SOURCE: My Vizio VX32L LCD TV will power on but no picture or sound

I had the same problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound.

HOW I FIXED MINE: I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine. I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

For me the part number was either (depending on the vendor) : 0171 2272 2174 or it was 3632 0212 0150. Check your circuit and see if any of those numbers match up.

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.

My 70" Vizio smart TV will turn on but there is no picture or sound. I think it blew a fuse.. how do I fix it??


the first thing i would do id completely disconnect power to vizio tv and wait roughly two mins before plugging it back it. once that is done try to see if your picture comes back up . if your screen does not comes back the tv has unfortunately taken a turn for the worst. sometimes it costs more to repair than it does to replace so just make sure that your tv is or is not covered under a manufacturers warranty that may be able to have to tv replace for free depending on the scenario. below is the number and hours of operation. i also gave you a link to their support site. good luck!
