Do you still have your old board,if you do put it back in and see if it does like the New Board.
In the mean time I need to do some checking on this model ,Samsung has some of these sets
that you have to replace 3 boards and On one model their is a 680uf 25v Capacitor that goes bad.
Have you looked all the boards over to make sure you have no swollen or vented on Top capacitors? Check your pico fuses also they will look like resistors but will be green or yellow.
1amp - 7amp pico fuses.The person who told you that the buffer boards where probably ok do they do TV Repair Daily? Or do Samsung warranty work? Ps it is possiable that you got a defective board just because they are new/rebuilt means nothing when it comes to repair, Ive had to ship a many of boards back due to being DOA dead on arrival? I paid $279.00 for a Deflection board that was No Good that really got me,Plus they losted my SSB board and that was another nightmare.

The capacitor is bulging or puffing up more than the other capacitors beside it?Yes,replace it with a new capacitor with the same micro ferit and 5 to 10 higher voltages for a better heat resistance later.This suspicious capacitor is on the power supply board.That the board,where the power a/c cord plug into it.Yes,90-95% that ur tv problems.
