Question about Vizio VF Televison & Video

1 Answer

Vizio 55" Inconsistant Dark Screen

This problem has been on going for a few months now. The screen will have shaded/darkened portions. The most common case is 3/4 of the lower screen is dark. Its not black as you can still see the tv picture its just hard to see. Other times there will be flashing irregular shapes on the TV that are shaded. Other times there are just randomly shaded rectangles on the screen. I called Vizio they said backlight flooding. Is there something I can do to fix this?

You have to open the back cover to check weather the screen back light need replacement. usually if the lamp is almost black in color it needs replacement. the backlight is covered with metal shield installed at the upper portion and lower portion of the panel of the tv.

SOURCE: Vizio LCD Green Pixels

Our Vizio started doing the same thing after only three weeks, except it was also showing green pixel when we watched DVDs.  After checking this site and others and trying all the "tweaking" advised, I finally called Vizio's customer support.  They were extremely polite and tried to help over the phone, but had to send someone to the house to make the repair (anything 40 inches or larger earns a house call). The tech arrived on time and was extremely professional and pleasant -- he had to replace the daughter board and LVDS cables.  So far, so good.

Vizio 55 inch TV "Vizio E550I-B2" is Darker on the left viewing side, replaced the Power Supply board. And the Screen is still dark on the left side. Any suggestions?


It is a common problem for this TV, it uses a Sharp LED display panel. The problem is the data buffer IC inside the panel ether shorted, or burned open.
Vizio offers a extended exchange warranty if you have the original sale slip.

For more information, you may contact Vizio directly.

Why does the picture on my Vizio tv (model E241-A1) gets bright then darkens?


Check to see if you have a daylight savings option in your TV's settings. It will adjust the screen automatically according to the light changes in your home if it is enabled.

Hi there,

I agree with the above. You will need the main board. I have the boards for this tv if you're interested in purchasing them. My vizio took a remote to the screen. Let me know if i can help. Shoot me an email.

My Vizio has a shaded are on the left portion of the screen that flickers on and off and sometimes on the whole panel. It has a brownish tint to it. What is causing this? I have had it a year and a half.


It's lasted that long! Could the brownish tint be mistaken for pink? Sounds like the lamp(s) in the backlight panel are starting to go. Usually an expensive repair. Get an estimate but may be better to use the repair money on a better brand set. Vizio's have a very high failure rate.

"Finger Print" sized shaded area on screen


A shaded or dark spot on the screen is usually a bad pixel area and is caused by being hit or pressed to hard in that area. It could also be that the liquid crystal (LC in the LCD) in that area has become stagnant, try rubbing the area and around the area pressing firmly, just enough to see a color change in the screen area, but not too hard that the area turns black. Rubbing the area will move the liquid crystal around and sometimes refreshes a darkened area. If rubbing doesn't work, then it's a bad pixel area, and will eventually become a dead pixel area with time.
