Nothing works, so the common factor is the power supply and although the switching power supplies look different then the old ones, I think you can find the power supply and see if all voltages are still available. When you have opened it, check for bad connections and for bursted electrolytic capacitors.
Good luck.

TV made a steady high pitched noise and went black. Vizio logo still lights but no sound or picture.VX 32L HDTV10A.

Unplug it and do not try to use it to limit the damage. You need to look at the power supply module to see if it has any sign of bad DC filter caps with leaking/bulging tops.

Vizio vx42L no power will not come on just went

First place to check will be the power supply, look for blown fuse, burnt parts, bad caps with bulging tops. Check for DC voltages, you should have 5, 12, and 24vdc at the power supply DC output connectors.
Parts: check

Vizio vx42l hdtv back light

If backlight went out then sound should still work. Are there any indicator lights to show power is coming on anymore? Try unplugging for 30 seconds, hit power button a few times, then plug back in and try to turn on. This drains any capacitors of power to attempt to reset (basically clearing the TV's throat).

Can also try something on a different input. If current input is composite, S-video, or component, try using DVI or HDMI connection as this uses a different board in the TV. If that fixes it, then at least you can try to replace one board instead of entire tv. :)
