From the Vizio FAQ: http://vizio.custhelp.com/app/answers/detail/a_id/29 What is the flashing white line on the top of my screen? Published 09/01/2010 12:03 PM | Updated 10/08/2010 09:51 AM The 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!

Shortly after setting up a new DV-980H I experienced similar flash "bands" of white noise. The first DVD I played appeared fine (it may have been played at 480p). The second DVD had the issue being played at 1080p. At first I thought it was a scratch on the DVD but the problem has occurred with other DVDs, including new DVDs. The white bands flash predominately on the bottom third of the screen and occasionally on the entire screen. The Oppo DV-980H is set to upconvert to 1080i for display on a Samsung LNT4665FX connected through HDMI with the Oppo supplied cable. The only other problem I have had so far is some jerking of the video while playing some portions of one DVD. This appears more attributable to the DVD but I expected the Oppo to do a better job of buffering and oversampling to prevent this from being seen. ** I raised the issue of the flashes of white in an e-mail to Oppo over the President's Day weekend. Their Support group contacted me later that day! They belive the issue is due to a marginal HDMI cable. Rerouting the cable appears to have helped.

Great Granny,I would try to exchange or return the tv while you still can. Only a minority of Vizio's have picture problems and you are certain your tv has a sound issue. If you were to use external speakers you might still have a sound problem anyway. Good luck.

Very similar issue: flickering problem on this 55 inch. This all began about 24 months after purchase. Does anyone have a solution other than calling a service technician and paying for the repair yourself?

Check for loose wiring/loose fittings first. Second would be to try changing the resolution on screen. Last would be your monitor is going out. Let's hope that's not it.

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.

Yes I had that problem with my Samsung TV. I now have a brighter cleaner picture without the white spots.

There is no way that I know. When I installed mine, my cables were not fully seated and I saw a similar color issue. It is possible that one of your component or HDMI cables is not completely connected to the box or the TV/Devices. Check that your cables are firm and in the correct ports. If they are, you may try testing with another cable. Once my cables were set, my picture was perfect and I have had no problems with the box.

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?

I just got off the phone with Vizio's customer service. According to the person I spoke to the screen is matte. Who's correct, Vizio's customer service rep or the postings? I'll wait until I physically see the TV for myself.I appreciate your help.

There is a service bulletin out for this tv. I just had mine fixed by best buy under warrantee. The motherboard and the cable going to it short out and cause this issue. It will slowly get worse. Service bulletin ASC20130429001

Hi Kevin, I have experienced this noise. I bought it brand new and returned and exchanged it and the second television did this as well. You can read my comment on the comments page. Did you resolve this problem? CJ

I'm having this exact same issue with my TCL 40". If anyone has any ideas on how to to fix this besides buying speakers, it would be appreciated.

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.

I didn't have that particular problem. However, I did return the TV because when the TV was on there appeared to be a tear (the way a torn piece of paper looks) across the top of it. I bought a 60 inch Samsung plasma and I Love It!
