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

For anyone else with this problem...I ended up getting a replacement transformer from ebay and swapping it out myself.
You have to remove the back panel of the TV, unplug the board from the harness going to it, unscrew the board (both via the set of screws going directly through the board and the set going through the plastic piece on the opposite side that, as far as I could tell, the board is glued to). This plastic piece (running the length of the board) has receptacles for the backlight bulbs, so be gentle getting it in and out. Don't forget the screw in the middle of the board.
De-soldering was a little tricky. My soldering skills are not great, so maybe it was me. But it certainly seemed to be a little challenging to get it all out. Having so many terminals probably didn't help (a capacitor would have been easier). Eventually though, I did get it out. Soldering in a new one was easy. Be sure to check continuity between the terminals of the new part and other parts of the board using the traces as a guide once you're done.
After that, simply re-install the board and put all hardware back in. Like I said before, be sure you re-engage the receptacles of all the backlight bulbs by pushing down at each notch on that plastic part of the board.
Hope this helps someone else...
