Vizio e3d320vx need help please

[Greywolf74]

I have a Vizio e3d320vx 32 inch LCD TV. When I press the power button the power light comes on, the screen initially lights up and displays the vizio logo for a couple seconds and then it goes black. It then momentarily lights up (but still no picture) and then goes dark again. If I shine a flash light along the edge of the screen I can see that there is a picture and I do have sound. Im assuming the PSU/inverter needs replaced but Im not sure if it could possibly be something else instead.

Thoughts?

Could be PSU or inverter, or maybe even CCFL lamps

post #5, first picture, bottom right. There is a connector, measure all pins the DC voltages and post them back with the corresponding pin out name.
