Vizio VO47L FHDTV10A black screen no light


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.

Change your aspect ratio to full. You are on just scan. When on Just scan mode this is normal. They have to have that to be THX compliant. Just change your aspect to full or 16:9 and you will be fine.

My vizio has to warm up before the screen turns to its regular blue no signal screen, and then when it does there are vertical lines all across the screen. Any solutions?


Hi:
This problem may be due to a faulty T-Con board, but first check the power supply for faulty Capacitors, there may be swollen of puffy tops on a couple of capacitors usually located near the connector plug going from the PS to the Main board. If all capacitors look fine then replace the T-Con board.

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.

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.

Vizio 42 in TV LCD HDTV white line across to of


That white line (usually jagged) is actuallly part of the transmitted picture. However, you are not intended to see it because it is located in what is known as the 5% overscan area. Your TVs today are more than just cable ready... they are a versital, technology filled multimedia display. You can see that line because the screen size or wide mode you are using is intended for 1080p/24 signals. You have 0% overscan with this screen size setting. This allows you to see ALL of the picture, including portions of the picture the broadcaster did not intend for you to see. You can change your screen size using the Wide feature in the Setup menu. See pg.62 of your user manual for details and descriptions of the various wide modes.
