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.

SOURCE: I think I need a new power module for my Vizio

Remove the 4 screws holding the stand. Remove all the perimeter screws. Remove all the screws from the bottom speaker panel and the rest of the perimeter screws and the ground wire screws at each speaker. remove the screws on the surface of the back panel and you are in. The power supply is the large board in the middle. The bad capacitors are in the secondary and were C233, C234, and C236. I replaced these 3 capacitors and fixed this problem. They were 1-10v 1000uF and 2- 10v 3300uF electrolitic board mount capacitors. Easy to spot on the power board, the tops were bulged up. $5.54 later it works perfectly now.

My vizio VW42L has a picture, but the sound went out....how can we get the sound back


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.

Vizio VW42L HDTV10A, Black screen name display on no sound nothing,VIZIO tech says suapects backlight bulbs, but why wouldn


If the backlights lamps are bad, you will not get picture but will still have sound. Lamps (est. life of 50k hours) are rarely goes out, its electronics that go out first. I do not think the person you talk too ever work on the LCD TV.
More liekly that the 12v (for sound) and the 24vdc (for backlights) power supply section is not working.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

42" vizio vw42l - no picture or sound


If the backlights for the screen do come on and you also have 12v and 5v feed the main board then it does sound like the mainboard will need to be replaced.

Vizio GV42L 42inch LCD/HDTV


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 kmarlin@grandvalleygolfclub.com. thanks, keith

Vizio VW32L HDTV10A stopped responding with Vizio


Change the batteries in your remote. If your cat was laying on a button it could have drained them.

Here's tip - you can use your camera on your cell phone to see the IR signal coming out of your remote. Point the remote at your cam and press "On" or any button. You should see a bright flash with every key stroke.
