  1. 1

    Turn off the Sony WEGA television. Leave the set off for a few minutes, then turn it back on. Occasionally the TV may run into playback issues causing the white line. Leaving the TV off for a few minutes can correct this.

  2. 2

    Check the cable connections running into the Sony WEGA Plasma TV. Make sure the cables are firmly seated. If the cables are not inserted correctly, it can cause video issues, including white lines.

  3. 3

    Disconnect input devices from the Sony TV. If the line disappears when you change the input, you know the issue is either with the connected device or with the cables, not the TV. However, if the white line is still present, the problem is with the TV.

  4. 4

    Launch your computer's Internet browser and make your way to the Sony Style website. Select the "Support" option, then choose your Sony WEGA plasma TV model. Download the updated firmware.

  5. 5

    Open the downloaded file to launch the computer's Zip software. If you do not have Zip software installed, you can obtain a free trial version at Select an extraction location and click "Unzip."

  6. 6

    Connect your USB flash drive to your computer, open "My Computer" or "Computer" and double-click the removable device icon. Click-and-drag the extracted files onto the USB flash drive. Once the file transfer has finished, disconnect the flash drive from the computer.

  7. 7

    Insert the flash drive into the USB port on the back of the Sony WEGA plasma TV. Power the TV on and it automatically detects the memory device. Wait for the system to upgrade itself from the flash drive. Once complete, remove the flash drive from the TV. Updating the firmware in this manner takes care of many problems with white lines.
