The power supply or the backlight inverter boards may have blown, you need to go inside.

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. :)
