Verify if it only happens on the antenna/cable input and if it works fine with dvd or other input, then it is a signal issue with the cable or antenna u r using and repair that problem and not the tv

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.

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.

The color red is starting to flow throughout the picture.


I have fixed a lot of Vizio TVs. You are getting red pixelation. Some people have green pixelation, too. Usually change main board and main connector cord for fix. Check with vizio and see if it is still under warranty. Some parts have a lifetime warranty. If you call support and give them your model number they may be aware of the problem. It is not your inputs or wiring. It is the boards inside the TV. Let me know how it turns out. Good luck, John.

Pink Screen on Vizio 37 inch with HDMI Connection


Hi,
I work as a contract technician for Vizio, and I can tell you from experience that replacing motherboard is one of the only solutions to this problem. The other solution if under warranty is to replace it. If you experience red, blue, or green pixels where dark shades (like nose, eyes, clothes, etc), call Vizio and accept nothing less than a full replacement! I have had situations where I replaced motherboard and within 2-3 hours the pixels return. Hope this helps.
