Question about Vizio L30WGU 30 in. HD-Ready LCD Television
If you can provide pictures/description of what you did to get your tv working I would really appreciate it as my set went dark this morning. I'm thinking of buying a refurbished inverter board as a new one is $330 according to Vizio (part no. V08914430104) through www.vancebaldwin.com

Try unplugging the TV for a few minutes (discharges the ballast/ps) then plug in and attempt to power on. I have the 42P Vizio over two years old and ran into the same problem a few times. First thought was a power supply issue, but the unplugging trick worked. Good luck.

It's either the backlight lamp or backlight inverter is busted
due to a power failure or fluctuation. Here's how to determine which is which:

It may well be the power supply. Filter capacitors have a nasty tendency of blowing, as well as voltage control ICs. If the filter blows, you end up with a shaky DC signal that can't be effectively used by digital components (which make up about 80% of modern TV circuits). If you're within warranty/exchange then go for the manufacturer. If not, and you're comfortable with opening these things, then you can carefully (after unplugging and allowing it to discharge) take a glance inside. If any capacitor(s) are visibly blown out, then there's your problem.
