Question about Televison & Video
Some power? I would recommend you should get a sams photofact reference on your set and find out what voltages you should have at all exit points from the power supply.
I did find this entry on some people who had similar problems.
If you are handy with a soldering iron and not afraid to take apart the set give this a try!
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. If you are not comfortable replacing components which means using a soldering iron, you can replace the power circuit board, available from http://www.discount-************/ProductDetails.asp?ProductCode=1030952-SAMSUNG&&Click=46
