Be very careful replacing it, those things have usually 450 volts and that can KILL a bear.

Oops- I just started putting back together the Samsung I was working on- model LN-T2353H A, and I forgot to mark where one of the connectors goes. And there are two sockets for this one and it fits in both! I'm usually a much better technician than this but I thought I'd remember which one it goes in. Pics attached- if anybody can let me know which one the connector should fit into I'd much appreciate it.

most of the pins (24v & gnd) are the same except for the backlight control pins 11~14. check on the back of the inverter board to see the pin labels. I would think if placed on the wrong plug, the backlight would not come on but I doubt there would be any damage as those are only control lines.
I suspect it should connect to CN803 (plug nearest to the edge of the board)

Just look at the pin out of the Inverter board connector to locate the BL_ON pin then match it up with the connector of the power supply board.
You can see that the two connectors of the power supply board does not have BL-ON pin at the same location and also as shown on the schematic.
