First try plugging the tv into another wall outlet, see if the one its in now is off. Make sure the ac cord is well fitted into the tv and the wall outlet. If still no power (and no warranty left on the tv) remove the back cover and check the fuse if blown replace it. If the fuse is good then the power supply board needs to be tested. If you know someone who's technically savy let me know I'll walk them through some testing steps to find the problem. Get back too me..
This is the best I can do over the internet.......

Unfortunately, what you're describing is a repair issue. You won't be
able to address the problem with troubleshooting. There is a part
inside the TV that needs to be replaced. If you're under warranty,
this will cost you nothing. If you're not under warranty the cost
will likely be a minimum of $200 parts and labor. However, be warned
that the cost could be considerably higher. You should call the
manufacturer for your full range of options.

Your filter capacitors have popped due to diodes shorting, P-channel FETs shorting from gate-to-drain. Pull-up resistors have changed value and as a result your capacitors have peaked (popped)....so now the tv is in protection mode to prevent further damage to your tv. Take it to your local shop for servicing, or take it back if its under warranty......

Most probably the mainboard of the TV has a problem. But no worries as it is only 6 months old call up Vizio and they'll replace it for you free of charge :)
