Check D1SS16, a diode in secondary supply near the transformer. It's probably short circuit. Replace it with an SF-26, 400V, 2A rectifier diode, or equivalent.

You'll find some Samsung power supply boards here : http://www.usefulparts.com/index.php?main_page=index&manufacturers_id=11&sort=20a&filter_id=98&alpha_filter_id=0
but you have to open your TV first and find out model number

On all units that I repair, I replace all nine of the power supply board capacitors regardless of the voltages. There are poor quality capacitors and are going to fail at some time in the future.
The logic board caps are the same through hole type as the power supply. Yes there are many surface mount capacitors but none of these have need to be replaced. Replacing the logic board caps are very difficult because of the inner plane layer that acts like a giant heat sink. I use a desoldering station that has a suction pump and set the temperature to 850 degrees F. First I unsolder the square pad lead as this one is easy. The other lead requires more time, I hold the iron on until I can move the capacitor lead and turn on the suction as I pull the part out of the hole. Even with this process the holes do not always come clean and require additional work. Without the desoldering station it is very difficult and I would not recommend attempting it.
