SOURCE: white flickering line across top of screen

Set the screen format using your TV's menu. Do not set the format of the screen using your provider's receiver. I had this prob with a few channels with a dish provider when I set the format with the remote from the dish provider. I picked up the TV's remote, went into the menu, set the format, problem fixed.

Hello
To replace the CCFL lamps, you have to disassemble the LCD module. It is a very skilled work, as CCFL lamms are very brittle. and should be handled carefully. It will be best to get this set repaired by any expereinced service technician.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Why do I have a green line on the edge of my screen? If you have a thin green line on the edge of the screen when using an HDMI cable to connect to a cable or satellite box this is usually caused by the box.
To test to see if this is a box issue you will want to take the following steps:
If the TV has a Horizontal position setting in the menu you can adjust the position to see if the line disappears.
You can also change the Wide setting to the Zoom or Panoramic option to see if the line disappears.
If the line disappears you will want to look into getting a different source box.

Your display may be flickering for several reasons. You will want to take the following steps to rule out the most common reasons for the display to flicker:

1. Reseat all cable and connections to the television from your devices. Physically remove the cables from both the television and the device and reconnect them.

2. Check your Advanced Video settings in the Vizio TV menu some of our Vizio televisions will allow you to adjust the following settings under the Advanced Video settings:

Ambient Lighting

Backlight Control

Advanced Adaptive Luma

If you have any of these options available please turn all of them off to see if this resolves the display flickering.

If the above steps have not resolved the issue please take the following steps in the order presented:

1- Power off TV

2- Unplug TV from outlet

3- Press and hold in the power button on the TV for 30 seconds (while it is unplugged from the wall)

4- Release the power button

5- Plug in the TV into a different outlet

6- Power the TV back on

There is also a factory reset option in your menu under the SETUP section. It will say either "reset all settings" or "system reset". We recommend that you reset all settings as well to see if this resolves the issue. If this does not resolve your problem please contact our technical for further assistance.
If the line stays in the same spot when changing the above settings please contact our technical support.

Monitor flickers with lines across screen


screen is going bad which is why its flickering and has the lines across the screen. Theres a board behind the lcd and when that doesn't process the voltage properly it can cause the screen to flicker. White lines across the screen means the screen is going bad. At this point unless your monitor is under warranty, go ahead and replace it.

White flickering line across top of tv with non HD channels


It appears that when you go back to normal tv from hdtv you are able to see the overscan area. Change the aspect of your image with the appropriate button on your Vizio remote and or cable remote. Apparently the button that changes the aspect on the Vizio remote is the wide button. The cable remotes will usually have hd zoom (#), aspect or format.
