SOURCE: vizio plasma tv turned off..won;t turn back on

This sounds like the main power board went bad. If this is still under warranty, contact 1-877-MYVIZIO and they will have it repaired for you. if not, let me know and I will guide you to the right part.

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: It won't turn on

I replaced 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.

SOURCE: Vizio VW32LF powers up no sound no picture unplug to turn off

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.

I have a Vizio E472VL television. When I go to turn it on the logo appears on the screen and the "vizio" icon back light turns on, but nothing else happens. I have tried coax, component, HDMI, etc..


Had the same thing happen to my Vizio TV. It was on warranty, and they replaced the motherboard. It's been fine since then. There appear to be only a very few parts inside. Power supply, motherboard, and display. That's it. Your power supply is good, as is your display. You just need a motherboard.

My TV cut off by itself.


I'm not a repairman, but I do know that a lot of sudden power-offs happen due to overheating. If an electronic device gets too hot, it has a auto shut off function that kicks in. Try unplugging it for 10-30 minutes and then try it. If its plugged into a surge protector, try plugging it directly into the wall outlet.

Vizio remote won't control tv


I just had the same problem. I call Vizio and this is what they had me do that did fix the problem.
1. Unplug the TV
2. Hold down the power button on the TV for 30 seconds (yes, with it unplugged and do not plug it back in yet.)
3. Take the batteries out of the remote.
4. Press each button remote twice to ensure that they bounce back and are not stuck.
5. Place new batteries into the remote.
6. Plug the TV back in. Not into a power strip if possible. ( I did not have an available outlet so I used a power strip.)
7. Try turning the TV on using the remote. (My TV turned on. All of the functions worked - problem fixed.)
Hope that this helps.

My DCT6200 cable box keeps shutting itself off and then turning back on. I have already tried resetting it by unplugging, but that has done nothing. Even after I have turned off the power and left it...


1) have you tried changing that box in that room to another and the box from the other to this room. That may give you an idea of either power or signal strength issue.
2) after it resets does a "dl" show up on the box front. if so it is trying to download a firmware/software update and everythime you power cycle it starts over.
3) turn the box off then hit select and go to option 8. there should be 4 modules enabled.
4) you may need a new box

Vizio LCD 37 Inch Turns Off Randomly


I had a similar problem with my 32 inch plasma tv. I called vizio's
1 800 number and the guy said to unplug the tv from the wall and hold down the power button for a minute and then plug the tv back in outlet and turn on. And it works I guess from what I understood from his heavy accent was that the tv retains power and this resets it somehow. hope that was helpfull!!
