Do a hard reset to this set and try. If it can't help you, visit the site referred here, and see whether it illustrates the fault to your TV. To make a hard reset to the set, unplug it from AC mains wall socket and re-plug it back after 3 minutes or so. Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" or "Flipcard" option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. You can also click the [Home] tab to the latest updates. It will make search easy. There are more than 1300 posts to different brand TVs now. Pull up older posts there.

SOURCE: LCD TV SCREEN PROBLEM RED HORIZONTAL LINES OF DOTS ALL OVER SCREEN PLEASE HELP

I unplugged the TV and now the picture is back.I read that the LCD's are vunerable to static build up so unless my daughter is using her TV I unplug it.

I was thinking about getting a large LCD for the family room but I'm not going to until they improve on this technology.

Good luck to everyone!.

Cheers.

SOURCE: LCD TV with horizontal lines rolling up screen

Find someone in an area that the Company will ship to and send them the money to get the replacement board. then give them the shipping address and have them send it to you . I would be willing to help if all it will cost me is the time. You would have to take care of the E-Bay Bill and The shipping costs from my location to yours.

This should be repairable. It may be the LVDS Cable or the Main board problem. The only other problem is the T-Con Board.

SOURCE: We also have a Vizio with red horizontal lines and our TV is new

It's possible that the motherboard or the controller board for the screen is defective. At this point, I would use the warranty from Vizio. It should be no doubt that it covered. Here's the info you will need from the Vizio web site.

Vertical lines showing up after being on for awhile


Eh, I can't be too sure, but it sounds like it's either a heat issue, a signal issue, or a backlight issue. Either way, if it's still under warranty I'd send it in.

Model# kdl-40w4100 Serial # 8051767 2 years old Horizontal lines in 4.5 inch blocks at the top of the screen


I have the same tv model KDL-40W4100 and around the same age. At the moment I have 16 of
these horizontal lines over the entire screen and they seem to be grouped into 2 lines per row. They are also around 4 inches and two pixel rows high. I have been looking over the Internet for months and found nothing to troubleshooting this issues. In the last few weeks more and more of these groups of lines have been showing up and now i am up to 16 of them and it is becoming unwatchable. Any help from anyone would be greatly appreciated. I also attached a picture to describe it better. Thanks!

The problem with Canon PowerSHot S60 Camera.


Your image sensor might be faulty. It is what connects your LCD and the picture in the issue of the horizontal lines. have it checked. Try checking your aperture too.

Distorted picture when looking through view finder or lcd screen


the video playback is sampled off the video out and independently processed sorta like a TV signal to project on the lcd screen.
horizontal lines means you lost sync circuit and needs troubleshooting. Hopefully maybe a bad connection with a ribbon cable for the ICs and components are hard to change and jammed tight. I would order a video board.
