From the Vizio FAQ:http://vizio.custhelp.com/app/answers/detail/a_id/29What is the flashing white line on the top of my screen?Published 09/01/2010 12:03 PM | Updated 10/08/2010 09:51 AMThe line that you see is part of the broadcast signal that is being transmitted to your TV.To hide the line you will want to increase the the V-position on your TV.This option on most TV's is located under the H/V Position option in the Setup Menu on your TV.---HTH!

You need to set-up your inputs to match the desired output of the television. If you have a cable box, checkthe settings off on all resolutions to be supported. If a PS3, do the same. ETC.

I had same problem 3 times during first year with vertical lines and tv constantly reboot. If you have same issues this means your tv broke and need to be fixed. Register tv with samsung and schedule the technicians for repair. If it was sold by amazon you have warranty if not you may not have it. If you tv more than 50 inches tech will fix it at your home. Good luck

I have the same problem, same tv, same dvi to hdmi adapter, etc...Except I've got an ATI Radeon 8500. I wonder if it's an issue with the tv input and not the video card? Did you ever find a resolution?

After replacing the screen, i got white lines down the middle. I dont know if its a general problem or just the screen i got.

Amazon will take this TV back within 30 days of purchase and refund your money. They will even give you a pre paid shipping label as far as I know. Vizio's warranty is 1 year parts and labor. I would suggest an extended warranty for any new TV. Square Trade is reputable. In the end if they can't fix it, you could end up with a newer model if this TV is no longer in production. I don't know how Vizio handles warranty claims, I have never had to use them yet. I have read good things about them online and also bad things. Same with every brand really. Good luck!

I went into menu/source" and changed the input to "HDMI". The line went away!!If you dont have HDMI, change the input source to whatever you are using. This should get rid of the line.You should not see the line in any setting e.g. 16:9, 4:3, just scan etc.

Mine just went out today. I purchased it in the beginning of November. Trying to decide if I should see if Amazon will refund me and buy a different TV or just get it replaced by Vizio. I'm a little worried about the longevity, since it went out so quickly and others are experiencing the same problem.Loved the TV until it picture went out on me. I still have a 32" Vizio that's about 6 years old running strong.

I've had this TV for ~9 months and have not noticed this ... There is a light sensor in the TV; perhaps sunshine or ambient light is causing this?

I haven't had any problems with mine, but I did have a similar problem with another model and this is how it started before the whole screen went dark. I had a technician come by. He said it was the mother board and that he would fix it but he couldn't guarantee it wouldn't happen again. He said that it's best to replace the mother board, and if you have to do that you might as well buy another tv. I took a chance and he fixed the problem temporarily, then it died, so I threw it away and bought this LG. I've had it since July 2013 and it's worked fine. Mine is the same model in a 50-inch. I did buy the 5 year warranty just in case since it's new technology. With these smart tvs it's best to get the warranty because you never know. If it's still under warranty, you should return it and have them replace it before your warranty expires because once the mother board gives out it's too expensive to fix and you're better off buying another tv.

It's the bulb warming up 99% of the time. If it never goes away then check your HDMI cables by taking them out and reinserting them. Do this for all your electronic equipment because you never know which one it could be.If the blue/green tint never goes away after the above it's time to call mits.

I am also experiencing the "green lines" in 1080p. It looks good in 1080i. I called Philips support and the rep was trying to convince me that my Samsung LN40A550 LCD was not 1080p and I should call Samsung to see why I am seeing green lines. I was also very surprised when they said nobody has ever reported this issue. He had me upload the latest firmware but my unit already had the latest. I tried anyways and it didn't do anything.Anybody solved this problem yet?

You have a part going out on it, I had the exact same problem and it was more to get it fixed than it was to buy a new tv. I don't remember what the part was but it was expensive. Mine started doing that right after the warranty ended, and they won't fix it for free. Good luck with it. And I would stay away from their products in the future

This happens on my Panasonic Plasma on rare occasion (3 or 4 times a year.) It also happens with my Vizio LED. I believe its not a TV problem but a cable problem. I have Comcast and sometimes I need to unplug my cable box for a few minutes to re-boot it. Sometimes that works, but more often I'm just getting a bad signal from some unknown link in the chain from a live feed. It annoying but has never lasted. The other 99.9% of the time both TV work great.

I think we're experiencing image burn-in on our 2 1/2-year-old 1080p LCD TV. When an HD show is on, there are now visible vertical lines marking where the sidebars of standard definition programs would be, almost as if a standard size screen were placed over the widescreen. There's also some shadowing in the top half of the standard screen area. This is most noticeable when the picture background is light colored. We had no idea this would happen. We were considering buying the Samsung model you've got, but we spend more than 5% of our TV time watching standard definition programs, and many of our DVD/Bluray movies have black bars on top and bottom. Maybe we'll just get by with our current set until the image burn-in problem is eliminated.

I have not seen that happening on my tv, does it happens while watching different video sources, (BD, Video Games, regular t.v cable or satellite) or only in one of these? if it happens no matter the video source it may be the t.v. if its only on specific ones you could try to change cable connections or the problem could be on the video source.

White spots? Are they small? These could be bad mirrors in your processing board. My TV has 2 white and several black ones. Replacing the processing board with the mirrors is about 250... This is not related to the bulb it is a separate issue.

We used it with a cable box. We also needed to send it back to the manufacturer only after a couple months, because the screen had a big white line show up on it. Wish we never purchased it. I guess you get what you pay for!
