We found a vizio LCD tv outside so we brought it in in the hopes that we found a good tv for free. We didn't find a power cord but the one from our computer fits it. And the light on the front comes up orange. We don't get any sound or picture. Do we need to buy a real power cord for it? Or could it be something else inside the tv?

SOURCE: no picture or sound, light comes on in the front and have to unplug tv to turn it off.

I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.

SOURCE: I need help with disassembly of Vizio GV42L LCD TV

remove all the screws and start at the bottom and push in the tabs, and work around the edges, being careful not to pry too hard, the cover has clips all around the tv. after the bottom is free and one of the corners the cover will kind of pop off if you use the palm of your hand and lightly tap as you apply sum upward pressure.

SOURCE: The LCD screen is dark with no sound or picture when turned on.

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:Look through the back vents for a white light to make sure the backlight still works. 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.
