Do you mean the Vizio D32F-F1?

For any TV, first make sure that the current input is TV. For the D32F-F1, you can use the Input button on the back of the TV; it's the one at the bottom of the control buttons. There is also an Input button on the remote. Press the left/right arrow buttons or press the Input button repeatedly to navigate to the desired source. Press OK to change to this input.

Once the input is set to TV, press the Menu button. Navigate to the Channels menu item with the arrow keys and press OK. Highlight Find Channels and press OK. The manual for the Vizio D32-F1 is available on the product page: . The current link to the manual is .

I hope this helps.

you could do a force back light test .
Remove power cord, remove 1 side of the cable going between the main board and Power board. Plug in power cord and see if you get back light. The light should be on FULL since the main board is removed from the equation.

If backlight is fully bright then it could be the main board causing the problem. Any time you cant see main menu of the TV it also could be main board problem,

If you do force backlight test and the LED still do not look like htey are firing then it could be Power board or LEDs themselves.
Check voltage on CN802 and CNI801, proper low voltage should be listed there
Also CN201 pin 14 should be 1v-4v -> thats the diming signal
