Vizio LCD Green Pixels

Hello there...hopefully you can help. I have a 6 month old Vizio VW37L TV and recently the dark brown colors displayed on screen are outlined in bright green pixels. Very annoying. This seems to come and go and is mostly noticed when watching TV, not movies through the HDMI. Vizio customer support just suggested resetting the TV settings. Already did that. Any ideas?

    I have green and purple pixels which progressively gets worse as the tv warms up. It becomes unwatchable.

    I have the same issue with green pixels randomly appearing along the outlines of shapes and in the black border of the lcd screen. I am taking mine back to Costco (purchased it about 45 days ago). It has to be a defective display if you ask me. (Vizio model VO42L)

    I have the same problem. I called Vizio a couple months ago. They said it was a known power issue and to just unplug the t.v. and then plug it in again. That worked for a while, but they're back, now in purple in green. The Vizio customer service person told me (after 30 minutes) to take a photo of the screen and email it to

    I have bright green pixels on all the dark colors, especially on black. I have a Vizio VX37L, a year old. I suspect a power problem, how to fix it???

    I have the same problem with the 40 inch. Green pixels in all black areas and it is progressively getting worse. Called Costco concierge service and the repair guy says a bad motherboard and video card that they will replace. Vizio is getting many of these calls.

    I have the exact same problem. I have a 47" SV470XVT1A. I'm not sure if anyone is familiar with adobe photoshop, but it reminds me of the mask feature which highlights a similar color in a photo so you can alter just that selection. In the case of the vizio, there is a green pixely mask that glows and crawls over the dark images on my screen. I have a repair guy coming on Tuesday. Vizio seems to be familiar with the problem.

    I have the same problem. I have a 47" Vizio SV470XVT1A. It reminds me of the mask feature of a photo editing program. Where you click on a spot in a photo and simiar areas/colors in the photo all start glowing in a pixely way. Same thing on the Vizio. It glows and crawls on the screen in a green mask on all of the dark colored images on the screen.

    Ours just started doing the same thing (47"HDTV) on the dark colors. Second TV, the first had 2 gray lines that rolled up the screen. When this one goes back I will get another brand.

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.

I don't know if this will work for everyone with this issue, or even if it will work for me in the long run, but I seem to have resolved the issue (for now anyway) by taking the back off of mine and reseating all of the connections. Mind you, I don't have a warranty with mine as I bought it from a private party.

If you do this, do disconnect the power and A/V connections before you take the back off the set. Also, it's a good time to blow out any dust build up.

On another note, the pixeling effect is known as graphical artifacting, and can be caused by a faulty component or by heat. My set does get kinda warm, so I have moved it to a well ventilated location. So far so good!

I have a vizio model vw37l hdtv 10a, got a hit on front panel that made a small crack which messed up the picture in that area,what part needs replacing?

The set is finished- sets like this use a display panel- it is the entire front screen unit and a sealed unit at that.

Cost of the entire panel unit even if available will cost more than the set did when new ( not counting labor to remove and replace it).

Buy a new set and note all LCD and Plasma like sets have this issue as the display panel is very fragile.

Hey there, I have a 6 month old vizio 32" LCD 60hz

LCD inverter module may have encountered a failure. Most common is an electrolytic capacitor failing in the power supply. Examine the board to see if any of the caps have a bloated or raised top, they should not be swollen or leaky. If so find the replacement capacitor # on line and replace. You will require a modicum of soldering skills. You indicate the tv is 6 months old.
Return it for warranty service, do not open your tv or you will void your consumer warranty.

I have a vizio vw37L and after about a min or so the picture goes out but it still has sound

Does the screen go black or does the screen turn off? To determine this, cup your hands place them against the screen with your face in your hands. This effectively blocks all other light out, if the screen appears to be lit even though it is black, the screen is still on.
If the screen in on but black, 1. Check the cables that are attached. If there are separate cables for the video and audio, make sure the video is properly inserted. 2. There is an internal problem with wiring. Check your warranty and try and return it or get it repaired.
If the screen is off, 1. The lamp is burned out inside the tv. This is usually a free fix if the tv is under 2 years old. Contact the establishment where you purchased it or the manufacturer for details.

My Vizio LCD TV screen fades to dark. Sound stays on.

I w having this same issue when watching a Blu-Ray disc. I found it to be dependent upon what picture mode the TV was set to. By this I mean certain picture modes would cause the TV to dim during dark scenes of a movie. Changing the picture mode helped a lot.

Vizio screen went off but power light is still on

may be a mainboard problem. If you can see the orange light it usualy means that there is power running through the TV... usually inverter boards are a problem when you do not see any backlight at all.
