Th clicking is from the power relay. You will have to open it up, the first place to look will be the power supply module, look to see if it has any bad caps with leaking/bulging tops first, caps can look OK but can be bad due to high ESR.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Why won't the Samsung Authorised Dealer repair the board? It's not that difficult!
There will be a power fault and the picture is not "building" properly. At worst it will be one of the memory chips.
With a reflo soldering machine, no problem.

My samsung tv turns on and off repeatedly at


Mine was doing that then it quit even turning on so I replaced the 4 Capacitors today on the power supply board that had bulged up on the top 3 had split open they where on the top right corner of the board where the ribbon jumps from the power board to the main board with ones from Jameco Part Number 606521 they worked perfect but make sure you put them in with the correct polarity easy to do just keep an eye on it. Very simple repair and took me about 30 min to take itapart solder on the new ones and put it back together all for under $10.
