THE PROBLEM IS Faulty parts on PS board , bad press for Samsung
Because the Samsung LNS4051D would not turn on and the power LED would blink 4 times and the relay would click and this would repeat again and again. I replaced power supply board parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors, three had their tops bulged up slightly that I missed on initial visual inspection. After seeing the reports of problems with these caps on http://www.fixya.com/support/t1336881-will_not_turn_or_off , I replaced them with Radio Shack part 272-1032, 1000 uf, 35v. They are slightly bigger, but fit OK. TV is working fine now. Cost was 4 x $1.59 = $6.36 plus the time. I saved between $100 to 300 in the process of either replacing the board or getting the unit serviced.

I had a similar problem with my 32 inch plasma tv. I called vizio's
1 800 number and the guy said to unplug the tv from the wall and hold down the power button for a minute and then plug the tv back in outlet and turn on. And it works I guess from what I understood from his heavy accent was that the tv retains power and this resets it somehow. hope that was helpfull!!
