4. There Is A Thin Line Across The Screen (Verified)(367196) 1.bmp

A thin red, green, blue, or other colored line running through your LCD TV screen is, most likely, a line of dead pixels. It is also possible the line is coming from the device you have connected to the TV.

To determine where the line is originating, follow these steps:

  1. Turn the TV on.
  2. Press the SOURCE button to switch inputs.
    • If the line has disappeared, there is no problem with the TV. The line is coming from the device. You must contact the manufacturer of that device for further support.
    • If the line has not disappeared, then the problem is caused by the TV and it must be repaired. Click the Create online service request button below to have the TV repaired.

Terms:

Dead pixels: Pixels on the TV's display that cease to function properly, causing lines or areas of color distortion.

Inputs/SOURCE: Refers to the various devices (e.g., cable box, gaming console) that can be connected to the TV and selected using the SOURCE button.
