  If your LG LED TV displays images but produces no sound, try pressing the VOL + or - button. Also, check if the sound is muted by pressing the MUTE button.

  If the image appears slowly when you turn on your LG LED TV, note that the image is muted during the product startup process which is normal. If the image doesn't appear after a few minutes, unplug the TV for 30 seconds and then try again. If the image still doesn't appear, no answer.

  If subtitles are not working on your LG LED TV, first, check if the file plays correctly on a PC to ensure it is not damaged. Then: * Make sure the video file and subtitle file have the same name. * Ensure both files are located in the same folder. * Verify that the subtitle file type is supported. * Check if the subtitle language is supported (you can check the language by opening the subtitle file in Memo Pad).

  If afterimages (ghosts) appear when your LG LED TV turns off, it could be due to pixels damaged from a fixed image displayed for a long time (image burn). To prevent this, use a screen saver.
