What whas the problem, if there any solution. I dont even have 8 mo. with it.

Thank you.

one quick fix you can try. plug in the HDMI cable, slect a digital audio sound output from the sound settings on your machine, then leave it connected and restart it. It just might work.

SOURCE: 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 (you can also use 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.

How do I use a USB to watch a movie on Toshiba TV? Or hook computer up to TV to watch it?

Most recent laptops come with a port to connect to a TV, depending upon the input ports the TV has. The two most common are VGA and HDMI, and you will need to check which of these each item has. It is then simply a case of getting the appropriate cable to connect the two together, and then on the TV select the input from the menu, and on the laptop, make sure that the external video port is active (usually a Fnct and "F" key - eg Fnct + F5 for a Toshiba Satellite Pro U200).
Hope this is helpful, if so would you please register that with Fixya

How do i play movies from a tablet i plugged a hdmi cord but no response

You mentioned a "usb cable" but you cannot connect an external display to a tablet's USB ports. If you are using an HDMI cable, then you will need to select which display is active through the tablet's settings (Android) or control panel (Windows) and also make sure that the TV is set to the appropriate HDMI connection through the input selection.

Hi I have acer laptop, I have a cable one end is hdmi and the other side rgb, is there a down load driver so it will work. thank you

If you're trying to display output from the laptop to the Vizio you'd be better off using an HDMI to HDMI cable. The VGA port on the Vizio E320 only supports 640x480 resolution; you have to set your display output accordingly, usually in control panel. Using HDMI you're able to keep the signal HD, @720p. The E320 also supports 1080i, but you're not going to see all 1080 lines. If for some reason you're trying to go from the Vizio to the laptop it just doesn't work that way.

Trying to connect hdmi cable to laptop to watch movies

Are you sure you have four hdmi ports? I have only one hdmi port and three usb ports. Be sure you are connected to the hdmi port and for some reason not a usb port.

Problem with Vizio SV421XVT

I am also having the same symptoms for my SV421XVT. TV works great except all HDMI ports are not receiving signal. Devices work through the AV Ports, and TV reception is fine. New Roku box is also not working through HDMI but works with AV. Wish I had a solution to this.

On a another forum for another TV it was suggested that boards need to be replaced. I hope I can get these boards for a reasonable cost.

Connecting a new vizio bluew ray player. No signal being received on tv when connecting into usb port

You should never connect a Blue Ray or DVD player to a TV through a USB port. Use a scart/composite/component/HDMI connection to connect the player to the TV.

HDMI would be the best connection possible, but most devices don't come with a HDMI cable. Go to any electronics store and pick up a HDMI cable for about 10 dollars/euros. Don't pay for overly expensive (I'm looking at you, Monster Cables) as they are a giant waste of money.

I try to connect my hdmi cable to my laptop with a vizio hdmi cable and the tv says not format... how do i address this issue

The input which you are using sounds like a USB port (which is looking for a virtual drive that needs to be formatted). Double check to make sure your laptop actually has an HDMI input (most laptops do NOT). The USB ports are different than HDMI.
