Use your remote and find RESET from the settings. I have a tendency to reset the sound on my TV's with all of my remotes, sometimes a different remote for a different TV or stereo will do something funky and turn off my sound the only way to get it back is to reset the settings and reprogram the channels.

try main board as it controls all picture funtion. does the screen still light up? no picture...ect..

call the suggested retailer..

if there is entirely no backlight then yes, however if you just dont have a picture and just a blue screen then it is not the backlight it is the inverters, replace both is recommended.

Tell Vizio send out the tech.to replace ur Backlight video inverter board,it dying go to be dead sooner or later.Or take the refurbished tv ur tv will have dead video soon.

Does LCD screen backlight come on? If so proceed....
USE:CAUTION WHEN DOING THIS....
Try this if repairing yourself...find power supply, small board with no cover over it...check voltages on output pins/plug/connectors (white plugs) three in a row...
1 Plug has 24Volt supply..1 has 12Volt supply and 1 has 5Volt supply when read to ground (screw that holds board in) if you have these voltages it's a safe bet it's the main control board...I just replaced mine and it fixed a problem like yours.

there are several possibilities. first if the unit comes on and the "VIZIO" light turns white, but no picture or sound, then the main control board is most likely the issue. could be the LCD control board(s) depending on model one or two. and ultimately could be the power supply on the upper side....if the "VIZIO" light does NOT turn white, the whole power supply unit is out. after that, would have to scope the circuits to find out. Seems that the control board is the most common and tends to happen on many different sizes. new board will be around $350.00. Might get lucky and find a used one, but it MUST be EXACT part or it wont work right. if you dont find one or want to sell yours for parts, id be interested in the screen. can reach me at [email protected]. thanks, keith
