Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

I have a Vizio D55u-D1 no backlights Only power light comes on and fades away did flashlight test with nothing on screen seems like it’s shutting down can anyone help me narrow it down to what board needs...

If the power indicator "fades away", the power supply is a likely suspect.

Vizio TV that won't turn on gets 5v standby power but 19v for all the pins that are supposed to be 12v.

There may be faulty electrolytic capacitors on the power board check for them first by looking at the ends for bulging or leaking

I have a blank screen, with sound. From the right angle you can make out a faint picture. Tried messing with screen muting, auto lighting, etc. I replaced the main video board. Same problem remains.

Sounds like the backlight is not working. Check the LED backlight driver board.

Vizio d55u-d1 power light comes on then fades off. No sound or picture. Replaced power supply board, nothing still.

Chances are you have a main board issue, you should have run some voltage tests before replacing the power board, its sad how many people order boards that aren't bad because they don't do the necessary testing prior to ordering boards.
