fix that is well documented on the Samsung LCD TVs. I did have a swelled capacitor that I replaced and also replaced the other capacitors that were the same Microfarad rating, temp and voltage which were replaced in a popular UTube video. That did not solve my problem, so I went onto Ebay and bought an entirely new power board for 69.00 plus 14.99 shipping. Replacing the board took about 3 minutes. TV is now working fine and will go back up on the wall in a day or 2. Note, the power board in my TV was a BN44-00205A. That board is no longer in stock anywhere ( I believe because it has been determined to be a bad board) I replaced it with BN44-00207A. Which I suspect is the board that is being used for replacements of the bad BN44-00205A. It fixed My TV. Hope this helps you. BTW, Both power boards are listed for replacing a board in the PN50A450, but the BN44-00207A Specifically states its for a PN50A450P1D. I took a gamble that the BN4400207A would work. It did.
You will need to have the power supply board replaced. This is a common problem and Samsung has re-designed the new boards so this will not happen again. You can call 1-800-samsung for the nearest authorizd service center.
there probably is ive had a similar problem i just opened mine up and replaced the power board fixed it but i dont at all recommend fixing your own tv take it to a pro :P
what the full model number of your tv? the clicking sound is the result of a faulty power supply, some capacitors(blown heads) on the power supply for the output voltage rail of the mains board need to be replaced.
There are several capacitors that are known, in Samsung TV's that go out.. ( I replaced mine until the board was burnt through.. bought a new board, they went out again.. BOUGHT A LG TV!!) Samsung settlement warrants older TVs with faulty capacitors
