Vizio E320i-A2 Won't Power On

[thetugboat]

Evening. I am currently working on fixing a Vizio E320i-A2 Smart HDTV. It doesn't power on from the remote or the power button. I have tested the voltages coming from the boards. Power board seems to sending the correct voltages to the main board. Could you guys comment on the next steps to take or what may be the problem..thanks.

I'll attach a picture showing where voltages 'checked-out'. Give me one moment.

EDIT:
Looking at the main board, The uppermost connection is to the speakers; I assume there's no voltage there due to the TV not being "powered on" and no sound being sent to the speakers.(?)
The next connection is the LVDS cable. No voltages present at all there.
Then there's the cable running power from the power board to the main board. Voltages present.
Lastly at the bottom, there's the cable running to the sensor board and the power/menu button's board.

Could the issue be the main board?

How did you get the TV disassembled Tugboat? I have all the screws out, but the TV is structurally just as strong as it was with all the screws still installed. I'm at a loss here.

what about voltages at the transistors? on the other heat sink and those 3 opto couplers I have fixed some that have voltage present but not enough and voltage regulators on main board sometimes are faulty check those too
