Tv completeley went out , first the picture then sound. took it to a tv repair shop and the power board checks out ok can not find the problem so he is not chargeing me wants me to pick it up

On the Vizio LCD TVs there are only two boards: Main board and power board.
There is also the screen. If they checked the power board then all that is left is the main board or screen. If the power light stills changes color when ther power button is pressed you may have a bad screen (costs more than the TV if even available)
If no lights come on the main board can be tried to see if it fixes it, the main board will cost $200-$400.
These screens go bad so I'll bet the shop did not want to try the main board as they can not return it after buying it
Buy a new set is my advice
Hope this helps

Why my tv power keep blinkin on and off VIZIO XVT3D424SV 42-Inch Full HD 3D

Because there is a failure in some module which the power or main board detects and refuses to power on.

The blink is a series of short blinks which report the error code - count them, report it and you may learn more.

It is worth saying that most of the times error codes do not help too much.

Having the TV , testing the power outputs and experimenting with disconnecting boards usually helps better.

Of course there are exceptions to both rules.

Your power board has gone out. If your tv is under warrenty then you can get it done for no cost. Vizio will send power board and main board and Tv tech will come on-site to install the parts.

I have a 42 inch vizio plasma t.v. and I have power but no sound or picture, I've unplugged it all night and still doesn't work! It's

For the 42" plasma, you need to change your sustainer boards or your main board to fix the problem. If your TV is still under warranty, call 877-MY-VIZIO and they will have a technician go to your home and fix the problem for free.

For the L42 HDTV, you need to change the inverter boards or the main board. If your TV is still under warranty, call 877-MY-VIZIO and they will have a technician go to your home and fix the problem for free.
