Does it do this using more than one input? Have you tried using a different source such as DVD? IF using HDMI inputs does it do it on all of them? I have seen this trouble because of configuration issues with some satellite boxes also have seen similar issues because of a bad HDMI input.

    Yes, it has the problem no matter the input. In fact the logo at start-up does the same thing so I know it is not the input source or cable. I also know it is the internal programable system because I can get rid of the worst of it by turning the backlight control to the lowest setting and then increasing the brightness to compensate. The downside it that now bright areas now have cyan lines. So it is trading dark+red for light+cyan artifacts. Thanks for your help

    I also did the Restore Factory Default reset menu item, but that did not change it. Any thoughts why this would happen?

    Hello, Rocky is wrong do not replace the back lite board, it's either the t-con or a bad display panel and my money is on the panel. the way to tell is you have to unplug the lvds cable from the t-con and see if the lines are still there, the screen should be a very bright blank screen.....tks

    Just in case anyone else has this problem, it is now gone! I temporarily got rid of it by using the custom display parameter screen to turn the backlight down to zero (still plenty bright) and turned brightness up to about 65. That made it watchable and after a few months, it just slowly disappeared and I can turn up the backlight if needed. It is known that some analog (like the DAC converters) do age (like a fine wine) and so probably some units were over driven at factory setup or did not get enough burn-in time before shipment.

Wavy red lines or red pixelation, not sure what it is


Go to Vizio website and buy the extending warranty, you need to have your TV replaced since the problem is with the screen itself.
