If sound is there, only picture is absent, its back-light inverter board is faulty. If there is no sound & picture, its main board is faulty.

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 remote control not working

Hi, I had the same problem. My vizio remote for my 42 inch 2 month old vizio also seemed to stop working. Here's what I did: My vizio remote (like most remote's nowadays) was designed for multiple components (tv, dvd, vcr, etc). All you need to do to make the remote work again is set it back to tv. Now, the confusing thing about vizio remotes is that they actually have TWO places where you can switch the remote to the appliance you want to control. One is on top of the remote, the other is on the BOTTOM. Switch it back to TV using the BOTTOM. My remote had stopped working because I had inadvently switched it to another component on the BOTTOM component switch.

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 SV470M, picture is moving too fast

This is often called the "Soap Opera" effect...I had a similar problem and found that changing the settings helped tremendously. Here are the settings I use:
Picture Mode: Movie

Backlight: 18
Brightness: 49
Contrast: 52
Color: 42
Tint: 2
Sharpness: 3

Advanced Video
Noise Reduction: strong
Color enhancement: off
Advanced Adaptive Luma: Off
Enhanced Contrast Rato: off

Color Temperature: Normal
Red: 121
Green: 128
Blue: 118

Smooth Motion Effect: low
Real Cinema Mode: Precision

Also, there's a great thread on the Soap Opera effect here:

SOURCE: vizio 47" lcd, no picture,

Hi goldenstripm,
Power on the unit in the dark room then shine with the flashlight directly in the screen, you will barely see the images. This is because your backlight is not functioning. The following reason is the caused.
1. Power supply - missing B+(supply voltage) coming from this board feeding the inverter board. This is caused by faulty transistor, dried/leaky electrolytic capacitor, open fusible resistor.
2. Inverter board - even the B+ is good from the power supply, if the fuse, driver transistor, driver transformer is faulty no output to the backlight resulting to black picture.
3. Busted backlight - even inverter board is good but if this is busted resulting to black picture also.
Diagnosing the fault is technical and if you don't have necessary tools and test instrument and can't fix it yourself, I would advice you to look for an experienced technician to isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
