Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

SOURCE: vizio 47" lcd no picture no sound has power

this could be one of two problem. first, check if you have back light. If you do then the problem is with the M/B. Second, if you don't have back light then the inverter is bad and needs to be replace.

SOURCE: Vizio 42" LCD HDTV audio issues

First of all go into the audio menu settings and turn off the "surround" feature off and that should fix the voices/music differences. Does the craking sound appear while watching any sorce such as cable box,sat rcvr or DVD player? If not isolate it to that input and maybe that device is giving the problem.

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: Vizio 42 in TV LCD HDTV white line across to of

That white line (usually jagged) is actuallly part of the transmitted picture. However, you are not intended to see it because it is located in what is known as the 5% overscan area. Your TVs today are more than just cable ready... they are a versital, technology filled multimedia display. You can see that line because the screen size or wide mode you are using is intended for 1080p/24 signals. You have 0% overscan with this screen size setting. This allows you to see ALL of the picture, including portions of the picture the broadcaster did not intend for you to see. You can change your screen size using the Wide feature in the Setup menu. See pg.62 of your user manual for details and descriptions of the various wide modes.

Why can't I get color on my Vizio M3D460SR

There could be a few potential causes for the issue with the color on your Vizio M3D460SR TV.
  • The first thing to check is the cable connections, ensure that all cables are securely connected and that there is no damage to the cables or the ports they are connected to.
  • It could be an issue with the TV's settings. Check the TV's color settings and ensure that they are set correctly.
  • The problem could be with the TV's T-con board, which is responsible for the image processing and color display. If the T-con board is malfunctioning, it may result in a lack of color or color distortion.
  • Another possibility is that the problem is with the TV's main board, which controls all the functions of the TV. If the main board is malfunctioning, it could result in a lack of color or other display issues.
It's hard to say without further troubleshooting, but it's likely that the problem is with the T-con board or the main board. If you're not comfortable troubleshooting, it's best to contact Vizio customer service for further assistance or contact a professional to take a look at it and provide a resolution.

lightning can do extensive damage to electronics equipment especially flat panel TV's. I would really recommend a professional diagnosis instead of board swapping. You could have several boards that are damaged!

Vizio HDTV E3DB420VX wont turn on

If your power indicator isn't lighting up, you don't have your 5vdc standby power. You're most likely looking at a power supply issue. Did this happen after a T-storm???

Describe your Vizio VX32LHDTV10A 32 in. HDTV LCD TV Problem. How to fix no power after a storm surged it to death...:((( Do you know where i can get detailed blueprints on the tv? My warranty ran out...

Searspartsdirect.com has blueprints


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.

Vizio vx42l hdtv back light

If backlight went out then sound should still work. Are there any indicator lights to show power is coming on anymore? Try unplugging for 30 seconds, hit power button a few times, then plug back in and try to turn on. This drains any capacitors of power to attempt to reset (basically clearing the TV's throat).

Can also try something on a different input. If current input is composite, S-video, or component, try using DVI or HDMI connection as this uses a different board in the TV. If that fixes it, then at least you can try to replace one board instead of entire tv. :)

Vizio L32 HDTV 10A won't turn on

I bought my 42" plasma Vizio 17 days ago and this problem just happened to me. We were watching and it just went off and it won't come back on. The tv clearly has power as the yellow light is on, but this tv simply won't come on. I called Walmart to verify I could return (I can) and they said they have two others that were returned sitting in back. I imagine this is going to force Vizio to do something soon, I can only imagine how many of these things are going to start failing in the years to come.
