SOURCE: yellow line on left side of screen-

If this is only happening on one input like your cable input and the dvd player is working great on a different input, then the issue can possibly be signal related and not a problem with the tv, if this haapens on any input you are watching, check to see if it affects the menu if it does then your looking at a Logic board issue, if it doesn't affect the menu but happens on multiple inputs then you have to replace the signal board

SOURCE: The screen is dark on the left side and Colored vertical lines

If you have tried using different input devices, looked for loose contacts
in power outlet, RC Jack, cable and connectors, the TV might need service.

My Vizio TV has a bar of colored lines running veritcally over the picture. Should I replace the T-Con board?

What causes vertical colored lines on a TV screen? When a TV is showing vertical colored lines, a loose wire cable in the TV might be the cause. If you knock on the back of the TV, the vertical colored lines MAY disappear temporarily. This is a sign that a cable is loose or the T-Con board is faulty.

My LCD TV has a vertical line on the right side of the screen. What causes that?

I hate to give you bad news but I believe this will be a panel issue and it's not going to be fixable. You can try a different tcon board but I don't think it will help

I have multi colored vertical lines across the entire screen. The menu screen is perfectly legible when selected on the remote and will go on and off like it is suppose to.

If this tv vertical colors lines problems happen by itself,tv problems not causes by u or an object by hitting forces to the tv LCD screen panel itself.The tv board that call the T-CON board it is dead,this board sit in the bottom in the middle of the LCD screen panel.Must be replaced the T-CON board to solve tv vertical colored vertical lines.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish T-CON board for the replacement.If causing by u or an object by hitting forces it to the LCD screen panel itself.The tv not worth a whole tv anymore,because by replacing the tv LCD screen panel will cost the same as a new tv.
