Question about Samsung LE40R74BDX 40 in. LCD Television
It sounds like you have a bad slave inverter board. I've fixed a few of them with the same problem and it's always been this board. With the back off of the tv, it will be the board located all the way to the end where the problem is. It will have several wires going from it to the screen. You will probably have to get the part number off of the board to be able to find one, as I couldn't find one by using that model number.
