  There might be several reasons: * Ensure the power cord is properly connected to the outlet. * The signal cable between your PC and the device might be loose; double-check the connection. * The input signal might not be selected; use the INPUT menu on the remote to check. * The frequency range from the PC (video card) might be incompatible. Consult the manual's specifications to adjust the frequency range.

Why does after-image appear on my LG 49SE3B?
- B
  Bryan WrightAug 27, 2025
  An after-image may appear because: * The pixels may be damaged if a fixed image is displayed for an extended period. To prevent this, use the screen-saver function. * Image sticking can occur when a dark image is displayed after a high contrast image (black and white or gray). This is normal for LCD screens.

  If the screen color on your LG Media Player is abnormal, try setting the number of colors to more than 24 bits (true color) via Control Panel - Display - Settings - Color Table menu in Windows. Check the connection status of the signal cable and re-insert the PC video card. Note that several pixels (red, green, white, or black color) may appear on the screen, which is not a malfunction of the LCD, but attributable to its unique characteristics.
