Its the main board 90% of the time when a vizio has that symptom.

SOURCE: Power is there, but TV won't turn on

stored voltages are high no touching these circuts becuase they hold charges and alot of screws.
fualty capacitors you say after a while it stays on theres a full charge in the unit theres some type of discharging effect on the set after its off for a while. voltage goes to low or unstable after it is off for a while. your better off getting the service docs for this set if you want to diy..other wise get a tv tech to check it for you. hope this helps

Vizio tv sv420m need help


Sure that the other boards you used were any good? If so, then try the Power supply board since the other boards of your set other than the main board specialize in the video aspects. Since you have no audio the only two boards that could account for no audio are the main board and the PS board which powers everything in the set.

VT420M no sound or picture and turns off by itself


this sounds like a main board failure but a defective power supply can mimic some symptoms of a bad main board. I would recommend you get a diagnosis done on the set. If I was a betting man, I'd guess the main board

I have a vizio tv and it wont turn on it showed the vizio logo and now it wont turn on and its been like this for 2 days


The main board will need replacement. Its very common issue where the set will freeze at the vizio kogo then eventually it wont turn the logo from orange to white so it can power up. Replacing the main board should solve the issue. You can get the replacement main board from www.tvcircuitboards.com

Solutions (2) Best Solution That little fella is only turned off by unplugging it. If all those little lights in America could be turned off we could do with one less nuclear power plant. If unplugging it is not an option, my wife's solution is to cover it with a piece of black tape.

remove all screws on the back of the tv, carefully pull off back cover. you will see two circuit boards one on the left (Power) and one on the right (Video) on the Video board there is a small plug on the right side with a yellow, white and red wire going into a small white connector. the red wire is what controls the orange light on the front. now that the plug is pulled turn it over and you should see a small white plastic piece that holds each metal connector on the end of the wires in. pry this piece of plastic up for the red wire and pull at the same time, the wire will come out of the connector. now tape the metal connector with electrical tape and tuck it behind something or tape it to the chassis. plug your connector back in. put the rear cover back on. now your tv will only show the vizio logo in white when you have the power on. If you wish to disable the logo for both orange and white just disconnect the white plug completely.

VIZIO TV Black screen. Cannot turn off TV without unplugging.


I had a similar 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. I didnt hear an arcing sound though. 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. I would check the ceramic fuse first on the board that gets power from the plug.

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.
