i have a vizio VO42L FHDTV10A.
the screen is black, the tv powers up.
vizio sign is orange when plugged in turns white when i hit the power button, turns off when i hit the power button.
i replaced the power supply board and the main board with all the inputs on it.
still have no picture.....does this mean the backlight is burnt out?
can i replace the back light?
i have a working back light if so but dont know if this is going to work and never done this before.
dont want to waste my time if this isnt a possible fix.
the backlight i have is from the same exact model but the plastic screen is cracked....the backlight fully lights up on the broken screen one.
i was hoping i can just switch out the backlight.
can anyone help??

TV off, hold down on the input button and the tv will turn on by itself.

Maybe it's time to look into the inverter? Since you've replaced everything else. Most backlights are supposed to last some 60k hours. CCFL lamps. Sort of like what's in a laptop screen.
