Ok, so this TV was free but we think it's salvageable.
When you plug it in it turns on with the usual click. Vizio lights up orange, then fades out. The screen is lit up but you cannot access menu, input, anything like that. Side buttons are non functional. The screen stays on the whole time until it either times out/sleep mode or you unplug it. Sub power board has been replaced as we thought it may be faulty.
The back light does not light up even after sub power board replacement.
I cannot seem to find a data sheet or repair manual for this model or by part numbers, even with strong Google-fu.
I tested the "little black things" that the name I can't think of right now, (square, black, 3 pins each) on the main board. They tested as follows with my voltmeter(which doesn't mean much to me without knowing the correct values) also uploaded a pic naming them with the values on it if that's easier to understand:
Far left - bottom mid top
2.07 3.32 5.19
Right 2.03 3.25 5.19
Top Left Mid Right
.54 1.79 3.31
Bottom .54 1.79 3.24
Middle (right of the 4 cluster)
Bottom: 1.25
Mid: 2.49
Top: 5.21
Far right
Bottom: 11.75
Mid: 0
Top: 4.97
I uploaded pictures of all the boards. None of the capacitors seem bulged at all, none have leaked. Any help is appreciated.
