Описание к видео 55 inch Vizio smart TV, white light at bottom comes on but no picture. Backlights or Board?

Here we have a Vizio smart TV model E550i-B2 that powers on and gets the white standby light at the bottom left corner, but has just a black screen with no picture, but may still have sound.
We will troubleshoot this Vizio led TV to find out why it wont turn on. We will determine if its the Main board, separate LED driver board, or actual backlights.
