Question Samsung LCD TV problem

I have Samsung LCD TV 32 inch Model No LA32E420E2RMXL. It suddenly died yesterday. As you can see in the pictures, the backlight inverter use SEM2106 IC and i cant find the datasheet for it. The inverter balancer board is confusing for me. In every CFL connection ive seen, theres always two wires. But theres only single contact each in six position in a slot contact type connector as you can see from the picture. In the last picture, i have drawn red rectangle to show that these two mosfet were burnt, and i cant see the markings. Also it seems to switch the high voltage instead of low voltage (12-15v) in most inverter circuit. Can anybody help me with this TV please?
