Check the flat connection wire [LDVS] cable that connects the T'Con board and LCD panel for any loose contact. Re-set it once and check. If it do not help yoy, the T'Con board should be replaced It is faulty. If you wish to get more details, check this site linked below. Pull up older posts there.

SOURCE: my vizio sv470m screen keeps distorting the images

Could be power board, could be main board, could be LCD controller and lastly - very unlikely yet possible - could be cables or rather cable connections.

It would help a lot if you post a screenshot or, better yet, a video of the distortion.

I somehow do not relate "distortion" and "blacking out".
Yet if I had to make a pick based on what you say and my experience I'd look at the main board first.

You should be able to get a replacement for under $100 at eBay and if you know what a screwdriver is you should be able to replace it yourself - a slow, but certainly not difficult process even if you do it for the first time.

Still I don't recommend spedning money before sharing more details and getting a more informed guidance as to where to look.

Tint: 2
Sharpness: 3

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

Color Temperature: Normal

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

Blank on ALL video modes?
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

HDMI makes black screen


IT sounds like the ccfl tubes (the bulbs that help light your tv) are going out. Think about replacing them. You'd need to take it in to get this done. Also, it may be cheaper just to replace the TV entirely, given the cost of replacing the tubes.
Good Luck!

Try unplugging all units involved for a while--make the HDMI connection when they are disconnected from power--HDMI does not like being hooked up to units that are powered and or on.

Vizio SV470M Issue Sound No Picture


Do you have backlight? If you do, you have a bad main logic board. Very common with vizio and are hard to find. They are usually out of stock everywhere.

How do i set the color on my vizio sv470m. it has


Your main problem is that you bought a cheap Vizio tele instead of a Samsung or Sony.  Theres a reason why these teles are cheaper.  They have barely any quality control.  Don't buy a tele cause a football player says its all good.  Try going into the settings and adjust the contrast and hue or take the thing back to the shop for refund if you feel this unit is just rubbish.
Cheers.

Horizontal line at top of screen in any hd format with componet or hdmi. model is sv470m. the tv isn't even a week old.


Get into the TV menu and locate the H (Horizontal) and V (Vertical) picture options. . .increase the V until line at the top is gone.
